208 Mr. J. Miers on the genus Streptosolen. 
plane, but enlarges more in a campanular form with five short 
rounded lobes, the front lobe bemg broadest ; it is however often 
4-lobed by the confluence of the two upper smaller segments ; 
the two lower stamens are not short, dilated, hemicyclical, and 
fixed in a ventricose swelling below the throat, but are here 
straight, slender and filiform, originating in the contracted base 
of the funnel-shaped tube and opposite the broader lobe of the 
border; the two upper filaments are also straight and nearly 
erect, although they are fixed im the mouth of the campanulate 
border, with one of the lobes of each anther almost abortive or 
dwarfish, as in Browallia ; all the filaments are terete, not greatly 
dilated, and although at first hairy, they become at last quite 
glabrous. The style resembles that of Browallia in being swollen 
at its summit, where it is hollow and corrugated into numerous 
transverse folds ; but the stigma is of an essentially different form, 
being suddenly expanded into two broad, compressed, auriculate, 
equal lobes, at first connivent, afterwards ringent, with a large 
opening in the sinus into the tubular summit of the style (and 
which in the living state is probably filled with mucous matter), 
thus approaching more to the form of the stigma of Petunia. 
The whole plant possesses much the habit of Stemodia suffruti- 
cosa, with which genus and with Pterostigma there exists some 
analogy in the form of the stamens and stigma. It will however 
constitute a genus belonging to the tribe Petunzee, connecting 
this group still more closely with the Salpiglossidee by Browallia. 
The name now proposed for this genus is derived from otpemrtos, 
tortus, cwdnv, tubus, because of the torsion of the lower portion 
of the tube of the corolla.
