XXVI. LINACBiE. 



The indigenous Linacea? consist of three species of Hugonia and 

 an Eryth'oxylon. The species of Hugonia are fine shrubby climbers 

 with a very peculiar habit, sometimes climbing on trees, at other 

 times covering with dense bushes the slopes of rocks ; their yellow 

 flowers look somewhat like those of Linum jlavum L., but their 

 glossy foliage consists of large coriaceous and evergreen leaves. 

 The Erythroxylon which is met with in Pungo Andongo has its 

 wood entirely white, whereas the species of this genus usually 

 have the wood red. (See Welw. Apont. p. 566 under n. 161 and 

 p. 561 under n. 146.) 



Linum usitatissimum L. Sp. PI. edit. 1, p. 277 (1753) ; Oliv. Fl. 

 Trop. Afr. i. p. 269. Huilla. — Cultivated for the sake of its fibre and 

 seeds, but rather rarely ; fr. May 1860. No. 1583. 



The axile margins of the carpels are glabrous, and the capsule but 

 little exceeds the calyx ; the specimens therefore do not belong to the 

 variety which was Linum humile Miller. Welwitsch, Apont. p. 566 

 under n. 161, states that this species is cultivated, although in limited 

 quantity, in the neighbourhood of Pungo Andongo, chiefly on account 

 of the application of its oily seeds for poultices.
