prefer for the present to place all Mr. Brass' specimens under P. imbricata al- 

 though 16950 has the anticous calyx-lobes slightly spathulate. 



Blepharis (subg. Blepharis § Scorpioideae) sp. 



Kota-kota District: Mpofu, in Brachystegia woodlands, 30-50 cm. high, flowers 

 purple, 960 m., Aug. 1, 1946, Vernay in Brass 17094. 



This specimen agrees well with a plant collected by Buchanan (no. 696) from 

 an unspecified locality in Nyasaland in 1891 and named by C. B. Clarke as 

 Blepharis longifolia Lindau. The type of B. longifolia was from Tanganyika and 

 is not represented at ICew, but a specimen from Tanganyika also named by C. B. 

 Clarke as B. longifolia is specifically different from the Nyasaland plant. Until 

 the much needed revisional work is done, it is best to leave specimens of this 

 section unnamed rather than to give them unreliable epithets. 



Blepharis (subg. Blepharis § Scorpioideae) sp. 



North Nyasa District: Nyika Plateau, common in grassland on edges of juniper 

 forests, herb about 60 cm. high, flowers purplish-blue, 2250 m., Aug. 11, 1946, 

 17179. 



This plant is specifically distinct from Brass 17094, but it is equally difficult 

 to place a satisfactory name upon it.

Cholo District: Cholo Mountain, occasional in rain-forest regrowths, scram- 

 bling herb 2 m. high, flowers pinkish-white, lower lip blotched with violet, 1200 

 m., Sept. 21, 1946, 17709. Widely spread through tropical Asia and Africa. 



Barleria spinulosa Klotzsch in Peters, Reise Mossamb. Bot. 208. 1861. 



Blantyre District: Blantyre, in Brachystegia woodlands, shrub about 1 m. high, 

 enlarged fruiting calyx conspicuously veined with brown, 1100 m., June 17, 1946, 

 16352; ibid., in Brachystegia woodland, shrub about 2 m. high, enlarged fruiting 

 calyx purplish, veined with brown, flower violet, 1100 m., June 18, 1946, 16357. 

 Cholo District: Nswadzi River, in riverine rain-forest undergrowth, shrub 40-50 

 cm. high, fruiting calyx brown, flowers purple, 840 m., Sept. 29 r 1946, 17868. 

 Nyasaland and N. Rhodesia. 



Barleria (§ Prionitis) sp. 



Chikwawa District: Chikwawa, common in dry bushy forest of high river-banks, 

 subshrub to 1 m. high, flowers orange-yellow, 200 m., Oct. 3, 1946, 17920. En- 

 demic in Nyasaland. 



This plant represents what is almost certainly an undescribed species. It 

 agrees well with the two Nyasaland specimens cited under B. eranthemoides R. 

 Br. in the Flora of tropical Africa (5: 147. 1900). It differs from B. eranthemoides 

 in having a two-lipped corolla. Out of the three gatherings I have examined there 

 are only two imperfectly preserved corollas, so that their examination and recon- 

 struction is difficult. It seems, however, that there is a marked bend at the apex 

 of the corolla-tube, a character which is unusual in Barleria. The description of 

 this species should await further gatherings in the flowering state, so that the 

 presence of this character may be confirmed.
