Pseuderanthemum seticalyz, the species now figured, is a 
native of Nyasaland where it was first discovered by Dr. 
(now Sir J.) Kirk fifty years ago. The specific name has 
reference to the attenuate calyx-lobes, not to the presence of 
setae, for the calyx is glabrous or nearly so. For seeds of 
this species Kew is indebted to Mr. J. M. Purves, who 
obtained them on the Fuchila Plateau, Mlangi, British 
Central Africa, at an altitude’ of 6,000 ft., in 1904; the 
resulting plants flowered in March, 1905, 
Marca, 1909.
