Feucedanum] lxvii. umbelliferyE. 429 



uninterruptedly from above Sange in Serra de Alto Queta to 

 the bi-idge over the Coango stream, Welwitsch saw, among 

 several smaller ones, a tree at least 30 ft. high with rijje fruit ; 

 with reference to thk he remarked that botanically it would 

 have been a deadly sin to have this giant Umbellifer cut down 

 for the purpose of obtaining poles ; subsequently he cut down 

 near Bango in the forest of Quisucula a tree 18 ft. high for a 

 couple of poles, one of which reached Europe without being 

 destroyed by insects : on one occasion he saw his hammock negroes 

 collect the leaves not only for medical purposes but also to put them 

 on their shoulders under the bearing poles to prevent the chafing 

 of the skin. If no measures are taken to prevent the devastation 

 of the primaeval forests in the highlands of Angola, and if in the 

 future it is left to the self-intei-est and inconsiderate cupidity of the 

 ignorant colonists to burn down miles of the magnificent forests, 

 for the purpose of planting a very indifferent kind of coflTee or 

 bad cotton trees among the ashes, the possibility is that the noble 

 Calusange will soon become very rare and may before long quite 

 disappear from the country. It prefers a rich damp soil, and 

 appears to thrive best and to attain its greatest height in places 

 covered with the remains of leaves. 



This is the Umbellifer referred to by Welwitsch in Journ. Linn. 

 Soc. iii. p. 151 (18.59), of which the leaves form one of the most 

 famous remedies of the negroes, and of which the wood is used as timber. 



Var. haemantlmni (Welw. ms. in Herb.). 



Flowers atropurpureous, nearly blood-red. 



HuiLLA. — A slender shrub, about 3 ft. high, with 2 to 4 stems from 

 the base ; stems erect, simple or sparingly branched, the younger ones 

 purplish, transversely scarred ; stem-leaves very bright green, simply 

 impari-pinnate, 4-jugate ; petiole long, deep yellowish-reddish ; leaf- 

 lets oval or ovate-lanceolate, obtuse at the base, more or less acuminate 

 and protracted into an elongated seta, serrate-dentate on the margin, 

 with the teeth long- and subulate-setose, glabrous on both faces, pallid- 

 subglaucous beneath, very shortly petiolulate ; umbels terminal ; 

 flower-buds almost blood-red ; flowers polygamous ; peduncle with an 

 accessory involucre below the general involucre ; rays of the umbel 

 16 to 20 ; calyx-teeth distinct, narrowly deltoid, acute, persistent at 

 least on the young fruit ; petals when laid flat ovate-lanceolate with 

 a refuse acumen, appearing obovate and emarginate on account of the 

 inflexed acumen and impressed midrib ; disk depressed, nearly flat, 

 slightly or scarcely undulate on the margin ; ovary glaucous-purplish ; 

 stylopods small or rather the styles but little thickened at the base, in 

 the male flowers only punctiform or very short and without stigmas. 

 By a thicket on a sandy soil, near LopoUo, only one specimen seen ; fl. 

 without fr. Feb. 1860. No. 2519. 



2. P. muriculatum Welw, ms. in Herb. 



A rather scabrid erect perennial herb, with the habit of a 

 parsnip, 1 1 to 2 ft. high ; root cylindrical, succulent, stem 

 furrowed, somewhat branched in the upper half or two-thirds,

 pinnately trifoholate, petiolate, 2 to 3| in. long besides the petiole
