oak tree near San Onofro, on the banks of the River Zimapore. In habit it is hardly distinguishable from O. Rossii, 
white sepals banded with brown, instead of green ones ; the lip too is acuminate, not rounded, each stem bears but one 
flower, and the processes at the base of the lip are white, not yellow, and join into an undivided apex instead of a 
o-lobed one. Perhaps as good a way of bringing this species distinctly to the reader's eye is to speak of it as being 
intermediate between O. Rossii and O. stellatum. 
497. MACILERANTHERA TANACETIFOLIA. Nees. (alias Aster tanacetifolius H. B. K.; alias A. 
chrysanthemoides Wil/denow.) A handsome half-hardy suffruticose plant, with large deep-violet 
flower-heads. Belongs to Composites. Native of New Mexico. Introduced at Kew. 
A pretty and singular suffruticose Composite, with flowers nearly as large as a China Aster, and the leaves deeply 
pinnatifid, like some Anthemis, perhaps, rather than Tanacetum. It was seen by Humboldt cultivated in gardens in 
Mexico ; but Dr. Wright appears to have found it wild in Mew Mexico, and from his seeds our plants were raised in 
roeumbent, or rather ascending, half-shrubby plant, with branching slender stems, nearly a foot long, everywhere, as 
well as the foliage, slightly downy. Flower-head large, yellow, with a purple ray, solitary, terminal on the branches. 
Involuere hemispherical, of numerous, spreading, subulate, glandular, herbaceous, scales. Ligules of the ray rather 
garden plant, it produces but a small quantity of perfect seeds, and is not readily propagated by cuttings.—Bot. Mag., 
t. 4634. [Otherwise it would be a fine bedding out plant, its colour being one much wanted in gardens, ] 
498. TRICHOPILIA ALBIDA. Wendland. A stove epiphyte, with white and yellow flowers. 
Belongs to Orchids. Native of the Caraccas. Introduced by M. Otto, of Hamburgh.

pseudobulbs are five inches long, and from six to ten lines broad, flat, somewhat furrowed and sharp- 
cornered, oblong and a little narrow towards the top. The young inflorescence is covered by darkly-spotted sheaths. 
The leaves are a little longer than the bulbs, from an inch to an inch and a half broad, solitary, leathery, somewhat 
heart-shaped and downy at their base, flat, and with reeurved points. The flower-spikes, which generally bear three 
flowers, proceed from the base of the pseudobulb, are from four to six inches long, and of the thickness of a crow-quill, 
The flower is three inches in diameter ; the sepals and petals are alike, an inch and a half long, and three lines broad, 
linear-lanceolate, pointed, waved at the edge, tolerably erect, but inclined a little forwards, not much twisted, pale yellow- 
green, and nearly transparent at the edge. The labellum is smooth, a little longer than the sepals, four-lobed ; the lobes 
are rounded, waved, and crumpled at the edge, and rolled closely together at the base; in the middle of the labellum are 
green towards the base. The hood is three-lobed, the middle lobe being a little prominent, and all fringed. The flowers 
have a faint delicate odour, and last only a few days. This species is closely allied to Trichopilia tortilis Lindl. and 
499. Canna SANGUINEA, Warceewiez, 
Concerning this, which is not the Canna sanguinea of others,

cies, from Costa Rica, was introduced into the gardens of Germany by. M. Warezewiez in 
e open ground in summer ; it flowers freely, and is remarkable for its 
ould be taken up and kept all the winter in à temperate greenhouse. If

uires a warm sheltered place, rich garden mould, and a plentiful supply of water, It seeds abundantly. The 
specimens which we saw in M. Mathieu's garden were three feet high.”
