THE ORCHID WORLD. 
[April, 1913. 
Dendrobium Bronckartii. The flowers are 
vermiiion-coloured, with bright yellow hairs 
on the margins of the petals and dorsal sepal, 
the anther-case yellow, and the teeth of the 
column whitish. 
Calanthe violacea, from Madagascar. 
Imported by Messrs. Charlesworth and Co., 
Haywards Heath, and flowered in their estab- 
lishment, January, 191 2. The sepals and 
petals are light purple, and the hp violet- 
purple, becoming brownish as it fades, while 
the crest of the hp is yellowish-brown. 
Epidendrum (Nanodes) congestum, from 
Costa Rica. Flowered m the Royal Botanic 
Gardens, Glasnevin, m January, igil. The 
flowers are pale green, with an emerald-green 
lip, and the column suffused and mottled with 
red-purple.

vaal : high ridge outside Johannesburg.

CATTLEYA BOWRINGIANA. 
THIS Central American species is now 
so well known that any description of 
its botanical details would be uninter- 
esting. When compared with other Cattleya 
species it is of recent discovery, a period of 
less than thirty years covering its whole 
history. 
In its native home it delig-hts in erowing- 
on bare rocks, fully exposed to the sun 
during the day, but at night amply watered 
by the heavy dews. During the growing 
season heavy rains and the vapour arising 
from the many streams running between the 
rocks supply the plants with considerable 
moisture, from which they greatly benefit. 
This humid atmosphere imparts a very succu- 
lent nature to the young growths, which are 
eagerly devoured bv the wild animals of the 
district ; many of the plants are thus broken 
down and rendered worthless for gathering 
by collectors. 
Our illustration shows a grand specimen 
with 180 blooms and 22 newly made bulbs 
flowering m the collection of the Rt. Hon. 
Joseph Chamberlain, Highbury, Birmingham, 
during the late autumn of igi2 The 
immense amount of flower and the free- 
growing nature of the plant clearly proves the 
value of this species to all collections. Not 
only IS this true from a decorative point of 
view, but also from that of the hybridist, 
who during recent years has produced 
many beautiful hybrids by the use of this 
species, both as a seed-bearing and pollen 
parent. 
The early hybrids from this species include 
Cattleya Portia (Bowringiana x labiata), C. 
Mantinii (B. x aurea), C. Mrs. J. W. Whiteley 
(B. X Hardyana), and C. Ariel (B. x Gaskel- 
liana), besides a host of others, all interesting, 
but many having very little distinction of 
specific character to recommend them for 
further hybridisation. 
As may be expected, any hybrid containing 
the elegant and distinct Cattleya aurea in its 
parentage is sure to be used with good results. 
The golden-yellow colour of this species 
invariably brightens up the purple pigment of 
others, a notable example being Cattleya 
Mantinii, m which the rosy purple tint of 
Bowringiana is considerably improved by the 
addition of the aurea colour. Hybridists have 
already taken advantage of this reality by 
using C. Mantinii to a large extent. Evidence 
of this may be seen in Cattleya Freya (Man- 
tinii X aurea), C. Oriel (M. x Hardyana), C. 
Mad. Charlier (M. x labiata), and in Ea?lio- 
Cattleya Messena (M. x L.-C. Cappei), L.-C. 
Milly (M. X L.-C. bletchleyensis), L.-C. Nemea 
(M. X L.-C. Haroldiana), L.-C. Pero (M. x 
Gottoiana), L.-C. Miss Locke (M. x L.-C. Isis). 
L.-C. Miss Gilberta Blount (M. x L.-C. 
Ingramii), and L.-C. Mantmensis (M. x L.-C. 
Behrensiana).
