MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [Vol. 8, No. 5 



Further material. of this is desired. What are probably o* plants of this, though 

 the specimens are poor, were collected in July 1896 on the Masuku Plateau, Nya- 

 saland, at 1980-2130 m. alt. by A. Whyte. 



BEGONIACEAE 



Begonia ? sp. nov. aff. sutherlandi Hook. f. 



Zomba District: Zomba Plateau, one plant on a moist shady rock in rain- 

 forest, herb 90 cm. high, one reddish stem erect from a large tuberous base, pet- 

 ioles and leaf-nerves red, flower pale pink, 1500 m., June 7, 1946, 16322*, 



A very poor specimen collected by A. Whyte in December 1894 between 1220 

 and 1830 m. on Mount Malosa, Nyasaland, is probably the same as Mr. Brass* 

 specimen. 



CACTACEAE 



Rhipsalis cassutha Gaertn. Fruct. 1: 13 7„ 1788; Britt. & Rose, Cactaceae 4: 225. 

 1923. 



Cholo District: Cholo Mountain, common epiphyte, high on rain-forest trees, 

 shrub, branches pendent, numerous, fleshy, up to about 80 cm. long, 1350 m., 

 Sept. 20, 1946, 17676; ibid., common, high epiphyte in rain-forest, shrub, branches 

 to 80 cm. long, cylindrical, pendent, flowers 7 mm. in diameter when fully ex- 

 panded, pale green, 1200 m., Sept. 26, 1946, 17824. Nswadzi R.iver, epiphytic on 

 relict rain-forest trees of river-bank, shrub, branches to 1 m. long, pendent, cy- 

 lindrical, green, flowers about 10 mm. in diameter, rotate, greenish-white, fruit 

 unripe, 840 m., Sept. 27, 1946, 17842. Widespread in the tropics of Africa and 

 America, also found in Madagascar, Mauritius, Seychelles, and Ceylon. 



FICOIDACEAE 



Glinus oppositifolius (L.) A. DC. Bull. Herb. Boiss. II. 1: 559. 1901. 

 Mollugo oppositifolia L. Sp. PI. 89. 1753. 

 Mollugo spergula L. Syst. Nat. ed. 10. 881.' 1759. 



Chikwawa District: Lower Mwanza River, on sandy beaches, 180 m., Oct. 3, 

 1946, s. n. Widespread in the tropics of the Old World. 



A small piece of this plant found mixed with 17931 (Gisekia africana var. 

 pedunculata). 



Gisekia africana (Lour.) Kuntze var. pedunculata (Oliv.) Brenan, comb. nov. 



Gisekia miltus Fenzl var. pedunculata Oliv. Fl. Trop. Afr. 2: 594o 1871. 



Chikwawa District: Lower Mwanza River, common on sandy beaches, prostrate 

 herb, lowers yellow, 180 m., Oct. 3, 1946, 17931; ibid., common on sandy 

 beaches, prostrate herb, flowers yellowish-white, 180 m., Oct. 4, 1946, 17975. 

 Distribution at present doubtful, the species probably widespread in southern 

 Africa. 



I prefer to adopt Oliver's view of the limits of this species rather than those 

 of Burtt Davy (Man. Fl. PI. Transv. 1: 153. 1926); Loureiro's description of Miltus 

 africana suggests a plant with flowers fascicled at the nodes, and I find it dif- 

 ficult to see why it should not be the same as G. pentadecandra E. Mey. 



U MBEL LIFER AE 



Alepidea gracilis 29 Dummer, Trans. Roy. Soc. S. Afr. 3: 11 (1913) var. major Weim.
