Proxim. T. asiatice, a quo distincta mollit. filamentisque 
omnibus simplicibus huic charactere a genere toto recedit. 
In his omnibus testa foveolis exsculpta est, foveolis paucis- 
simis in novo meo genere, plurimis in Bonnaya bracteata, 
Testa (tegument) quam maxime coriaceum, albuminum firme

Super ; ex hoc oritur aspectus papillosus seminum humefac-

Pellicula testa est, testa Vandellia scabra Bonnaya bra- 
chiata in quibus et presertim priore reticulata est cellulosa et 
laxa, in utrisque. 
Raphe e cellulis elongatiusculis formata precursa est. In 
Bonnaya brachiata membranacea est, et hispidula pilis 
apice cruciatim fissis. 
r. Benthan says, while refering to the distinctive marks 
between Scrophularinee and Primulacee, in allusion to the 
Stamina of these two orders belonging to different series, 
t no trace of the inner series has as yet been ob- 
Served in Scrophularinee, except perhaps in Bamia, Without 
having any knowledge of Bamia, there can be no doubt that 
its dis is analogous to that of Scrophularinez ; and this again, 
although often incom plete, obviously represents either the whole 
oF portion of the inner series of stamens.
