GoLUNGO Alto. — A robust evergreen shrub, climbing up the tallest 

 trees and ornamenting their crowns with innumerable flowers and 

 filling the whole vicinity with very sweet fragrance ; stems usually 

 4 to 5 ft. in diameter at their base ; branchlets and even the thicker 

 branches glossy with a grass-green bark, smooth, the young ones 

 occasionally striate, the older ones reflexed-arched ; leaves thinly 

 coriaceous, glossy, flat, not revolute at the margin ; flowers variegated 

 with white and rose-colour ; calyx 5-sepalous, with three shorter 

 sepals and two large brilliant -white lateral ones ; petals 3, the front 

 one galeate-folded in the form of a keel, investing the sexual organs, 

 white, rose-coloured at the apex ; the two back petals broadly linear, 

 fleshy, straight, rose-coloured at the base, at the apex brilliantly 

 sulphur-coloured and truncate, shorter than the front one and over- 

 lying it in an imbricate manner, quite patent in full flower ; stamens 

 monadelphous, 8, ascending, combined into a vertically compressed 

 tube cleft in front ; filaments white, equal in height, free at the 

 apex ; anthers erectly fixed at the apex of the filaments, yellow, 

 apparently opening longitudinally with 2 or 3 pores ; ovary obcordate, 

 in the centre of the thick turgid annular disk, terminating in the 

 violet-coloured ascending style ; stigma shortly clavate-capitate, green, 

 papillose-viscid, usually bearded with the closely adhering and dried

 the mountains of Serra de Alta Queta ; fl. from 19 Mar. to June, fr. 

 from May to Sept. 1855-56, occasionally. No. 994. A stout shrub,

Var. jS platyphylla Welw. ms. in Herb. A scandent shrub, 6 to 7 

 ft. high ; the upper part of the stem as well as the branches and 

 branchlets purple ; leaves broadly ovate, almost subcordate, thinly 

 coriaceous, constantly but narrowly revolute on the margin, brightly 

 glossy above, a little paler beneath. 



GoLUNGO Alto. — In shady little woods, near N-d^le (N-della), 

 rather rare ; fl. Feb. 1856. No. 995. 



The structure of the stem in this creeper is extremely curious, and 

 it appears to be a character in the genus ; for Dr. Kirk observed the 

 same arrangement of the vascular bundles in the wood of another 

 species from the Zambesi country.
