324 Harry Bolus: Plantae africanae novae. V. 



se perinaequalibus 0,6—1.3 cm longis; petala sub-4-seriata basi cum 



staminibus in tubum coalita erecto-patentia recurvata anguste linearia 



acuta vel acuminata dilute straminea 1—1,7 cm longa vix 0,1 cm lata; 



stamina petalis breviora inclusa; ovarium supra planiusculum, stylis 5 



erectis conniventibus filiformibus 0,4 cm longis. — Cape Colony: Mat- 



jesfontein, fl. July, N. S. Pillans, 969! (in herb. Bolus); Calvinia Div., 



Onder-Bokkeveld, near Papelfontein, approx. alt. 660 metres, Aug.! 



Schlechter, 10913! (in herb. Bolus, etc.); ClanwiUiam, Leipoldt, 665, 



(in herb. Albany Museum). — Mr. N. S. Pillans informs me that the 



leaves of this very interesting species are deciduous in the summer, and 



that the plant finally dies down, leaving no trace of its existence above 



the ground until about May or June, when it sends up new shoots all 



round the root-stock. — It is quite unlike any other species hitherto 



described in the genus. The leaves are very crowded — a short stem 



bearing as many as 22 — and spread limply, giving the plant a densely 



tufted appearance. The papillae on the leaves are very minute; some 



are green and some glittering. The latter, being arranged somewhat in 



a honeycomb manner, give the leaves a curiously mottled appearance. 



— The flowers, except in the colour of the petals, are very much like 



those of M . viridiflorum, as figured by Salm Dyck, § 54, fig- 5. — The 



descriptions of the foregoing species of Mesembrianthemum were all (with 



the exception of that of M. intrusum, living material of which was kindly 



supplied by Dr. Marloth) made from living plants which flowered in Mr. 



N. S. Pillan's garden, Rosebank, near Cape Town — without whose 



generous aid they could not have been done.
