84 locality on his authority under L, pseudotruncatelle in The 



Gardeners' Chronicle, 1922, vol. LXXI, p. 65, and the localities 

 Jakalswater and Roessinf also mentioned there upon Winter's author- 

 ity, doubtless also belong to a different species, the Roessing 

 plant probably being L. Ruschiorum, N. E, Br. ^ as I learn from 

 Dr. A. Tischer that the true L. pseudotruncatella is only found in 

 the Aus Mountains and near ''*'indhoek.

RIMRIA, N.E. BR. 



Rlmsria microsperma, N.E.Bp. (Fig. 46). — ^temless or nearly 

 so under natural conditions, '^owths solitary or two or perhaps 

 more to a plant. Leaves 1-2 pairs to a growth, closed together 

 or gaping,' united at the base, in adult plants 12-13 lines long, 

 12-15 lines broad and 10 lines thick, half-globose, flat on the 

 face, rounded on the back, obscurely keeled at the apical part and 

 rounded or minutely aniculate at the apex; surface glabrous, very 

 minutely-granulate under a lens, reddish-grey on dove colour, in-

 lines long, compressed, densely "sily-fulvous," Corolla about 1* 

 lines in d'ameter; petals numerous, free, in 2 series, about 8 

 lines lonsa and t-line broad, cuneately linear, obtuse, incvrved

 on the back tinged with rosy-orange at the tips. Stamens about 4 

 lines long, erect in columnar mass, rich golden-yellow; filaments

Great Namaqualand; growing among white quartz stones about 

 12 miles south of "^armbad, Winter. 



I am indebted to Dr. F. Vaupel, the Editor of the iieitschrift 

 f. Sukkulentenkunde , for permission to reproduce from the latter 

 work by means of a photograph sent to me by ^"'^r. C, A. Ivlaass, the 

 accompanying illustration (Fig. 46) of this remarkable specie, v;hlch 

 is evidently closely allied to R. I^ole Svansii, but differs from 

 that species by its dotted leaves and differemtly coliured flowers, 

 it also comes from a locality some hundreds of miles dlstamt* 



In the Zeitschrift f, Sukkulentenkunde, vol.. II , p. 173, Mr. 

 G, Schwantes has created a number of new genera belonging to this 

 group of Plants, and among them, on p. 184, is the genus above 

 Dinteranthus, Schwantes, under which the above plant is placed, 

 together v.'ith Rimaria Pole Syensii, N. E. Br,^ and Argyroderma 

 Margaretae, N. E. Br. That is to say, Dinteranthus is a name founded 

 upon a combination of three species which I have placed under two 

 genera already established, and therefore is entirely inadmissible 

 and only adds unneccessary names to the synonymy. No mention is 

 made of characters by which Dinanthus is distihguishable from Rimaria, 

 and those eiven for Dinteran'hus accord with those of Rimaria. 



f the other genera made by Mr, Schv/antes I have not yet made 

 any study, but judging from the species enumerated under them, 

 some v;ill undoubtedly be acknov/l edged as good genera, and these I 

 note are mostly founded upon species of which (when studying all the 

 available material in the Kew and other ^^erbaria three years ago in
