SPECIES OF MESEiMnKYANTHEMUM. 



101 



tlie late Prof. Pearson in 1911, The plant has not flowered at Ke\\% nor 

 with myself during the period it has been in cultivation. 



It is allied to M, calculas^ Berger, but is truncate instead of rounded at 

 the top, the orifi(3e is more depressed, with much more conspicuous dimples 

 at the ends of it, and the colour is a rather whiter green. In appearance it 

 is a very distinct species.

at tbe basal part, and bearing a pair of bracts at or above the middle. 

 Bracts large, overtopping the flower^ leaf-Hke. Calyx unequally 4-lobed ; 

 lobes leaf-like, terete or slightly subulate, very obtuse, two pairs of them 

 nearly three times as small as the others^ with membranous margins at the 

 lower part. Petals numerous, imbricate, the longer about equalling the 

 larger calyx-lobes in length, entire, obtuse, dark reddish (saturatissime 

 rubicundis), shining. Stamens numerous, shorter than the petals; filaments 

 rosy ; anthers fuscous ; pollen wdiite. Stigmas 10-12, short, small, at length 

 spreading, plumose, parabolically acuminate, whitish-green.— AT. ci/lmdricifmy

South Africa. Locality unknown. Introduced by Masson about the 



year 1792. 



This distinct-looking species appears to have disappeared from cultivation. 

 Haworth states that the leaves are ''more glaucous, longer, more regular 

 and more upright and cylindrical than those of il/, corniculatum'^ (not the 

 M. corniciflattnn of Linn.^us, but the plant Haworth at first mistook for that
