Lindhergia pseudoleskeoides Dixon. Moorddrift, Waterberg District, 
Transvaal, 1916 ; colL H. A. W. (Nos. 407, 412, 413), c. fr. M. Theriot has, 
moreover, sent me a specimen of this species from Kikuyu, Brit. East 
Africa, collected by the Mission Gromier-Lepetit, July 9, 1911 ; ex Herb. 
Mus. Paris.

P. lesheoides (Schimp.) Broth. Grrahamstown, CP., coll. J. Burton, 
comm. Gr. Webster (Nos. 385, 505, 754) ; rock, Woodbush, Transvaal, 1910 ; 
coll. T. Jenkins, comm. W. Ingham (No. 2). I determine these from the 
description only ; no specimens are to be found in Schimper's Herbarium. 
There are a few old capsules only, on some. 
P. Macowaniana C. M. Macomo's Hoek, 1897 ; coll. Mrs. Clarke 
Williams, comm. C. H. Binstead ; Moorddrift, Waterberg District, Trans- 
vaal, 1916 ; coll. H. A. W. (No. 403). Both c. fr. Mrs. Williams' specimen 
was sent me as P. claviramea C. M., determined, I believe, by Mitten, 
but the leaf arrangement alone precludes that. It differs from the 
previous species in the slightly more robust habit and larger cells, the leaf 
apex almost entire, and the perichaetial bracts longer and more arista te, 
sinuose-denticulate. These are just the characters by which C. Mueller 
distinguishes his P. Macowaniana from P. lesheoides, and I feel no hesitation, 
therefore, in referring the plants there, though with considerable doubt as to 
the value of the specific differences.
