places in Eastern Queta ; in flower-bud, Jan. 1856. No. 4659. In the 

 -very dense woods of the mountains of Serra de Alto Queta, in Mata de 

 Mangue ; fl. end of May 1856. No. 4660. Sange ; in young fl. and fr.

The following must be compared with Dichapetalwm : — 



Golungo Alto. — A bush 5 to 8 ft. high ; trunk straight, slender, 

 erect, 1 to 1J in. thick ; branches spreading, subscandent ; flower-buds 

 whitish, silky. In the dense primitive forests of the mountains of 

 Queta Central, at Zengas de Queta ; without fl. beginning of August 

 1858. No. 4668. 



The next five Nos., which are closely related among themselves, 

 are very doubtfully placed in this genus : — 



Golungo Alto. — A patently branched bush ; leaves sub-membra- 

 nous or very thinly coriaceous, wavy at the margin in the living state, 

 axillary buds red. In the thickets of the mountains of Alto Queta ; 

 without fl. June 1856. No. 542. A shrub, 1£ to 3 ft. high, much 

 branched from the base, apparently a secondary shoot of a larger 

 perhaps scandent shrub ; habit like Combretum, but the leaves are 

 alternate. On the sides of the Ambaca road near Camilungo ; without 

 fl. Nov. 1855. No. 3018. A low shrub with ferruginous-hirsute almost 

 horizontal branches. By thickets and the sides of roads between Sange 

 and Ponte de Felix Simoes ; without fl. August 1855. No. 3019. 

 Queta, without fl. 1 August 1856. No. 4696. A low shrub growing in 

 a caespitose manner, probably the radical shoot of a burnt tree. On 

 the sides of the road between Cambondo and Trombeta ; without fl. 

 June 1855. No. 4697. 



XXXVI. OLACINE^E. 



The Olacinese of Angola are shrubs or small trees, but little 

 conspicuous, and are met with especially in the dense woods of 

 the hilly regions (Welw. Apont. p. 560, n. 141). Welwitsch 

 observed that in several Olacinese examined by him the style is 

 subexcentric and curved, as for example in Apodytes dimidiata 

 E. Mey.
