 farther southwards. 



Zygophyllaccae.

Port Hed land (No. 1155,3. Nov. 1914). A decumbent yellow- 

 flowered herb. 



As I have no access to the description of T. Forrestii 

 F. v. Müll, (in Wing's S. Sc. Rec. Nov. 1885), and as my only 

 specimen has no fruit, 1 have given it under the old collective 

 name T. cistoldes L. 



Euphorbiaceæ. 



Excoecaria agallocha L. Sp. pi. ed. 2 (1763) 1451; Benth. Fl.

Derby, a small tree in the mangrove (No. 1164, 7. Nov. 1914). 



Amongst the Avicennia's which make up the main part of 

 the mangrove at Derby near the jetty, single specimens of a 

 small tree with dark green and shining leaves occurred. As I only 

 could get specimens without any flower and fruit, I was not able 

 to refer the plant to its proper place. But at my request, Pro- 

 fessor V. A. Poulsen of Copenhagen examined the structure of 

 the leaves and suggested that it might be a species of Excoecaria, 

 owing to its extrafloral glands at the base of the leaf-blade and 

 to the milk vessels. This led me to identify it as a variety of 

 E. agallocha answering well to the var. ovalis (Endl.) Müll. Arg. 

 (D. C. Prodr. XV. 2 (1866) 1221), according to the description of 

 this given by Pax (1. c): Folia suborbicularia vel orbiculari-obo- 

 vata, apice rotundato-obtusa. 



This variety — as well as the main species — are both known
