DR. B. SEEMANN ON THE CRESCENTIACEiE. 9 
I have not seen specimens of this species; and those seen by DeCandollc were without 
flowers and fruit. My reasons for placing it among the genuine Coleas were twofold : 
Because no true Bignonia has imparipinnate leaves a\ itli quite entire leaflets, nor flowers 
growing out of the old wood, as those of Colca discolor, according to Bojer, do : these 
three characters combined are only met with in Colca, and in no other Bignoniaceous or 
Crescent iaceous genus. As an additional reason, I may plead the close resemblance this 
species must bear to Colea purpurascens, rendering a specific distinction difficult. Both 
have hairy branches, leaves with 7 pairs, and leaflets more or less purplish underneath. 
Should a larger number of specimens come to hand, it may be found that there is no 
specific distinction between Colea piu°pu msec hs and C. discolor.

Colea hispidissima, Seem. MSS. 
Geogr. Distr. Ste. Marie, Madagascar (Boivinl n. 1820 in Herb. Par.). 
Differs from all known Coleas by its very hispid calyx and corolla. The leaves are 
probably, in the older branches, verticillate, as in all the other species of this group of the 
genus. 
6. Colea Mauritiana : arborea; ramis annularis glabris, foliis 3-1-nove verticillatis

2-3-jugis cum impari, foliolis subsessilibus obovato-cuneatis obtusis vel acuminatis 
coriaceis, racemis e caule ramisque ortis, calyce glabro, corolla (rosea) glabra vel 
tenuissime puberula, staminibus ovario styloque glabris, fructu oblongo acuminato 
verrucoso glabro (flavescente), seminibus ovali-oblongis. (v. sp. s.)

A tree, according to Bojer's MSS. in the Viennese Herbarium, and having Colea tetra- 
gona for its nearest ally. The leaflets of Bojer's specimen from Mauritius are quite obtuse.
