338 ON HENRIQUEZTA VERTICILLATA. 



with very few seeds, are tlie same, as well as the general habit and 

 simple leaves. On the other hand, the semi-adherent calyx, with a per- 

 sisteut base and only four lobes, and the shape of the corolla, so much 

 more Bignoniaceous than that of Platycarpum, are marked generic dis- 

 tinctions. The adherent ovary in particular, analogous to that of Ges- 

 neriacem^ is as yet unique among Bignoniacea, It is to be regretted 

 that Mr. Spruce did not meet with the fidly formed fruit; but in its 

 young state it appears not to be compressed, like that of Tlaty- 

 carpum^ and to be more fleshy. The base of the calyx enlarges and 

 still adheres closely to it, but the apex of the fruit acquires a still 

 greater development, and the seed-bearing portion becomes almost 

 wholly exserted. The young seeds, two in each cell, showed already 

 an appearance of a winged margin, although possibly that may have 

 been the mere effect of desiccation in the single young fruit I possess.
