The longest branch measures 3 ft. below the terminal in- 

 florescence; the lower part is covered with a thin, papery, brownish, 

 easily peeling bark. The largest leaves have a blade 3 in. in length 

 by 2 in breadtli, with a slender petiole of 1^ in. On the branchlets 

 below the inflorescence they are about 1 in. long by ^ in. broad. 

 The number of large bright-coloured flowers gives the inflorescence 

 a striking appearance. The individual flowers are almost sessile, 

 forming crowded cymes, which again are almost sessile in the axils 

 of the bracts. The bracteoles are linear-lanceolate, slightly hairy, 

 and ^ in. or more in length. The calyx is 4 lines long ; the corolla- 

 tube is nearly ^ in., the slender erect portion below the constriction 



4 lines ; the posterior lip has a truncate apex, and is | in. long by 



5 lines broad ; it arches over the slightly protruding stigma and 

 anthers ; the spreading lower lip is f in. long, the lobes 4 lines 

 broad. The stamens are nearly 1 in. long; of the oval oblong 

 anthers, the upper is placed transversely on the top of the filament, 

 the lower is fixed to the side at almost a right angle with the upper ; 

 they are 1^ lines long; the delicate spur is less than a quarter their 

 length. The pollen-grain is banded. The rather slender ovary is 

 1^ lines long, the filiform style 1 in. The two ovules in each 

 loculus are alternately superposed. 



Near the S. African D. adhatodoides E. Mey., but has rather 

 larger flowers, difl'ering in their much longer calyx-teeth, and the 

 shape of the corolla, especially in the truncate posterior lip, and the 

 larger more oblong lobes of the anterior, and also in the spurred 

 anthers. 



Euphorbia tetracantha, sp. nov. Hum ills, fruticosa, glau- 

 cescens, ramis 4-angulatis, pulvinis decurrentibus aculeis quaternis 

 horridis ; cymis ramorum apice binis axillaris oppositis ; bracteis 

 minutis ovatis ; cyathiis 3, sessilibus, externe breviter papillosis, 

 mediana ^ breviter et late campanulata, lateralibus cyathiformibus 

 flore centrali ? , floribus $ circamdatis ; involucris segmentis 5 

 brevibus subfimbriatis, glandulis in annulum 5-undulatum crassi- 

 usculum coalitis ; floribus S squamis apice fimbriatis interspersis ; 

 ovario pedicellato, stigmatibus tribus indivisis coronata.

6 in. high. The spreading branches springing from a short 

 stout woody stem, and subfleshy (2 lines thick). Their four angles 

 are determined by the hard decurrent pulvini, each of which bears 

 four stifi" projecting sharply pointed spines, two lower longer ones 

 reaching 10 lines, and two upper slenderer and shorter less than 

 half the length. The cyathia are borne in opposite sessile cymes, 

 three in each. The central, male, is slightly shorter and broader 

 than the two lateral (scarcely 1 line long by more than 1 line broad
