For the 835,580 species in the Class Magnoliopsida (Dicotyledons), we average 4.30 observations each in our database; for the H Hawaii Desert-Thorn, we have 141 observations. Compared to other species in this Class, this species is moderately common.
A two-sample t-test can be used to determine whether the trend in observations of the H Hawaii Desert-Thorn is the same as the trend in observations of Magnoliopsida. Is this species just as common, as a proportion of all observations, as it once was? The answer is yes, changes in observation rate of this species do not significantly differ from changes in observation rate of its Class.
Herbs, shrubs, small trees, or climbers. Stems sometimes prickly, rarely thorny; hairssimple, branched,
or stellate, sometimes glandular. Leaves alternate, solitary or paired, simple or pinnately compound, without stipules; leafbladeentire, dentate, lobed, or divided.Inflorescencesterminal, overtopped by continuing axes, appearing axillary, extra-axillary, or leaf opposed, often apparently umbellate, racemose, paniculate, clustered, or solitary flowers, rarely true cymes, sometimes bracteate. Flowers mostly bisexual, usually regular, 5-merous, rarely 4- or 6-9-merous. Calyx mostly lobed.Petalsunited.Stamens as many as corollalobes and alternate with them, inserted within corolla, all alike or 1 or more reduced; anthers dehiscing longitudinally or by apical pores. Ovary 2-5-locular; placentation mostly axile; ovules usually numerous.Style 1. Fruiting calyx often becoming
enlarged, mostly persistent.Fruit a berry or capsule.Seeds with copiousendosperm; embryo mostly curved.
About 95 genera with 2300 species: best represented in western tropical America, widespread in temperate and tropical regions; 20 genera (ten introduced) and 101 species in China.
Some species of Solanaceae are known in China only by plants cultivated in ornamental or specialty gardens: Atropa belladonna Linnaeus, Cyphomandra betacea (Cavanilles) Sendtner, Brugmansia suaveolens (Willdenow) Berchtold & Presl, Nicotiana alata Link & Otto, and Solanum jasminoides Paxton.[1]
Genus Lycium:
Shrubs, often armed with thorns, pubescent with simplehairs. Leaves usually fasciculate on short shoots, petiolate or subsessile; leafblade small, plane or linear-cylindric, entire.Inflorescences solitary or fasciculate axillaryflowers; peduncle absent. Flowers pedicellate.Calyxcampanulate, 2- or 5-dentate or -lobed. Corollafunnelform or campanulate; tube short, limb usually (4- or) 5-lobed, enlarged at throat.Stamensinserted high in corolla tube, included or exserted; anthers oblong-elliptic, dehiscing longitudinally. Ovary 2-locular; ovules 1 to many. Style slender. Berry red, orange, yellow, or black, globose, ovoid, or oblong, fleshy or juicy; fruiting calyx slightly enlarged. Seedsnumerous or few, compressed, pitted.
About 80 species: South America, S Africa, a few in temperateEurope and Asia; seven species in China.[2]
