3. GYMNOSTERIS Greene, Pittonia 3: 303. 1898. 



Diminutive leafless annuals with simple stems, bearing at the base a turbinate or 

 campanulate sheath composed of the united persistent cotyledons. Flowers few in 

 terminal bracteate heads. Bracts 4 or 5, herbaceous and free above, scarious and united 

 at base forming an involucre. Calyx vesicular and urceolate, scarious below, only the 

 tips herbaceous. Corolla salverform or slender-funnelform, white or yellow, marcescent- 

 persistent. Stamens sessile, borne in the corolla-throat. Capsule dehiscent, many-seeded. 

 Seeds obliquely cubical, the angles membranously margined or winged ; testa mucilaginous 

 when wet. [Name Greek, meaning naked and foundation in reference to the leafless stem.]
