compares to those of the rusty-leaved vatiety of Magnolia gran- 
diflora, but the green is of a much deeper hue. It inhabits the 
summit of Tonglo Mountain, Eastern or Sikkim-Himalaya, at 
an elevation of 10,000 feet above the level of the sea; and, as 
may be expected, we have found it stand the winter in the open 
air; but in a climate subject to dry, piercing, east winds at the 
flowering season, it is in vain to expect blossoms; and even the 
young branching shoots are liable to be killed, unless some kind 
of protection be afforded at the season of blossoming. Mr. Booth 
sent the same species to Mr. Nuttall, from Bootan, and he has 
called it R. venosum. 
Descr. Our plants have at present only attained a height of 
three to four feet; but on their native mountains they are trees 
thirty feet in height, with trunks often two feet in diameter, and 
branching from the base. Young branches thick and downy, 
bearing the spreading foliage at the extremity, and glutinous, 
woolly leaf-buds enveloped in imbricated scales. The young leaves 
are all over woolly with ferruginous down : the fully formed ones 
are eight to ten inches, and even a foot in length, coriaceous, 
thick, elliptical or obovate, obtuse at the base and at the apex, 
but with the latter submucronate; the upper surface naked, 
dark, glossy green, penninerved, and reticulatedly veined (the 
veins sunk), beneath prominently veined and densely clothed 
with more or less bright rusty-coloured down, the down often 
deciduous on the veins. Petioles not more than an inch long, 
but very thick and slightly transversely wrinkled, glabrous. 
Flowers collected into a large head, numerous, white, and with 
a dark purple or chocolate-coloured spot at the superior base 
within, conspicuous also externally. Calyx obsolete, of five 
minute lobes, quite concealed by the base of the corolla. Co- 
rolla campanulate, large (three or four times as large as those 
in the figure above quoted, but like them in other respects), 
eight- or ten-lobed at the moderately spreading limb; -lobes 
rounded, obtuse. Stamens twelve or sixteen, shorter than the 
corolla, declined: filaments subulate, woolly below: anthers 
small, brown. Ovary pyramidal, very woolly and glutinous, 
sixteen-celled, with as many small glands on the outside at. 
the base: sfyle geniculated above the middle, thence thickened 
upwards. Stigma very large, nearly orbicular, umbilicated. Cap- 
sule elliptical, cylindrical, downy.
