Tropical Africa. British East Africa: Nairobi, 1800 m., 

 very common on cultivated land, W. J, Doivson 3. 



The only species of Diplotaa^is hitherto recorded from Tropical 

 Africa is D. erucoides, DC, a native of the Mediterranean 

 region and the Orient, which occurs in Abyssinia, according to 

 A. Richard (Tent. Fl. Abyss., vol. i, p. 24), D. inopiiiata bears 

 a superficial resemblance to certain forms of D, erucoides, but 

 exhibits greater afldnity with D. griquensis, Sprague (n. comb.), 

 a native of South Africa (Brassica griquensis^ N". E. Brown in 

 Kew Bull., 1894, p. 353). Both D. inopinata and D, griquensis 

 have siliquas with a short cylindric beak, oblong-ellipsoid seeds 

 arranged in two distinct and regular rows, and truncate cotyle- 

 dons — a combination of characters that, according to Prantl 

 (IN^at. Pflanz., vol. iii. 2, pp. 175-1T6), is characteristic of the 

 genus Diplotams.
