 a position above the stigma in horizontal flowers.

Plethiandra Sahebii is known from a single individual brought 

 to the Singapore Botanic Gardens from Sarawak by a former em- 

 ployee — Mr. B. K. Saheb. It has been grown with the object of 

 determination. It has no horticultural value. 



Foliage of Plethiandra Sahebii, reduced to 1/3 

 Plethiandra Sahebii, as known, is a shrub about a metre high, 

 branching dichotomously from the ground upwards, so that from 

 four stems it ends in 16 branches bearing leaves. Between these 

 branchings there may be as many as six internodes, or only one. 

 In the axils of the old leaves it begins to flower, and from the 

 axillary bud continues to flower after the leaf has fallen, apparently 

 without limit of time, so that it is cauliflorous. As the leaves are 

 paired this results in two cushions of tissue opposite to each other 

 which continue producing flowers in fairly rapid succession; but of 

 these only one, or rarely two, is open at one time. Laterally at the 

 node from just above the level of the insertion of the leaves there 

 arise early, say, about the time when flowers are appearing, adven- 

 titious rootlets, and others follow just below the level of the insertion 

 of the leaves. If these rootlets find anchorage they become well 

 developed, and ultimately the effect is produced of the plant flower-
