24 Dr. Jacx on Cyrtandracee, 
and distinct family near to Bignoniacee. The two first genera 
are numerous in the Malay islands ; and I may remark that, as 
far as my present observations extend, the Cyrtandre appear 
to prevail principally to the south of the Equator, and the Di- 
dymocarp? on the north, where it has even been found, according 
to the observations of Dr. Wallich, to extend to the alpine 
regions of Nepal. I shall proceed to give the characters by 
which this family and its genera are distinguished, and shall add 
descriptions of all the species that I have as a had an oppor- 
tunity of examining. 
CYRTANDRACEZÆ. 
Calyx monophyllus, divisus. 
Corolla monopetala, hypogyna, sæpius irregularis, 5-loba. 
Stamina. Filamenta 4, duo plerumque, nunc quatuor antheri- 
fera. Anthere biloculares, per paria connexæ, 
Ovarium disco glanduloso cinctum, biloculare vel pseudo-4-locu- 
lare, polysporum. Stylus simplex. Stigma bilamellosum 
v. bilobum. 
Capsula v. Bacca bilocularis, bivalvis, polysperma.  Dissepi- 
menta contraria, biloba, lobis revolutis seminiferis, loculos 
bipartientibus (inde pseudo-4-locularis). Semina nuda. 
Herbæ vel suffrutices. Folia simplicia, plerumque opposita, 
altero sæpe abortivo aut nano, exstipulata. Inflorescentia 
axillaris. 
In this family the flowers nearly resemble those of the Bigno- 
niaceæ, but have most frequently only two fertile stamina, and 
rarely exhibit any trace of a fifth. In fruit they are abun- 
dantly distinct; and the herbaceous stems, simple leaves, and 
axillary inflorescence, form important and striking differences of 
habit.
