Gentianella
Belongs within: Gentianeae.
Gentianella is a cosmopolitan genus of herbs bearing nectariferous flowers. Circumscription of the genus has been contentious; Australasian species were placed by Adams (1995) in a proposed segregate genus Chionogentias but this genus has not been recognsed by some other authors.
Characters (from Struwe et al. 2009): Annual, biennial, or perennial herbs; decumbent or erect. Stems usually sparsely branched above, rarely many stems from base. Stems terete or quadrangular. Flowers 4- or 5-merous, forming terminal or axillary umbelliform cymes, or borne singly. Calyx with a very short to well-developed tube, sometimes split to base on one side. Intracalycine membrane absent. Corolla infundibuliform, cylindrical, hypocrateriform, rotate, or campanulate. Aestivation convolute. Corolla shallowly divided or divided almost to base. Corolla tube may have vascularized fimbriae, non-vascularized fimbriae, or none at all. Fimbriae, when present, scattered, united in a ring, or arranged in a row at base of each corolla lobe. Plicae absent. Stamens inserted at or below middle of corolla tube. Filaments filiform and occasionally barbate below. One or two naked nectaries per corolla lobe present at base of corolla tube. Ovary sessile or with short gynophore. Style indistinct or absent. Seeds usually unwinged or rarely winged.
