SIPHONYCHIA, Torr. ^ Gr. 



Calyx fere ad medium 5-fidus ; tubo obovato, fructifero 

 utriculum membranaceum includente ; lobis petaloideis 

 planis, vel apice incurvis, muticis. Stamina 5 et petala 

 subulata (potius filamenta sterilia) fauci calycis inserta. 

 Stylus gracilis apice bilobus. Semen e funiculo basilari 

 introrsum resupinato-pendulum ; radicula supera ; cotyledoni- 

 bus funiculo aversis. — Herba longe humifusa ; foliis planis 

 bistipulatis, internodiis multo brevioribus.

Calyx five-cleft to near the middle ; the ovoid tube her- 

 baceous, somewhat indurated in fruit ; the lobes petaloid 

 (white), oblong, very obtuse, plane and entirely inappen- 

 diculate, imbricated in asstivation, the apex more or less 

 inflexed. Petals (or rather sterile stamens) inserted on the 

 throat of the calyx opposite the sinuses, subulate, exactly 

 resembling the filaments. Stamens inserted on the throat of 

 the calyx, as many as its lobes, and opposite them : fila- 

 ments subulate : anthers didymous, introrse, two-celled ; 

 the cells opening longitudinally. Ovary ovoid-oblong, one- 

 celled : style slender, exserted, two-lobed at the apex ; the 

 lobes introrsely stigmatose. Ovule solitary, campylotropous, 

 pendulous on the incurved apex of a long filiform funiculus 

 which rises from the base of the cell ; the micropyle supe- 

 rior. 



Fruit a hyaline utricle, inclosed in the calyx-tube. Seed 

 lenticular, smooth, resupinate on the incurved apex of the 

 funiculus. Embryo coiled into a nearly complete ring, sur-
