PLANTS COLLECTED IN NY AS ALAND 



73 



Transverse sections of the leaf show numerous similar cavities in the meso- 

 phyll, which are presumably to be interpreted in the same way. This suggestion 

 is supported by the fact that similar glands have previously been recorded in the 

 leaves of other species of Clutia. 



All the available material of C. brassii, having been dried for the herbarium, 

 is far from ideal for detailed anatomical work, and the above suggestions are 

 therefore provisional. If anybody refinds C. brassii and is able to collect in spirit 

 leafy stems from living plants, they would be welcomed. 



I must gratefully thank Dr. Metcalfe and Dr. Stant for their help and interest 

 in this matter, and for criticising and adding to the above anatomical notes. 



Clutia abyssinica Jaub. & Spach, Illust. PI. Orient. 5: 77. pi, 468 (1855) var. 

 calvescens Pax, Pflanzenreich 47(4 147(3) ): 57. 1911. 

 Zomba District: Zomba Plateau, one example on a rocky bluff, shrub 1.5 m. 

 high, several stems erect from an enlarged woody stock, flowers greenish, fruit 

 immature, 1500 m., June 2, 1946, 16160; ibid., in rain-forest re growths, shrub 

 2 m. high, sap not milky, flowers greenish, 1500 m., June 5, 1946, 16268, Mlanje 

 District: Mlanje Mountain; west slopes, in brushy growths on a steep rock-slope, 

 shrub 2.5 m. high, of slender upright habit, leaves more or less glaucous beneath, 

 flowers cream-coloured, 1650 m., July 18, 1946, 16876, The variety in eastern 

 Africa from the Anglo-Egyptian Sudan and Abyssinia southwards to Nyasaland 

 and N. Rhodesia. 



Clutia paxii Knauf, Bot. Jahrb. 30: 341. 1901; Pax, Pflanzenreich 47(4 X47(3) ): 60. 

 1911; Hutch, in Thiselton-Dyer, Fl. Trop. Afr. 6 1 : 809. 1912. 

 North Nyasa District: Nyika Plateau, common in forest-edges and second- 

 growths, shrub about 1 m. high, leaves greyish beneath, flowers green, 2440 m., 

 Aug. 11, 1946, 17167; ibid., cT of 27267, 2440 m., Aug. 11, 1946, 17168. Kenya ?, 

 southwest Tanganyika Territory, S. Rhodesia, and now recorded for the first time 

 from Nyasaland. 



Clutia sp. aff. swynnertonii S. Moore, Jour. Linn. Soc. Bot. 40: 197. 1911; Hutch, 

 in Thiselton-Dyer, Fl. Trop. Afr. 6 1 : 811. 1912. 



Zomba District: Zomba Plateau, one example in a moist grassy clearing, shrub 

 1 m. high, flowers greenish, fruit unripe, 1400 m., May 28, 1946, 16066, Kota- 

 kota District: Nchisi Mountain, among rocks in Brachystegia woodland, shrub 

 80 cm. high, flowers and fruit green, 1600 m., July 31, 1946, 27058. 



These two gatherings are very close indeed to C. swynnertonii both in facies 

 and characters, except for the fact that they are monoecious and not dioecious. 

 Whyte s.n, (between Kondowe and Karonga, Nyasaland) in Herb. Kew., is similarly 

 monoecious and is the same as Brass 17058; the Whyte specimen was cited under 

 C. volubilis Hutch, in the Flora of tropical Africa, I am unwilling to name these 

 plants finally, since I feel that the distribution of the sexes may perhaps vary in 

 C. swynnertonii, as it does in some other normally dioecious Euphorbiaceae, e.g. 

 Mercurialis, Further careful observation is required on the spot. 



The monoecious C. kamerunica Pax belongs to the § P auciglandulosae and 

 not, as our plants do, to the § Multiglandulosae; and in addition has a subgla- 

 brous ovary, not pubescent all over, and glabrous not pubescent styles. 



Adenocline acuta (Thunb.) Baill. £tud. Gen. Euph. 457. 1858; Pax, Pflanzenreich 

 63(4 147(7) ): 410. /. 67. 1914; Milne- Redhead, Kew Bull. 1950: 349. 1950. 

 Acalypha acuta Thunb. Fl. Cap. (ed. Schult.) 546. 1823.
