BELLIDA iUl 



style-arms already mentioned as asteroideous in nature. Certain 

 HelichryHce, however, have style-arms not markedly dissimilar, and 

 those of the genus Schoenia are virtualh^ identical. It is next to this 

 genus that it would seem fitting to place Bellida. 



The inner florets of B. major are certainly sterile with the style- 

 arms correspondingly reduced (figs. 5 & 6). This is apparently the 

 case with the small florets of B. c/ramiuea also, although their style- 

 arms remain of a fair size (figs. 15 & 16). This character, it should 

 be noted, B&llida shares with Schoenia. 



It may also be mentioned that the difference between the two 

 species in the shape of the achenes — stalked {B. gramineci), rostrate 

 {B. major) — is remarkable in a group where this character may be of 

 generic value ; but the points of resemblance are too numerous to 

 make this a reason for generic separation. As regards further the 

 fruit, besides the elegant sculpturing on the achenes of B. graminea, 

 entirely absent from those of B. major, the almost free pappus-hairs 

 of B. major should be compared with those of the other species, 

 curiously enough, as Ewart has shown, united into two phalanges by 

 two broad basal membranes (figs. 2 & 12). 



It follows from the above that the generic character requires some 

 slight modification and may be stated briefly thus : — 



Bellida Ewart (7. c). Genus Schoenice Steetz proxima abs qua 

 certe distat ob capitula solitaria, antherarum loculos basi rotundatos 

 microscopice tenuissime caudatos, flosculorum sterilium styli ramos 

 breves vel elongatos, achsenia elongata stipitata vel rostra ta. 



A clavis of the species is unnecessary, as the differential points can 

 easily be seen from the figures. It only remains to mention that the 

 prominent rose-coloured pappvis hoisted upon the long achenes gives 

 these plants a very striking appearance.

In this Journal for 1913 (li. 183-199) will be found descriptions 

 of African jjlants, chiefly Khodesian and Congolese, from the herbarium 

 of Archdeacon Rogers of Johannesburg. Further collections from the- 

 same source have since then come to hand containing, as in foimer 

 ones, a considerable percentage of novelties. Descriptions of some of 

 these are hereby appended. It should be mentioned that in most 

 cases the Archdeacon was himself the collector ; where otherwise, the 

 information is gixen in the ordinary way.
