NOVITATES AFRICANAE m 
one flower at a time, but when it opens there are usually one or two 
very small flower buds just forming at the base of the peduncle which 
subsequently develop. The open flower lies flat on the ground with 
the calyx buried in the sand.” 
The annulus of the corolla is minutely but densely scaberulous. The 
segments are 0 - 8 cm. long, blotched with reddish brown, and there is 
no trace of ciliation, nor were any hairs to be found in the formalin. 
Disa Begleyi, L. Bolus ( Orchideae-Ophrydeae ). D. bivalvatae, Dur. and 
Schinz, affinis, sed floribus minoribus carneis, sepalo impari valde 
reflexo, haud compresso, petala circuitu suborbicularia, anthera reflexa 
differt. 
Herba glabra gracilis, 7—12 cm. alta; caulis substrictus, per 
totam longitudinem foliatus; folia erecta vel adscendentia, basi 
internodia amplectentia obtegentiaque, lanceolata, longe attenuata, 
2 — 4 cm. longa, suprema lanceolato-ovata acuta; racemi densi sub- 
corymbosi, 2 — 5 cm. diametro, 6 — 12-fl., floribus adscendentibus ; 
bracteae herbaceae, oblongo-ovatae vel ovatae acutae, ovario breviores, 
0'5 — 1'4 cm. longae ; pedicelli ad 0‘6 cm. longi; sepala lateralia patula, 
apice vel parum supra basin recurva, oblique elliptico-oblonga, 0'7 — 
0’9 cm. longa, impari reflexo cucullato, apice rotundato, haud com- 
presso, ecalcarato, 0'7 — 0‘8 cm. longo ; petala resupinata, apice inflexa, 
circuitu suborbicularia, brevissime unguiculata, lamina anteriore ro- 
tundata, posteriore obliqua, 0'5 cm. longa ; labellum patens lineare, 
supra medium paullo ampliatum, acutum, petalis aequilongum ; 
rostelli brachia divergentia, lobo intermedio resupinato ; anthera 
reflexa. 
Cape Province: South-Western Region ; Stellenbosch Div., plateau 
on the Hottentotsholland Mts. south of Sneeuwkop, 4000 — 4500 ft., 
fl. Jan., H. V. Begley (Bolus Herb. No. 13896). 
Closely allied to D. bivalvata, Dur. and Schinz, but differs in having 
smaller pink flowers, the odd sepal strongly reflexed and not laterally 
compressed, the petals being suborbicular in outline, and the anther 
reflexed. 
Acidanthera Muirii, L. Bolus ( Irideae-Ixieae ), ad A. capensem accedit sed 
cormo valde dissimili, foliis paucioribus tenuioribusque, perianthii 
tubo breviore, styli ramis elongatis, spiraliter tortis, distinguitur. 
Glabra, 18— 34 cm. alta; cormus ovoideus obliquus, in collem 
brevem attenuatus, basi planus, tunicis squamiformibus, angustc 
alatis, sature brunneis, ad 1 cm. longus, 0'8 cm. diam. ; caulis gracilis 
herbaceus, 5 — 6-foliatus, apice 1 — 2-florus; folia subflaccida ascend - 
entia plana, anguste linearia, nerviis inconspicuis, infeiioia _ 4, 
5— 16 cm. longa, superiora 2—3, sensim breviora ; spathae valvac
