MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[Vol! 9, No. 1 



17710; ibid., common in semi-shade in rain-forest, erect herb 0.5-1.5 m. high, 

 simple or sparsely branched, flowers pale pink, 1200 m., Sept. 22, 1946, 17739; 

 ibid., very abundant in rain-forest undergrowth, shrub 1-1.5 m. high, seldom flow- 

 ering at this season, flowers pale pinkish-purple, 1300 m., Sept. 26, 1946, 17819. 

 Nswadzi River, gregarious on shady river-banks, attractive shrub 1.5 m. high, 

 flowers pale purple, 850 m.,. Sept. 27, 1946, 17845. Nyasaland, Portuguese East 

 Africa, and eastern S. Rhodesia. 



With reference to 17710, Mr. Brass mentions that the flowers are dimorphic. 

 This is due to the cleistogamy of certain flowers in the inflorescence, a character 

 which is well known to occur in other species of P seuderanthemum, but which 

 has not hitherto been recorded for P. subviscosum. 



Brachystephanus africanus S. Moore, Trans. Linn. Soc. II. Bot. 4: 31. 1894. 



Mlanje District: Mlanje Mountain; Luchenya Plateau, occasional in under- 

 growth of primary forest, herb about 1 m. high, bracts pink, corolla purple, 1890 

 m., July 12, 1946, 16809. Uganda, Tanganyika, and Nyasaland, and possibly the 

 Belgian Congo. 



B. africanus was based on a plant collected by Alexander Whyte on Mlanje 

 Mountain in 1891, which specimen has until now remained the only record of the 

 species from Nyasaland. Mr. Brass* gathering is therefore of particular interest 

 as it comes from the locus classicus of the species. 



Justicia glabra Koenig ex Roxb. Fl. Ind. 1: 132. 1820. 



Rhaphidospora glabra (Roxb.) Nees in Wall. PI. As. Rar. 3: 115. 1832. 



Chikwawa District: Lower Mwanza River, dry brushy forest, herb about 1 m. 

 high, flowers yellow mottled with purple, 180 m., Oct. 4, 1946, 17944*. Eritrea 

 to Portuguese East Africa and Nyasaland; also in India. 



I follow C. B. Clarke in retaining this species in Justicia, for I consider his 

 definitions of genera to be on the whole more sound than those of Lindau. Al- 

 though sometimes the plant is glabrous, as its name suggests, there are forms 

 with varying amounts of shaggy hairs on the stems, especially near the nodes. 

 Mr. Brass' gathering is particularly hairy, the lower part of the stem being densely 

 clothed with long spreading hairs. 



Justicia nyassana Lindau, Bot. Jahrb. 20: 66. 1894. 



Kota-kota District: Nchisi Mountain, plentiful in rain-forest borders, herb 60- 

 80 cm. high, corolla pink, calyx and bracts reddish, 1500 m., July 28, 1946, 

 16998. Cholo District: Cholo Mountain, very abundant in second-growth rain- 

 forest, herb 50-100 cm. high, habit ascending, flowers white with the lower lip 

 marked with pink, 1200 m., Sept. 21, 1946, 17703. Tanganyika Territory and N. 

 Rhodesia. 



Justicia mollugo C. B. Clarke in Thiselton-Dyer, Fl. Trop. Afr. 5: 200. 1900. 



Zomba District: Zomba Plateau, plentiful in open shady places about habita- 

 tions, herb 8-15 cm. high, flower purple, the lower lip marked with darker purple, 

 1430 m., May 30, 1946, 16088. Kota-kota District: Nchisi Mountain, plentiful in 

 shallow seepage-wet soil in Bfachystegia woodland, herb 10-15 cm. high, flower 

 rose-pink, 1400 m., July 24, 1946, 16913. Nyasaland and N. Rhodesia. 



These two gatherings of /. mollogo confirm Clarke's statement that the spe- 

 cies does not bear abnormal capsules. /. mollugo is an endemic annual which has 

 become a weed in disturbed ground where it enjoys the lack of competition af- 

 forded by man's activities.

 Adbatoda striata Klotzsch in Peters, Reise Mossamb. Bot. 216. 1861.
