Exochorda Exochorda is a small genus of flowering plants in the family Rosaceae, native to China and central Asia (Turkestan). They are used as ornamental plants with the common name pearl bush, or pearlbush. Numerous species have been described on the basis of differing appearance and geographical separation, but a systematic study revealed that the different types are closely related and probably all descended from a single species that formerly had a wide distribution that has been fragmented by habitat loss. As a single species the correct name is "E. racemosa".

Ixora Ixora is a genus of flowering plants in the Rubiaceae family. It is the only genus in the tribe Ixoreae. It consists of tropical evergreen trees and shrubs and holds around 545 species. Though native to the tropical and subtropical areas throughout the world, its centre of diversity is in Tropical Asia. "Ixora" also grows commonly in subtropical climates in the United States, such as Florida where it is commonly known as "West Indian Jasmine". Other common names include "viruchi", "rangan", "kheme", "ponna", "chann tanea", "techi", "pan", "siantan", "jarum-jarum/jejarum", "jungle flame", "jungle geranium" among others. The plants possess leathery leaves, ranging from 3 to 6 inches in length, and produce large clusters of tiny flowers in the summer. Members of Ixora prefer acidic soil, and are suitable choices for bonsai. It is also a popular choice for hedges in parts of South East Asia. In tropical climates they flower year round and are commonly used in Hindu worship, as well as in ayurveda and Indian folk medicine.

Isoetes occidentalis Isoetes occidentalis (western quillwort) is a species of quillwort in the Isoetaceae family. It can be found in aquatic habitats of coastal Alaska and British Columbia south to California and Colorado. It is frequently found on Vancouver Island and around the Fraser Valley region. It bears 10 to 30 or more rigid, dark green leaves, each 5 to 20 centimeters long. The velum covers one fourth to one third of the orbicular sporangium, which is 5 to 6 millimeters in diameter. The ligule is shaped like a shortened triangle. The white megaspores are 500 to 700 micrometers in diameter and bear sharp ridges and crests. The microspores are 36 to 43 micrometers long. Though the leaves seem to bear resemblance to those of "I. lacustris", especially the occasionally occurring reddish base, "I. occidentalis" is a hexaploid and "I. lacustris" is a decaploid.

Coryne eximia Coryne eximia is a species of athecate hydroid belonging to the family Corynidae. It seems to be an almost ubiquitous species, having been recorded in coastal locations worldwide. This is a red or pink hydroid growing to 15 cm tall but usually only half this size. It is rather similar to "Coryne muscoides" but differs in that all the branches usually come off one side of each stem and that most of the stems and branches are smooth with only small, irregular ringed sections. As with "C. muscoides", each branch ends with a cluster of knobbed tentacles. It can be found in a wide range of rocky shore habitats but is also abundant on kelp and can also often be found on the ropes and floats of lobster pots.

Fern A fern is a member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having certain tissue that conducts water and nutrients, and having branched stems. Like other vascular plants, ferns have leaves, and these are "megaphylls", which are more complex than the "microphylls" of clubmosses. Most ferns are leptosporangiate ferns, sometimes termed "true ferns"; they produce what are called "fiddleheads" that uncoil and expand into fronds. The group includes about 10,560 known extant species.

Phytomer Phytomers are functional units of a plant, continually produced by root and shoot meristems throughout a plant's vegetative life-cycle. The phytomer unit originates at the shoot (or root) apex, and a typical phytomer consists of a node to which a leaf is attached, a subtending internode, and an axillary bud at the base of the leaf. Each component of a phytomer can continue to differentiate and grow. Increases in a phytomer can be measured using the rate of phyllochron (rate of appearance of leaves on a shoot). Related to the phyllochron is the plastochron, which is the rate of leaf primordia initiation. Since many more leaf primordia are initiated than leaves develop, the plastochron develops at a much faster rate (sometimes as much as twice as quickly) as the phyllochron.

Heppia Heppia is a genus of olive, brownish, gray, or blackish squamulose, crustose, or peltate lichens. It is in the family Heppiaceae. It grows on rock or soil in arid sites around the world, in habitats similar to those favored by "Peltula", which is similar but has a different cyanobacterium as the photobiont. It lacks a medulla that is separate from the photobiont layer. It is a cyanolichen with the photobiont cyanobacterium being "Syctonema" (or "Syctonema"-like). The lower surface is paler than upper surface, and has numerous rhizoidal hyphae attaching it to the substrate. The fruiting structures (ascomata) are apothecias immersed in the thallus with red to red-brown urn shaped (urceolate) to flat or slightly convex discs. An exciple may or may not be present.

Commelina tuberosa Commelina tuberosa is an herbaceous plant in the dayflower family native to Mexico but grown worldwide as an ornamental plant. It is characterized by its purple-splotched spathes with free margins, its bright blue petals of equal size, its tuberous roots, and its four to ten flowered lower cymes. In the wild, it is encountered in moist fields, open forests, or pine-oak forests. The species is sometimes considered to include the species "Commelina coelestis", "Commelina dianthifolia", and "Commelina elliptica", such as in the Flora Mesoamericana. When these are treated as separate, they are often referred to as the ""Commelina tuberosa" complex". Horticulturally, the species are often treated as separate entities because of their differing habits and leaf shapes. In this sense, "Commelina tuberosa" is a low-growing plant with long narrow leaves.

Hawaiian lobelioids The Hawaiian lobelioids are a group of flowering plants in the bellflower family, Campanulaceae, all of which are endemic to the Hawaiian Islands. This is the largest plant radiation in the Hawaiian Islands, and indeed the largest on any island archipelago, with over 125 species. The six genera can be broadly separated based on growth habit: "Clermontia" are typically branched shrubs or small trees, up to 7 m tall, with fleshy fruits; "Cyanea" and "Delissea" are typically unbranched or branching only at the base, with a cluster of relatively broad leaves at the apex and fleshy fruits; "Lobelia" and "Trematolobelia" have long thin leaves down a single, non-woody stem and capsular fruits with wind-dispersed seeds; and the peculiar "Brighamia" have a short, thick stem with a dense cluster of broad leaves, elongate white flowers, and capsular fruits.

Cycad Cycads are seed plants with a long fossil history that were formerly more abundant and more diverse than they are today. They typically have a stout and woody (ligneous) trunk with a crown of large, hard and stiff, evergreen leaves. They usually have pinnate leaves. The individual plants are either all male or all female (dioecious). Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly and live very long, with some specimens known to be as much as 1,000 years old. Because of their superficial resemblance, they are sometimes mistaken for palms or ferns, but they are not closely related to either group.

Hemerocallis fulva Hemerocallis fulva, the orange day-lily, tawny daylily, tiger daylily, fulvous daylily or ditch lily (also railroad daylily, roadside daylily, outhouse lily, and wash-house lily) , is a species of daylily native to Asia. It is very widely grown as an ornamental plant in temperate climates for its showy flowers and ease of cultivation. It is not a true lily in the genus "Lilium", but gets its name from the similarity of the flowers and from the fact that each flower lasts only one day. It is occasionally mistaken for the unrelated true lily known as the "tiger lily", "Lilium lancifolium", which is different in growth habit, floral construction and coloration.

Echinocereus rigidissimus Echinocereus rigidissimus, commonly known as the Arizona Rainbow Cactus or Rainbow Hedgehog Cactus is a solitary, growing cactus, that rarely branches or offsets with age. "Echinocereus rigidissimus" grows to a height of up to 30 cm, and a width of 11 cm when mature, with pectinate radial spines curved slightly towards the stem, the new spines are initially reddish to magenta and fades to a yellow or light pink colour when they mature. "Echinocereus rigidissimus", flowers in flushes throughout the spring season, with multiple buds borne atop the plant from younger areoles, the flowers are bright pink in colour with a white coloured throat. If pollination is successful, "Echinocereus rigidissimus" forms circular shaped, greenish to dark purplish fruit, with white flesh and dark brown to black seeds approximately 3 months after flowering. Since it rarely offsets, "Echinocereus rigidissimus" is propagated by seed.

Leymus multicaulis Leymus multicaulis, also known as manystem wild rye or manystem lyme grass, is a species of the "Leymus" genus. The species name of manystem wild rye, "multicaulis", suggests the “many stems” of the species. "Leymus multicaulis" is considered a type of grass. Manystem wild rye has only one cotyledon in each of its seeds. The xylem and phloem within the roots are arranged in a ring pattern. The vascular bundles are scattered throughout the stem. These traits make "Leymus multicaulis" a monocot. "Leymus multicaulis" is a flowering plant, or angiosperm.

Emplectopteridaceae The Emplectopteridaceae were pteridosperms known mainly from Permian floras of the Cathaysian Realm. They were mostly shrubby plants with a scrambling or upright habit, and favoured a range of habitats from arid to moist or even aquatic. The foliage is the most abundant known remains of this family, having been reported from Artinskian to Wuchiapingian macrofloras of both north and south China. The venation is characteristically flexuous to loosely anastomosed, and rather different from the more regularly anastomosed venation of the true gigantopterids (with which the Emplctopteridaceae fronds used to be confused). The stratigraphically older leaves tended to be twice pinnate ("Emplectopteris"), the later leaves once pinnate or entire ("Gigantonoclea"). The ovules were bilateral and attached to the underside of the leaves / fronds that did not differ significantly from normal vegetative foliage Pollen organs were a complex of filiform microsporophylls each bearing 2-8 sporangia (assigned to the fossil-genus "Jiaochengia").
