microscopic buds, found in the axils of many of the foliage 

 leaves (Widmer, p. 10). 



I have not been able to prove the presence of dimorphic 

 flowers in this species (see E. Warming 1886 a, p. 24). The 

 length of the style varies only slightly, the majority of the 

 flowers examined showing the 

 stigma placed as in fig. 2, a. 

 Self-pollination may occur, as 

 the pollen and the stigma 

 in the same flower seem 

 to be fully developed at the 

 same time. In Flora Danica 

 the stigma is figured as ex- 

 tending a trifle above the 

 anthers. The corolla is 5 — 8 

 mm. in diameter, the colour 

 being white, with a yellowish 

 ring in the throat. (Fig 2.) 



The peduncle increases 

 in length after flowering, as 

 in the case of Pr. stricta. 



Anatomy. A transverse 

 section of the young primary 

 root (fig. 3, A) shows the cen- 

 tral cylinder to be very thin, 

 only \ of the diameter of the 

 root; the fourth layer of the 

 cortex seems to be in process 

 of formation. The primary 

 root is diarch. Fig. 3, B, 

 shows the central cylinder 



with the endodermis of a very young adventitious root. 

 The cells of the cortex are filled with starch, except the 

 outermost layer, which functions as an exodermis; this is
