distinct in its large leathery grey stipules, but scarcely a separate species. 
The calyx-lobes are somewhat more rigid, broader, and shorter than in the 
type.

Calycis tubus obconicus, bractearum vel stipularum connatoram 4 vel plurium 
dissimilium involucro cinctus a quo internodio brevissimo separatus ; limbi 
lobi 4, lanceolati, ampli, subrigidi, vena media forti, eum dentibus subfili- 
formibus alternantes. Corolla campanulata, tubo gracili longiuseulo fauce 
glabrescente ; limbi lobi 4, intus dense villosi, valvati. Stamina 4 fauci 
corolle inserta, filamentis pro rata longis ; anther dorso affixee, exserte. 
Discus parvus, Ovarium 2-loculare ; stylus gracilis, stigmate lobis 2 parvis 
rotundatis latis obtusis; ovala in loculis numerosa, placentis septo medio 
affixis inserta. Capsula parva, venosa, turbinata, a vertice loculicide 
dehiscens, calyeis segmentis erectis subfoliaceis persistentibus coronata 
bractearumque involucro cincta. Semina angulata, foveolata.—Herb:e vel

The habit, æstivation of the corolla, and character of the ovary and fruit, 
leave no doubt that this genus should be classed with the Hedyotideæ. Itis 
distinct as a genus in virtue of the relatively large size of the solitary axillary 
flowers, and of the very definite involucre of bract-like organs associated with 
the calyx and fruit. The habit is much like that of one of the coarser 
Ffedyotes ; but the conspicuous scales alternating with the calyx-lobes 
distinguish this plant readily from that genus,
