This is the rather thick tree, 30 ft. high, with large fruit and edible 

 seed, noticed by J. R. T. Vogel by the river Niger, IG Sept. 1841, and 

 called by the Kroomen " Oqua."' See Niger Flora, pp. 67. 68, 525 

 (1849). In the island of St. Thomas, the name " Oca " or " Oqua," is 

 used to designate Ceiha Caiie<irt<i Medic, ante, pp. 80, 81.

GoLUNGO Alto. — A shrub or low tree, 4 to 8 ft. high, erect, spar- 

 ingly but really lactescent ; stem branching a little above the base ; 

 branches sparse, virgate, patent, elongated, slender ; leaves large, 

 elliptical, long-acuminate, slightly rough, evergreen, subcoriaceous, 

 dark green and glossy, (the older ones opaque) above, pale green 

 beneath ; receptacles on erect axillary stalks, solitary or 2 or 3 

 together, ob-pyramidal, embedded in pulp, the young ones capituliform, 

 involucrate with 5 to 7 broadly ovate acuminate green scales, which 

 are fringed on the red margin and converge adpressedly at the top of 

 the capitulum ; the scales at the time of the flowering mostly deciduous, 

 one or two afterwards conspicuous at the outer face of the receptacle, 

 and the top of the capitulum spreading into a circular somewhat flat 

 whitish fleshy torus, the margin more or less unequally erose-undulate 

 or crenulate. The male flowers very numerous, at first 5 of them 

 appearing around the female flower, afterwards always in a greater 

 number, and finally covering the whole plane of the receptacle, each of 

 them consisting of a very short cylindrical tube, entire at the mouth,. 

 from the bottom of which rises the single whitish somewhat fleshy 

 stamen ; anther didymous, whitish, quickly turning dusky. The 

 female flower solitary, central, consisting of an ovoid ovary, with a 

 style bifid at the apex and only the flattened lobes exserted, sessile at 

 the base of the receptacle, and rising through the cavity of the fleshy 

 torus to its surface. In very dense exceedingly shady primitive 

 forests, preferring the neighbourhood of streams, especially about the 

 Capopa cataract, between Sange and N-delle, plentiful : fl. abundant 

 throughout the year, fr. only seen on one branch, 4 Oct. 1854 and 

 June and Aug. 1855 and 1856. No. 2594. 



This is the plant mentioned by Welwitsch in Journ. Linn. Soc. iii. 

 p. 151 (185'.l) as a genus nearly related to Dorstenia and as a large 

 woody shrub 4 ft. high, in general habit like a fig, but with the 

 receptacles obconic truncate and open, just as in Kowria. Lichen 

 n. 477 grew on the leaves of this shrub at Capopa in the spring and 

 summer of 1855 ; and the fungus n. 508 about its branchlets. 



Brwiuichki afrlcana Welw. herb. no. 1754 {(tnte, pp. 905, 906) grew 

 in company with the Trymatoan-xus ; also a scarlet-flowered Ochnacea 

 (cf. Ochut, meuibranacea Oliv., var. ruhescens ; ante, p. 120), and Com- 

 bretacete with velvety fruit (cf. Coiahretum paradoxum Welw. herb, 

 no. 4385, itnte, p. 350). 



It is, perhaps, the " Matomba," which Welwitsch in his mss. says- 

 is the name of a small or middle-sized tree, belonging to this group of 

 plants, and that with it the negroes in the district of Cazengo make 

 very strong cords. In Barra do Dande the name " Matombe " is used 

 for Raphia textiUs Welw.
