Easily distinguished from C. asiatica, Brongn., and C. javanica, 

 Miq., by having a much longer peduncle. 



Small tree. Leaves alternate membranaceous, ovate-acuminate 

 or subacuminate, margin entire or somewhat undulate, when fully 

 matured glabrous above and strigose pubescent below, especially 

 on the veins. Lamina 3-4 ins. long, \h-2 ins. broad ; petiole 

 generally about \ in. long. 



Flowers in axillary cymes. Peduncles much longer than in 

 C. asiatica., Brongn.. being from H-H in., strigosely hairy, as are 

 also the pedicels. Calyx pubescent externally, lobes ovate, acute, 

 with internal keel. Petals shorter than the sepals, nearly 1 line 

 long, rather remote from each other, concave. Stamens about same 

 length as petals. Style erect, stigmas 3. Ovary immersed in the 

 disk semi -inferior. Fruit not seen. 



The genus Marcorella, Necker, Elem., ii, p. 122 (1790), has been 

 placed by Mr. Jackson in the Index Kewensis as synonymous with 

 Colubrina. It is considerably earlier, but I have seen no authentic 

 material of this.
