DR. B. SEEMANN ON THE CRESCENTIACE^. 9 



I have not seen specimens of this species ; and those seen by DeCandoUe were without 

 flowers and fruit. My reasons for placing it among the genuine Coleas were twofold : — 

 Because no true Blgnonia has imparipinnate leaves with quite entire leaflets, nor flowers 

 growing out of the old wood, as those of Colea discolor, according to Bojer, do : these 

 three characters combined are only met with in Colea, and in no other Bignoniaceous or 

 Crescentiaceous genus. As an additional reason, I may plead the close resemblance this 

 species must bear to Colea ptirpiirascens, rendering a specific distinction difiicult. 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 imrpurascens and C. discolor. 



5. Colea hispidissima ; fruticosa ?, ramis subteretibus glabris, foliis oppositis (v. verti- 



cillatis ?) 4-5-jugis cum imparl, foliolis longe petiolulatis obovato-oblongis breviter 

 acuminatis, racemis abbreviatis e caule ramisque ortis, calyce coroUaque extus pilis 

 ferrugineis hispidissimis, corolla (alliida ?) intus ovario styloque hispidis, staminibus 

 glabris, fructu .... (v. sp. s.) 



Colea hispidissima, Seena. MSS. 



Geogr. Distr. Ste. Marie, Madagascar {Boivin\ 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 Mauritlana; arborea; ramis angulatis glabris, foUis 3-4-nove verticillatis 



2-3-jugis cum impari, foliolis subsessilibus obovato-cvxneatis obtusis vel acuminatis 

 coriaceis, racemis e caule ramisque ortis, calyce glabro, corolla (rosea) glabra vel 

 tenuissime puberula, staminibus ovario styloque glabris, fructu oblongo acuminate 

 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. 



7. Colea tetragona; fruticosa; ramis acute 4-7-gonis, glabris, foliis 4-7-nove ver- 



ticillatis 5-9-jugis cum impari, foliolis brevi petiolulatis oblongis obtusis basi in- 

 sequalibus subcuneatis coriaceis, racemis e caule ramisque ortis abbreviatis, calyce 

 glabro, corolla (rosea) extus puberula, ovario . . ., fructu ... (v. sp. s.)
