8 DR. B. SEEMANN ON THE CRESCENTIACE^. 



Geogr. Distr. Common throughout Madagascar [Commerson ! in Herb. Par., et Juss. ! Boje?- !) ; Mau- 

 ritius [Sieber ! in Herb. Vindob.). 

 This is the only species of Colea as yet cultivated in our gardens. It is better known 

 than aU the others ; and we are therefore enabled to settle its synonymy with tolerable 

 accuracy. I have seen, at Paris, Commerson' s specimens upon which DeCandoUe founded 

 his Colea ? CommersonU, and consider them to be in every respect identical with C. flori- 

 bimda. Why DeCandolle placed C. CommersonU among the species with terminal flowers 

 is diificult to say, since some of the specimens prove that the racemes grow out of the 

 old wood. Sieber's n. 284 from Mauritius, upon which DeCandolle founded his C. cauli- 

 flora, I have examined in the Vienna Herbarium, and I find that it cannot be specifically 

 separated from C. Jloribimda. 



2. Colea Setchellarum ; arbuscula; ramis angulatis giabris, foliis 3- 4i-nove verticillatis 



4-5-jugis cum imparl, foliolis petiolulatis obovato-oblongis obtusis, basi attenuatis, 

 coriaceis utrinque giabris, racemis elongatis e caule ramisque ortis, calyce glabro, 

 coroUa extus glabra, intus villoso-pubescente, ovario styloque glabro, fructu ....

 Geogr. Distr. Isle of Mahe {Bernier\, n. 38). 



This new species has the habit of Colea jloribunda, Boj. It is, according to Bernier, 

 from 20-25 feet high. Leaves 1-1| foot long ; leaflets 4-5 inches long and 1^-2 inches 

 broad. Racemes often 8 inches, and corolla about 1 inch long. At once distinguished 

 from C. jloribunda by its very long racemes and its (outside) glabrous corolla. 



3. Colea purpurascens ; . . . . , ramis angulatis pubescentibus, foliis 3-7-no verticil- 



latis 7-10-jugis cum imparl, foliolis petiolulatis ovato-oblongis longe acuminatis basi 

 attenuatis, petiolis, petiolulis nervisque inferioribus purpurascentibus, racemis abbre- 

 viatis e caule ramisque ortis, calyce glabro, corolla extus velutino-scabrida, stylo 

 superne viUoso, fructu .... (v. sp. s.) 

 Colea jiurpurascens. Seem. MSS. in Herb. Paris. 

 Geogr. Distr. Ste. Marie de Madagascar {Boivin\) ; Nossi-be (Boivin !). 



Has the habit of Colea Jloribunda, but diifers in the pubescent branches, and pseudo- 

 stipules, the pui'plish tinge of the petioles, petiolules, and veins of the under side of the 

 leaflets, as vrell as in its villose style. It flowers, according to Boivin, from November 

 to January. 



4. Colea discolor ; fruticosa ; ramis (angulatis ?) apice hirsutis ; foliis (verticillatis ?) 



7-jugis cum imparl, foHolis brevi-petiolulatis oblongo-lanceolatis obtuse acuminatis 

 subtus purpureis, racemis e caule ramisque ortis, calyce . . . , coroUa . . . , ovario 

 . . . , stylo . . . , fructu . . .
