MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [Vol. 9, No. 1 



centae, confirms the suspicion, which I have held for long, that the species is a 

 Dicliptera. I am indebted to my friend, J. E. Dandy, for calling my attention to 

 Hope Simpson's gathering. Since I wrote the above, an excellent gathering in fruit 

 has been made by A. A. Bullock. 



Dicliptera sp. 



North Nyasa District: Nyika Plateau, abundant in juniper forest undergrowth, 

 herb about 1 m. high, flowers rose-purple, 2250 m., Aug. 11, 1946, 17161. 



This plant is placed in Dicliptera by inference in the absence of ripe cap- 

 sules. It appears similar to D. lingulata C. B. Clarke in its habit, but differs from 

 that species in the shape of the bracts and bracteoles. Incidentally D. lingulata 

 is also from the Nyika Plateau, where it was collected by Alexander Whyte in 

 1896 and has never been recollected. 



Dicliptera sp. 



Cholo District: Cholo Mountain, occasional in rain-forest undergrowth, flowers 

 pale pink blotched with dark pink, 1350 m., Sept. 26, 1946, 17817. 



This plant does not match any of the named or unnamed specimens of Dicliptera 

 at Kew. As the available material is not particularly good, with only two flowers 

 and without fruits, I prefer to leave it without a name until it is possible to revise 

 the genus. 



Peristrophe bicalyculata (Retz.) Nees in Wall. PI. As. Rar. 3: 113. 1832. 



Dianthera bicalyculata Retz. Sv. Vet.-Akad. Handl. 36: 297. 1775. 



Kota-kota District: Chia area, on grassy flood-banks of woodland streams, 

 shrub 1 m. high, several weak almost leafless stems produced from a common 

 rootstock, flowers pink marked with purple, fragrant, 480 m., Sept. 3, 1946, 17508. 

 Widely spread through tropical Africa and Asia; new to Nyasaland. 



SEL AGIN ACE AE 



Hebenstretia dentata L. Sp. PI. 629. 1753; Rolfe in Thiselton-Dyer, Fl. Trop. 

 Afr. 5: 265. 1900. 



Mlanje District: Mlanje Mountain; Chambe Plateau, occasional in grassland, 

 shrub 30-100 cm. high, corolla cream with an orange-red spot at base of lower 

 lobe, 2000 m., July 9, 1946, 16761; Luchenya Plateau, common very locally among 

 rocks in grasslands, shrub about 1 m. high, flowers white with an orange blotch 

 on upper lip, 2200 m., July 11, 1946, 16788. Kota-kota District: Nchisi Mountain, 

 common among rocks in Brachystegia woodland, shrub 60-80 cm. high, flowers 

 white with orange patch on lip, 1600 m., July 26, 1946, 16963. North Nyasa Dis- 

 trict: Nyika Plateau, plentiful on shrubby edges of forest, shrub 80-100 cm. high, 

 stems one or several, erect from a thick stock, flowers white with orange patch 

 at base of lip, 2340 m., Aug. 12, 1946, 17187. Widespread in eastern tropical 

 Africa from the Anglo-Egyptian Sudan southwards to Angola and South Africa. 



Selago L. Rolfe's account of Selago in the Flora of tropical Africa is un- 

 satisfactory, to put it mildly,, and an honest attempt to use his key is liable to 

 lead to nothing but bewilderment and exasperation. The reckless creation there 

 of new species is really almost worthy of Gandoger. I found it impossible to use 

 this uninspired work in naming the specimens collected by Mr. Brass, and that 

 the only thing to do was to revise altogether the tropical African species; the 

 following account is an endeavour to replace chaos by order. 



In the Flora of tropical Africa Rolfe made a primary division of Selago on 

 whether the calyx is 5-lobed or only 2-3-lobed. In the Flora capensis Rolfe sep- 

 arated the latter group from Selago as a distinct genus Walafrida E. Mey. There is
