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



rupestris Engl. Bot. Jahrb, 30: 419 (1901), based on a plant collected by Goetze 

 in SW. Tanganyika, is no doubt another synonym. 



Wahlenbergia caledonica Sond. in Harv. & Sond. Fl. Cap. 3: 579. 1865; Brehm. 

 Bot. Jahrb. 53: 105. 1915. 



Zomba District: Zomba Plateau, on moist grassy slopes, apparently rare, per- 

 ennial herb about 50 cm. high, branches several, ascending from a more or less 

 fleshy sprout, flowers blue, 1450 m., June 5, 1946, 16260. Nyasaland, for which 

 this is the first record, and S. Rhodesia to S, Africa. 



According to von Brehmer's revision of this genus, this would probably come 

 under W. dinteri Brehm. Bot. Jahrb. 53: 106 (1915), which appears to be separated 

 from W. caledonica Sond. only by habit, I do not consider this significant and 

 therefore use the earlier name. 



Brass 16260 is unusual in its characters, even when W. caledonica is taken 

 in a wide sense, particularly in its strong hairiness, its relatively broad, undulate 

 leaves, and its very small corollas. Although these characters can be found in- 

 dividually isolated in W. caledonica, it is possible that their combination may be 

 sufficient to separate the Nyasaland plant, but as Brass 16260 is the only speci- 

 men so far collected, it is still premature to do so.
