330 xlviii. dboserace^i. [Drosera 



bution of this species is much wider than that of the others; 

 farther north, several degrees nearer the equator, this species 

 occurs in the coast region, but very rarely ; a small stunted form 

 was discovered in the swampy forest near Quizembo in the Ambriz 

 district. 



All the species found are probably perennial, although D. indica 

 L. has quite the appearance of an annual plant. Numerous small 

 bulbs or tubercles are developed just below the surface of the 

 ground, and under the shelter of Scytonemata and mosses seem to 

 produce the future flowering plants ; a similar condition occurs- 

 in the case of several Scrophulariacese, TJtricularise, etc.
