obtusa, elliptica v. obovata, inferne vix angustata, sape particulis albis excretis obtecta. Flores pauci in ramis brevissimis conferti. Bractea pedunculi numerosa fouis similes sed minores, brunnea, calyce breviores, superiores saltem albo-marginate. Sepala 5 fere libera ovato-lanceolata obtusa vel acutiuscula, albo-marginata, ca. 5 mm. Tonga.

Petala 5 libera ovata obtusissima alba sepalis duplo longiora. Stamina 1 o ad ca. monadelpha, episepala majora, epipetala minora. Ovarium trigono-ovatum, superne angustatum, stigma sessile, stylis nullis. Ovula numerosa omnia placenta basilari affixa. Fructus ignotus.

At first I thought this to be M. prostrata Benth. et Hook. and the more so

because a specimen of Hb. HOOKER f. et THOMSON, named M. germanica Desf var. prostrata, from W. Tibet, 13-15000 feet, agreed with it. Still, another specimen here in the Copenhagen Museum, bearing the same name and from the same herbarium and locality, but from an altitude of but I o 000 —14 000 feet, was very different. This latter is, in my opinion, the true M. prostrata, which by THISELTON DYER in Hook. f., Fl. Brit. Ind. I (25o) (Pl. IV, Fig. 4) is regarded as a var. of M. germanica. It agrees with it in habitus, in having racemes, in the sepals equalling or exceeding the petals and in the stamens being united more than half way up. The present species, on the other hand, is a short-branched dwarf-shrub with flowers single or few together; the sepals are only half as long as the petals, and the stamens are united to the middle only.

To M. Hedinii belongs the first mentioned specimen of hb. Hooker f. et Thomson.
