A note on the relationships of these three plants and their 
immediate allies will shortly appear in the Kew Bulletin. 
M. Treutleri was introduced into cultivation by Messrs. 
Knight and Perry about 1840. It flowered with them in 
1844 and again in 1845, and was figured both in the Botanical 
Register and in Paxton’s Magazine of Botany, in the belief 
that it was MZ. macrophylla, Wall. The area of the species 
extends from Lower Nepal to Sikkim and the Khasia Hills 
at elevations of from 2,000 to 6,000 ft. above sea-level. In 
Sikkim it was collected by Sir Joseph Hooker in 1848, and 
again by Dr. Treutler in 1860, in dense forest below Birch 
Hill, near Darjeeling. 
At Kew M. Treutleri is grown as a stove-plant and 
forms a shrub about 3 ft. high, with numerous branches 
which produce terminal heads of flowers in July and 
August. After flowering the plants are rested dry, and are 
started into growth again in spring by the application of 
heat and moisture. Seeds do not mature, but cuttings of 
the young shoots readily strike roots, 
Descriprtion.—Shrub, branches shortly pubescent upwards. 
Leaves ovate or ovate-elliptic, shortly acuminate, usually 
shortly cuneate at base, 6-12 in. long, 3-6 in. wide, hirsute 
on the nerves on both sides, especially beneath and on midrib, 
elsewhere sparsely harshly hairy ; petioles 3-1} in. long; 
stipules wide-ovate or triangular, acuminate, often 2-fid, 31-3 
in. long, } in. wide, herbaceous. Corymbs many-flowered, 
dense, terminal, often with additional cymes in the upper 
axils; lower bracts broad, sometimes slightly laciniate, upper 
bracts like sepals; pedicels very short. Sepals linear or 
subulate, much and gradually narrowed, herbaceous, almost 
glabrous except the setose-ciliate edges, }-? in. long, 4-3 lin. 
wide, or rather wider; leafy sepal white, otherwise like the 
leaves. Corolla before opening 3-1} in. long, adpressed 
pubescent, when old often almost glabrous; limb orange, in 
bud 5-horned, the horns often rather long; lobes } in. long 
and broad with slender caudate tips; tube with a lining 
of orange hairs in the throat. Berry globose, dry, 4 in. 
across, soon glabrescent. |
