THE MUSS/ENDAS OF MADAGASCAR 71 



One of the largest-flowered species known, with corolla-tube 

 nearly 9 cm. long, readily distinguished by the size and long, 

 spreading indumentum of its sessile flowers.

 Distinguished by the dense spreading hairs on the narrow, 



oblanceolate leaves and the branchlets, and by the long linear 

 calyx-lobes, nearly 2-5 cm. long in the flower.

With affinities to M. vestita this is readily distinguished from 

 all the other species by the markedly scabrid upper surface of the 

 leaves. These are elliptical, reaching about 14 cm. x 8'5 cm., 

 with pubescent stalk as much as 2 cm. long ; there are 8-11 

 secondary veins on either side of the midrib; they are but shortly 

 acuminate, with obtuse apex.

Distinguished by the thick, velvety, light-coloured tomentum 

 on the under surface of the leaves. According to Hilsenberg and 

 Bojer the native name is Fatoora.

Species dubi^. 



M. EEiANTHA Rich, in M6m. Soc. Hist. Nat. Par. v. 246 (1829). 

 The description is very inadequate. The indumentum of petioles, 

 branchlets and subulate stipules is described as " rufo-sericeis " ; 

 and the calyx-lobes are lanceolate and equal ; so that the species 

 belongs to the section Landia. The subulate stipules should be 

 distinctive, as also the silky, presumably adpressed, indumentum. 



M. Thouarsiana Baill. Adans. xii. 295 (1879). Based on a 

 plant gathered by Dupetit-Thouars in Madagascar. Described as 

 glabrate, with leaves sometimes irregularly denticulate on the 

 margin ; inflorescence very dense and much branched. These 

 characters are unfavourable to the inclusion of this plant in the
