MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [Vol. 8, No. 3 



Plateau, plentiful in forest regrowths, tree or shrub 2-5 m. high, producing a pro- 

 fusion of flowers, very showy species, flowers yellow, unripe fruit red, 1820 m., 

 June 25, 1946, 16428. Highlands of Tropical and South Africa, and the Mascarene 

 Islands. 



Good (Jour. Bot. 65: 329. 1927) considers that the plant from the African main- 

 land is distinct from hi. lanceolatum Lam., which was described from the Isle of 

 Bourbon, and accordingly refers the former to H. leucoptychodes Steud. ex A. 

 Rich. After careful examination of the now much larger collections of the African 

 plant, I consider that it is conspecific with Lamarck's species. 



Harungana madagascariensis Poir. Encyc. 6: 314. 1804. 

 Arungana paniculata Pers. Syn. 2: 91. 1807. 



Haronga madagascariensis (Poir.) Choisy, Prodr. Mon. Hyperic. 34. 1821. 



Haronga paniculata (Pers.) Lodd. ex Steud. Nom. Bot. ed. 2. 1: 722, in synon. 1841. 



North Nyasa District: Nchena-chena, frequent on banks of streams in Brachy- 

 stegia woodland, tree 5-8 m., leaves greyish below, dull green above, fruit 

 yellow-green, native name (Chinyanja) mpefu, 1340 m., Aug. 21, 1946, 17379. 

 Tropical Africa, Madagascar, and the Mascarene Islands. 



GUTTIFERAE 17 



Garcinia huillensis Welw. ex Oliv. Fl. Trop. Afr. 1: 167. 1868. 

 Garcinia buchanani Bak. Kew Bull. 1894: 354. 1894. 

 Garcinia gossweileri Engl. Bot. Jahrb. 40: 571. 1908. 



Kota-kota District: Chia area, on bank of water-hole on dry lake-plain, ? tree 

 15 m. high, flowers yellow, 480 m., Sept. 5, 1946, 17543. Portuguese East Africa, 

 Nyasaland and southern Tanganyika to Angola and S. Rhodesia. 



G. huillensis is very vatiable in shape and width of leaf. Staner (Bull. Jard. 

 Bot. Brux. 13: 132. 1934) separates G. buchanani Bak. from it chiefly on account 

 of the latter species having only two sepals. Careful examination of the type 

 specimen of G. buchanani shows four sepals on the only flower-bud that there is 

 on the specimen. Most of the sepals and petals of the other Flowers have fallen, 

 but one flower shows four petals and two sepals, the other two sepals having 

 already dropped. I therefore reduce C. buchanani to the synonymy of G. huillensis. 



DIPTEROCARPACEAE" 



Monotes africanus A.DC. in DC. Prodr. 16 2 : 624. 1868, emend. H. Bancroft in Car- 

 risso, Consp. Fl. Angol. 1: 136. 1937. 



Kota-kota District: Nchisi Mountain, frequent in Brachystegia woodland, tree 

 to 8 m. tall and to 20 cm. diameter, leaves stiff, greyish below, native name 

 (Chinyzfnja) chikaka, 1400 m., Aug. 5, 1946, 17133. Nyasaland to Angola. 



This is a very variable species which in some of its forms approaches M. 

 rufotomentosus Gilg. 



Monotes rufotomentosus Gilg, Bot. Jahrb. 28: 138. 1900. 



North Nyasa District: Nchena-chena, frequent in Brachystegia woodland, tree 

 3-6 m. high, native name (Chinyanja) chikakata, 1340 m., Aug. 21, 1946, 17380. 

 Nyasaland. 



H. Bancroft, who has made an intensive study of the genus Monotes wrote in 

 1938: "The indications at present available are that M. rufotomentos&e Gilg is a 

 series or plexus of hybrid forms between M. africanus and M. engleri. There are 

 naturally specimens which approach one or other of these species very nearly."
