24 Df' Jack on Cyrtandracea, 



and distinct family near to Bignoniacea. The two first genera 

 are numerous in the Malay islands ; and I may remark that, as 

 far as my present observations extend, the Cyrtandrcs appear 

 to prevail principally to the south of the Equator, and the Di- 

 dymocarpi 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 1 have as yet had an oppor- 

 tunity of examining. 



CYRTANDRACE^. 



Calyx monophyllus, divisus. • 



Corolla monopetala, hypogyna, saepius irregularis, 5-loba. 

 Stamina. Filamenta 4, duo plerumque, nunc quatuor antheri- 



fera. Anthera biloculares, per paria connexae. 

 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. 

 Herbae vel sufFrutices. Folia simplicia, plerumque opposita, 



aJtero saepe abortive aut nano, exstipulata. Injlorescentia 



axillaris. 



In this family the flowers nearly resemble those of the Bigno- 

 niacea, 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.
