even persistent on the capsule ; the second will comprise such as 
do not possess these characters, and is confined at present to a 
single species: thus—

8. Browallia speciosa, Hook. Bot. Mag. tab. 4339. The much 
larger flowers of this species, its more acutely-lobed and deeper- 
cleft border, and constantly smooth ovarium, are characters of 
hardly sufficient importance to constitute a generic difference ; 
but at all events, with such marked distinctions, Leogyne will 
form a good subgenus. 
From the above enumeration B. Jamesoni has been excluded, 
because it differs in its characters, in the number of divisions of 
its calyx, in the shape of its corolla, the form and position of its 
stamens, and the structure of its stigma.

STREPTOSOLEN., 
I have already alluded to the propriety of excluding from 
Browallia the species described under the name of B. Jamesoni, 
as it possesses many essential characters at variance with that 
genus. All the species of Browallia are herbaceous, while the 
plant above-mentioned is suffruticose, forming a branching shrub 
4. or 6 feet high, with very rugous, coriaceous and scabrid leaves ; 
the inflorescence is also more corymbose, and the structure of 
the flower differs from that of Browallia in the followmg parti- 
culars. The calycine tube is crowned with four, rarely with five 
teeth ; the corollais not hypocrateriform, and its tube, instead of 
being slender and cylindrical, swells into a funnel-shape, imme- 
diately as it emerges from the calyx, and the contracted basal 
portion soon twists half a revolution, so that the border becomes 
actually resupinate ; owing to the want of the contraction in the 
throat, the border does not assume the figure of a rotate 5-lobed
