[edit] Description
Herbaceous and perennial plants, from tunicate, ovoid bulbs with brown, dry, brittle and papery tunics. The stems are simple or branched. The leaves are few, with the basal ones larger than the others; the blade is pleated, linear-lanceolate.
The inflorescences are rhipidia, few-flowered; the spathes are green, unequal, with the inner spathe exceeding the outer, apex brown, acute, usually dry. The flowers are short-lived, erect, unscented, actinomorphic; tepals spreading, distinct, blue to mauve with white markings, unequal, with the outer whorl more than 2 times than the inner; the anthers are diverging, appressed to the style branches; style slender, branching at apex of filament column and the branches diverging from the base, flattened, divided apically into two slender lobes, apically stigmatic. The fruit is an ovoid capsule with the apex truncate. Seeds many, prismatic, with a brown seed coat. The basic chromosome number is x = 7.
[edit] Taxonomy
Herbertia consists of 8 species, one of them is endemic to Texas in U.S.A, and the others are distributed in template regions of South America (Chile, Argentina, Paraguay, Uruguay Y Brasil). The genus is closely related to Alophia, Cypella, and Tigridia.
The name of the genus is dedicated to William Herbert (1778–1847), a prominent British botanist and specialist in bulbous plants.[1]
