New combinations include: Greeneocharis circumscissa var. INFLORESCENCE: The inflorescence is a helicoid or scorpioid cyme (which is. Genera resurrected include: Eremocarya, Greeneocharis, Johnstonella, and Oreocarya. Recently the old Hydrophyllaceae (Waterleaf Family) was added to the. Although sampling is incomplete, this study generally supports the hypothesis of repeated, unidirectional dispersal events, from North to South America. Flowers often ebracteolate regular usually 5 merous cyclic tetracyclic. Character trait analyses support the multiple, derived evolution of perenniality, reduction in nutlet number, nutlet heteromorphism, smooth nutlet sculpturing, heterostyly, and cleistogamy. The Cryptanthinae is supported as monophyletic. Plagiobothrys was resolved as polyphyletic in three clades, these clades corresponding to previously named sections or groups of sections. The related genera Amsinckia and Pectocarya were resolved as monophyletic and most closely related to various clades within Cryptantha s. Boraginaceae (Synonym: Lennoaceae, Hydrophyllaceae) family comprises about 135 genera. Based on these analyses, we propose resurrection of the genera Eremocarya, Greeneocharis, Johnstonella, and Oreocarya, and recognition of a newly delimited Cryptantha s. Boraginaceae have erroneously been associated with helicoid cymes. was found to be polyphyletic, with its members placed among several well-supported clades. These data were used to assess phylogenetic relationships using parsimony, maximum likelihood, and Bayesian inference methods. l., exemplars of the related genera Amsinckia, Pectocarya, and Plagiobothrys, and four outgroup taxa were sequenced for two gene regions, the nuclear ribosomal gene, ITS, and the trnLUAA intron region of the chloroplast genome. Fifty samples of 45 species of Cryptantha s. The genus exhibits an amphitropic distribution, occurring in temperate and desert regions of western North and South America. 64(1): 160-161.Cryptantha (Boraginaceae) is a group of approximately 200 annual and perennial species, representing two-thirds of the diversity within subtribe Cryptanthinae. 300 species: mostly in North and South America, with a few in Africa, Asia, and Australia one genus with one species in China.ДЇang Rhui-cheng & Huang Shu-hua in Wu Cheng-yih, ed. Seeds usually with a sculptured or pitted coat endosperm enclosing a small embryo.Д®ighteen to 22 genera and ca. Fruit a loculicidal capsule, rarely also septicidal or opening irregularly. Styles 1 or 2, usually lobed or divided stigma capitate. Ovary superior, 1- or 2- (several) locular, with 2 parietal placentae ovules few or numerous. Stamens usually 5 filaments attached to corolla, often alternating with scalelike appendages anthers 2-locular, longitudinally dehiscent. Corolla gamopetalous, campanulate, tubular, or rotate lobes overlapping in bud. Calyx В± gamosepalous, sinuses sometimes appendaged.

Flowers bisexual, actinomorphic, usually 5-merous, often showy. Inflorescences solitary flowers, cymose, or paniculate. Leaves alternate or opposite, occasionally in a basal rosette, simple or variously lobed or divided, without stipules. Herbs or shrubs, glabrous or pubescent, occasionally glandular, bristly, or thorny. In a scorpioid cyme the branches are alternately on opposite sides of the developing. They are usually 4 to 6 inches (10 15 cm) long, deeply divided, resembling the leaves of ferns. The entire plant is coated with stiff hairs that are often glandular and sticky-tipped.

Authors: Ruizheng Fang & Constance Lincoln Heluciud cymes are frequent in Boraginaceae and Hydrophyllaceae. Common phacelia is an annual herb with sprawling to erect reddish stems 6 to 30 inches (15 75 cm) long. In a scorpioid cyme or in the species of Chenopodiaceae she investigated, to cincinnus, the branches develop from each other in an alter- consist of вЂone to numerous thyrses.
