 aceous, with prominent pinnate venation.' That of 



PLUMERIA ACU- 

 TIFOLIA (fig. 26) 

 is the same ex- 

 cept that it is 

 'elliptic acute at 

 both ends ' in- 

 stead of 'oblong', 

 etc. The leaves 

 of ERYTHRINA

 with pulvinus 

 and two large 

 glands at the 

 base, broadly

 tire, glabrous'. 



Combinations 

 are used to de-

 mediate types, 



thus a broad lanceolate leaf would be called ovate - 

 lanceolate ', and a narrow lanceolate might be linear- 

 lanceolate ' (fig. 38).

 or obtuse it might not be mentioned at all. But it 

 is always necessary to name the position, nature,
