floribus albescentibus vel purpurascentibus cleistogamis. 1-4, 

 pedicellatis, inconspicuis et perparvis; calice 2-partito ejus labio 

 inferiore minute 3-lobato et 5-nervato, superiore quidem 7-nervato: 

 corolla breviter et obtuse saccata et bilobata: capsula globosa, 

 multa perparva semina continente. 



Plant small, scapose, erect, simple, leafless or with a few 

 scales, with 1-4 pedicelled inconspicuous small flowers. Calyx 

 two parted the lower lobe minutely 3-lobed and five nerved, 

 the upper 7-nerved. Corolla two-lipped, bluntly saccate: capsule 

 globose with many minute seeds. 



This plant probably monotypic is distinct from l.Hricularia 

 Linn, and the other genera recently segregated from this by its 

 cleistogamous flowers. There seems some doubt that these minute 

 flowers are really cleistogamous, but even then the character- 

 istically peculiar shape of the flowers especially the corolla is suffi- 

 ciently distinctive. If these flowers are then really chasmogamous 

 and not cleistogamous they do not in any way resemble any of 

 the flowers of the other Utriculariaceae. 



The corolla is a subglobose sac-like structure with a slit 

 at one end and a blunt continuation of the sac at the insertion 

 below. The lobes are neither recurved or even reflexed or spread- 

 ing. The flowers are subcorymbose. The peculiar color of the 

 flowers too seems to bespeak no close resemblance to Setiscapella 

 suhulata (Linn.) Barnhart' {Utrictdaria subulata Linn.) of which 

 it was first made a mere variety resembling it in habit.

The name Aphyllon Mitchell, (1769)' antedated Rafinesque's
