9. Solandree.—These form a very natural group, being all 
suffruticose, mostly subscandent plants, with large leaves and 
generally showy flowers. I have been enabled to obtaim very 
satisfactory elements of the little-known genera Juanulloa and 
Marckea, besides those of two new genera. They bear a some- 
what similar position among the Afropacee that the Metterni- 
chiee hold among the Solanacee, and the analogy in the strue- 
ture of the seeds of Marckea and Metternichia is sufficiently re- 
markable. 
10. Brunsfelsiee.—This group, consisting of some of the pin 
placed by Mr. Bentham in his Salpiglossidee, is distinguishable 
from that tribe as above limited by the absence of the remark- 
able dilatation of the stigma : it will comprise the genera Bruns- 
felsia, Franciscea and Heteranthia: the latter much resembles 
Browallia in its habit, but it accords with the two former genera 
in the structure of its anthers, which are unilocular, and curved 
inthe shape of a horseshoe round a fleshy globular connective, 
that m great part enters into and nearly fills the cavity of the 
cell, as in the Verbascea. I have here considered Franciscea as 
distinct from Brunsfelsia, which Mr. Bentham (in DeCand. Prodr, 
x. p. 198) combined together under one genus. In Brunsfelsia 
however the corolla is always of a yellowish colour, the tube is 
considerably longer and narrower in proportion, and the fruit 
consists of a large fleshy drupe inclosmg a putamen which is 
quite indehiscent. In Franciscea the flowers are always of a 
purplish or violet colour, with a much shorter tube and an 
oblique rotate border: the fruit is generally capsular, and rarely 
somewhat baccate ; but when this occurs, I have noticed in the 
dried specimens, that as the fleshy sarcocarp covering the puta- 
men dries into the form of a coriaceous integument, both split 
into four divisions at the apex, in a valvular form, as in the eap- 
sular species. . In Brunsfelsia the style is very long and slender, 
quite erect at the apex, and terminated by a small clavate stigma _ 
which is bilobed, its equal concave lobes being filled with a ball 
of grumous matter. In Franciscea the style is considerably en- 
larged and incurved at its summit, which is terminated by a 
much larger bilobed gaping stigma, the lower lobe being some- 
what smaller, and it exhibits in its sinus a globe of viscous mat- 
ter, seen only in the living state. In Heterantiia the style is 
far exserted, and is terminated at its slender and somewhat in- 
curved apex by an almost obsolete fistulose stigma. The spe- 
cies of Brunsfelsia attain the size of large trees, 20 feet in height, 
while on the contrary those of Franciscea do not exceed the size 
of bushes, which are seldom more than 3 or 4 feet high. Hete- 
ranthia, on the other hand, is a small repent perennial plant, 
with. short ascending branches, terminated by a racemose inflo- 
rescence.
