Landolphice Species . 
“West Coast ,J (African) Caoutchouc. 
Landolphia Owariensis ,. Pal. de Beauv. Pl. Owar et Benin, I., 
p. 54. t. 34., D.C. Prod, viii., p. 320. 
Synonym . — Pcederia Owariensis , Spreng., Sys. i., p. 669. 
Vernacular Name. — Licongue or lAcomgue (sing.). 
Macomgue (plural form) (Plate 4). 
Geographic Distribution. — Dr. Welwitsch remarks (in MS. 
to Collins) that this species “ first discovered by Palisot 
de Beauvais in Owar and Benin, and afterwards by Don 
in Sierra Leone, I have encountered rather frequently 
in several of the highland districts of Angola, and con- 
sequently the habitat of this plant may be stated as 
extending from 10° lat. N. to 10° lat. S. on the tropical 
coasts of West Africa.” 
Remarks . — Dr. Welwitsch (1. c.) describes it as a “large 
climbing plant, four to six inches in diameter, at a 
height of two or three feet from the ground. Prom 
this point it is divided into several long thin branches 
which are again and again divided, climbing along the 
stems and larger branches of neighbouring trees, to 
which they fix themselves by means of most tenacious 
spirally-twisted tendrils formed out of the indurated 
flower-stalks after the ripe fruit has fallen off. The 
fruit is about the shape of a middle-sized orange, con- 
taining under a hard, nearly woody, reddish brown 
shell, a sweet, rather acidulous pulp, which is eaten by 
the natives.”

L.florida , Benth. in Pl. Nigritiana, p. 444. 
Vernacular Name. — “ aboh ” or “ abo * (fruits). 
Geographic Distribution. — Dr. Welwitsch remarks (1. c.) 
this species is found “ rather frequent in most of the 
primeval forests of inner Angola, where, at an elevation 
of 1,500 to 2,500 feet,* I often met with this beautiful 
climber, and gratified myself with its sweet acidulous 
fruit, though not less so with the beauty and marvellous 
abundance of its large snow-white and jasamin-scented 
flowers.”
