Cape Province: South-Western Region; Ivlaver, fl. July 1923, 
R. H. Compton (National Botanic Gardens, No. -$f). 
Allied to M. lunatum, Willd., but very distinctly, though finely, 
papillose and with an apple-green tint, very different from the glaucous- 
green of its ally. The leaves are far more turgid and less falcate and the 
whole plant less woody.

oblonga vel rarius supra medium ampliata, apiculata, apiculo interdum 
recurvo, glauca laevissima, ad 2'5 cm. longa, medio ad 0-2 cm. lata, 
0-7 cm. diam., ea in ramulis floriferis saepius 1’5 cm. longa, 0-15 cm. lata, 
0 - 5 cm. diam.; flores 5-meri, rite bi-ternati, ad P2 cm. diam., meridie 
expansi, pedunculis, praeter ultimum, medio 2-bracteatis, in calycem 
haud gradatim transeuntibus ; calycis tubus subcrateriformis, basi sub- 
truncatus, medio leviter constrictus, 0-2 cm. longus, segmentis ovatis 
acutis, inter se aequilongis, 0-3 cm. longis, tribus membranaceo-margina- 
tis; petala inter se subaequilonga, spathulata, acuta vel rarius obtusa, 
rosea, marginibus saturatioribus, 0-4 cm. longa, 0-1 cm. lata; stamina 
conico-collecta, staminodiis longe barbatis, inter se intertextis, circum 
data, filamentis pallidis, medio vel apice barbatis, ad 0-2 cm. longis, 
antheris luteis; discus conspicuus annularis, irregularity partitus; 
ovarium supra planum, sive in medio vero elevatum, stigmatibus lineari-
