MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [Vol. 8, No. 3 



\ 



Mr. Brass* specimen is the first record from Nyasaland. Although Schumann 

 (I.e.) cites Meller's specimen from the Manganja Hills in Nyasaland under D. 

 "mupangae," the specimen is in fact D. rotundifolia (Hochst.) Planch. 



Waltheria indica L. Sp. PI. 673. 1753. 



Waltheria americana L. Sp. Pi. 673* 1753; K. Schum. in Engl. Monogr. Afr. Pfl.-Fam. 

 & Gatt. 5: 45. 1900. 



Chikwawa District: Lower Mwanza River, one plant on a sandy beach, herb 60 

 cm. high, flowers yellow, 180 m., Oct. 6, 1946, 18010. Widespread in the tropics 

 and subtropics. 



For reasons for adopting W. indica as the valid name instead of W. americana, 

 see Exell and Mendonqa in Carrisso, Consp. Fl. Angol. 1: 193. (1951).

 Tanganyika Territory (fide Burret) and Portuguese East Africa.

Kota-kota District: Chintembwe, rocky grasslands, perennial herb, rootstock 

 large, woody, young shoots flowering after burning of the grass, flowers yellow, 

 1400 m., Sept. 9, 1946, 17586. Southwestern Tanganyika Territory to the Trans- 

 vaal and Angola. 



The treatment of Triumfetta welwitschii and T. mastersii by Sprague & Hutch- 

 inson in their revision of the African Triumfettas (Jour. Linn. Soc. Bot. 39: 231- 

 276. 1909) is unsatisfactory. The varieties of T. welwitschii that they recognize 

 (var. rehmannii, var. laxiflora) are merely stages in development; the changes that 

 the pre-rains flowerers of the African savannahs undergo in a short space of time 

 at the end of the dry season and the early part of the rains must be seen to be 

 appreciated. 



T. mastersii Bak. f., sensu stricto, differs from T. welwitschii only in the 

 slightly shorter and broader leaves; these characters are, however, so inconstant 

 and variable that I feel unable to separate T. mastersii even varietally. 



T. mastersii var. heliocarpa (K. Schum.) Sprague & Hutch, is a very distinct 

 and striking plant in its spreading indumentum and its large, broad leaves with 

 prominent venation and coarsely and densely crenate-serrulate margins, and I 

 would prefer to maintain it as originally published — a distinct species, T. helio- 

 carpa K. Schum.; though I should add that in structure of flower and fruit it does 

 not appear separable from T. welwitschii.
