• Species: ZipcodeZoo has pages for 42 species, subspecies, varieties, forms, and cultivars in the Tribe Arundinarieae.

Genera

Arundinaria

Small to arborescent bamboos, spreading or loosely clumped. Rhizomes leptomorph. Culms diffuse to pluricaespitose, suberect to drooping, 1-7(-13) m tall, 0.5-4(-6) cm thick; internodes terete to flattened on one side above branches. Branch buds tall, with or without promontory, within 2-keeled prophyll, always open at front. Branches (1 or) 2-5(-7), subequal. Lateral branch axes always subtended by sheaths, without replication of lateral branches. Culm sheaths deciduous to persistent, blade usually recurved or reflexed, lanceolate, articulate. Leaf sheaths persistent; blade oblong-lanceolate or narrowly lanceolate, small to medium-sized, without marginal necrosis in winter, arrangement random, transverse veins distinct. Inflorescence an open panicle or raceme, flowering branches usually subtended by tiny bracts. Spikelets several to many flowered, slender; rachilla internodes extended, disarticulating. Glumes 1 or 2, mucronate; lemma similar to glumes; palea 2-keeled, apex obtuse; lodicules 3. Stamens 3; filaments free, slender; anthers yellow. Style usually very short; stigmas 2 or 3, plumose. Caryopsis dry, oblong. New shoots May-Jun.^[1] [more]

Atropa

Atropa () is a genus of plants in the nightshade family. Its best-known member is the deadly nightshade, Atropa belladonna. Its pharmacologically active ingredient is atropine. The genus is named after Atropos of the Three Fates, the one which cut the life thread. [more]

Daphne

Shrubs or subshrubs, evergreen or deciduous. Branches glabrous or pubescent. Leaves mostly alternate, sometimes opposite; petiole short. Inflorescence usually terminal, sometimes axillary, capitate or shortly racemose, sometimes paniculate, racemose, or spicate, with or without involucre; peduncle short or absent. Flowers bisexual or unisexual (plants sometimes dioecious), 4- or 5-merous. Calyx tube white, pink, or yellow, rarely mauve, campanulate, cylindric, or slightly funnel-shaped, exterior glabrous or pubescent; lobes 4 or 5, erect or spreading, alternately longer and shorter. Petaloid appendages absent. Stamens twice as many as calyx lobes, in two series; filaments short or absent; anthers oblong, included; connectives indistinct. Disk absent or annular, cup-shaped, sometimes elongated on one side. Ovary usually sessile or slightly stipitate, ovoid, 1-loculed; style terminal, short; stigma capitate. Fruit a succulent berry or dry and leathery, sometimes enclosed by persistent calyx, sometimes naked, usually red or yellow. Seed testa crustaceous, endosperm scanty or absent; cotyledons fleshy.^[2] [more]

Hypolepis

Plants terrestrial, often forming colonies. Stems subterranean, long-creeping; hairs reddish. Leaves scattered, arching, deltate, 45--160 cm [to 7 m]. Petiole glabrescent or pubescent, often with prickles, sometimes with stem buds near base; vascular bundles more than 3, forming O-shaped pattern in cross section. Blade 1--4-pinnate; rachises with prickles; nectaries absent. Segments pinnatifid, ultimate segments oblong, margins lobed. Veins free, simple or pinnately branched. Sori ± marginal at vein tips, discrete, mostly round, protected by revolute blade tooth, rarely inframarginal and unprotected. Spores ellipsoid, monolete, tuberculate or papillate. x = 26, 29.^[3] [more]

Trichocereus

Echinopsis is a large of cacti native to South America, sometimes known as hedgehog cacti, sea-urchin cactus or Easter lily cactus. One small species, E. chamaecereus, is known as the peanut cactus. The 128 species range from large and treelike types to small globose cacti. The name derives from echinos hedgehog or sea urchin, and opsis appearance, a reference to these plants' dense coverings of spines. [more]

At least 127 species and subspecies belong to the Genus Trichocereus.
