Anubias] xx. aroide^. 89 



GoLUNGo Alto. — A stiff terrestrial herb, with creeping rhizome 

 ultimately becoming almost woody. Leaves very polymorphic. Shady 

 rocky places in primaeval woods at a place called Fonte de Quibolo, 

 March and April 18r)G. Nos. 237, 238. 



Cazex(;o. — A small subcaulescent plant with thick almost woody 

 rhizome, caudex very short, marked with semicircular leaf-scars, and 

 bearing at the top 4 to G leaves, which are long-stalked, ovate-lanceo- 

 late, more rarely slightly cordate at the base, hard and leathery, 

 shining above, paler beneath, penninerved, the long-sheathed petiole 

 swollen and bent a little below the blade. Scape lateral, arcuately 

 ascending ; spathe convolute below gaping a little at the apex, fleshy, 

 brittle, rather hard, green. Spadix ovate-cylindrical, bearing from 

 base to middle the slightly separated green ovate ovaries crowned with 

 a peltate discoid stigma, and from the middle to the obtuse apex the 

 anthers ; sterile flowers absent. Anthers about S to 10, vertical, with 

 a thick, peltately truncate connective, unilocular (V) dehiscing length- 

 wise. Connectives very closely crowded, whitish, anthers snow-white 

 adnate to the connective in a whorl. Very shady primitive woods 

 by streamlets in the mountains called Muxaulo, plentiful, but not 

 often flowering. In fl. beginning of Jan. 1855. No. 236. A unique 

 specimen. 



Some confusion has arisen in regard to the numbers 236 to 238. 

 Welwitsch, who submitted his material to Schott, names all three 

 A.Afzelli Schott. Engler in DC. Mon. Phan., I.e., founded a new species, 

 A. heterophil/ 1<(, on "Welwitsch No. 236 to 238" from Golungo Alto. 

 Subsequently in Bot. Jahrb., I.e., he quotes for ^-1. Afzdii Angola 

 Welwitsch No. 237 in herb. Schweinf urth, No. 238 in herb. De Candolle, 

 and for A. hiteropIiijUa Angola, Golungo Alto, Welwitsch No. 236. 

 Engler accordingly recognises two species in Angola, ..-l . Af~el/i Nos. 237, 

 238, and .1. heternjihi/lla No. 236- There is no evidence that he saw 

 the true Welwitsch No. 236, as Mr. Hiern informs me that no dupli- 

 cates were distributed. The specimens of 237 and 238 in the British 

 Museum were all collected in the same locality and at the same time 

 in Golungo Alto, and are obviously the same, and conform to Engler's 

 description of .1. heterophylla. They are both in fruit, and may be 

 distinguished from A. Afzdii by the shorter peduncle, which is about 

 equal in length to the leaf-stalk.

 doubt.

Prince's Island.— Plentiful in damp shady places at the foot of the 

 mountain (Pico de Papagaio). In fl. Sept. 1^53. No. 222. This 

 pretty little Aroid is very common in the damp forests, and occurs up 

 to 1^000 ft. on the Pico de Papagaio. It may, however, have been intro- 

 duced from Brazil with trees, many of which, e.fj. Persed gndissima, 

 Pitangueira {Kuf/enid. ?//////<;/•«), etc., were in very early times transplanted 

 from Brazil to St. Thomas and Prince's Island and have succeeded well.
