sight, but multifid almost to the base; and the segments are 
often again divided. It would appear, from the numerous collec¬ 
tors through whom I have received it, to be common in many 
parts of Mexico and Columbia. Ouf living plants were raised 
from tubers sent by Mr. Purdie from open grassy mountains of 
the Nivada de Sta. Martha, New Grenada; they flowered both at 
Sion and the Roval Gardens in October, 1845. The flowers 
are solitary, small, and of a deep rose colour.— Bot. Mag.

CACTACEiE. — Icosandria Monogynia . 
Cereus grandiflorus Maynardi (Garden Hybrid). This beautiful 
hybrid was raised in 1837 by Mr. Henry Kenny, gardener to 
Viscount Maynard, at Easton Lodge, Dunmow, Essex. A flower 
of C. speciosisswnus was fertilized with the pollen of C. grand? - 
Jiorus. The habit is trailing like the latter, and like that species, 
its flowers always open in the evening; but they continue ex¬ 
panded about three days, and are in size from nine to eleven 
inches in diameter, and from seven to nine inches in length, from 
the base of the tube to the expansion of the sepals. It flowers 
equally as free as C. speciosissimus , and though it has not the 
rich violet tinge of that species, possesses a still more vivid 
colour in the scarlet portion of the flower. The wood and spines 
are intermediate between the two species, and very distinct from 
any kind previously raised.— Pax. Mag. Bot. 
Orchidace^:. — Gynandria Monandria. 
Brassia brachiata (Lindley). This beautiful plant was originally 
defined from a dried specimen collected near the Hacienda de la 
Laguna, in Guatemala, by Mr. Hartweg. Since its introduction 
it has occasionally flowered, as with Messrs. Rollisons and with 
Mr. Bateman, but it remains a comparatively scarce species. It 
is far handsomer than either B. guttata (alias Wrayce ) or verru¬ 
cosa, , and its flowers many times larger. The only species that 
really can vie with it in beauty is B. macrostachya. — Bot. Reg.

Bendrobium Veitchianum (Lindley). We are not sure that 
this will not prove a rival to the best of the East Indian Orchids. 
It is a most beautiful plant, with upright racemes of large mossy
