ACAULESCENT SPECIES OF MALVASTRUM 227 
12. MaLvasrRUM STUEBELII, Hieron. ti Engl. Bot. Jahrb. xxi. (1895) p. 318. 
PERU : near Cajamarca, Monte Altura de Santa Ursula, Stübel, 38 (Herb. 
Derol.) ! 
This species shows some external resemblance to M. alismatifolium in its 
ovate leaves, but it is quite distinct from this and other species, The large 
flowers are borne on elongated peduncles and the involucral bracts are ovate- 
lanceolate. The laminæ have erenate margins and are covered with hairs on 
the lower, but are glabrous on the upper surface. The calyx is covered with 
а dense felt of strigose hairs, Hieronymus (J. с. p. 318), in comparing this 
plant with М. parnassiefolium, speaks of the leaves as “ supra hirsutis ”; 
they are, however, almost if not quite glabrous above. The affinity suggested 
between this species and the forms allied to М. pornassie folium is probably 
not very close, as the fruits are conspicuously different,

Malvastrum Richi, Baker fil. in Journ. Bot. xxix. (1891) p. 171, partim, 
non А. Gray. 
Peru : Hacienda Атара, near Yauli, Lima-Oroya Ву., 4400 m., Weberbauer, 
360 (Herb. Berol.) ! without precise locality, Maclean (Herb. Kew.) ! 
This species resembles M. rhizanthum in the leaf form and in the size of the 
flowers, but differs especially in the wrinkled and strigosely hairy leaves and 
in the calyces with their ciliate margins. The Kew specimen of M. erenatum 
has been included by Baker fil. J. с. under M. Richii.
