Occasional Notes. 
Cattleya Lawrenceana. n. sp. — The following ex- 
tracts are from the Gardeners' Chronicle. The orchid 
referred to grows not actually on Roraima, but along 
the Kookenaam river, where it flows past the base of the 
southern ends of the twin mountains of Kookenaam and 
Roraima, at an height of about 3700 feet. Reference to 
this same plant has already been made at p. 47 of the 
present number of Timehri. 
The first is a brief article by Professor H. G. Reich- 
ENBACH, f. the great authority on orchids, and is as fol- 
lows : — 
At last we have a Cattleya, bearing Sir Trevor's excellent name. 
Of course it ought to be an extra good plant, and so it is. My know- 
ledge of the novelty is based on the flowers, which have been dried 
with extraordinary skill, even the colours being neatly preserved. 
Then I have before me two plants and several cut bulbs, which illus- 
rate once more the variability of these organs. One before me is a 
little, plump, short thing, m. ci high to 0025, with a short broad leaf, 
scarcely much longer. 0*06 broad. The longest bulb before me is m. 2 
high by o - 025 in diameter. The plants may have been grown ex- 
posed to the sun, as they have a reddish hue on the bulbs and on 
some leaves, the longest of which is 0.22 long by 0^05 wide. The 
trans-se£tion of the bulb is nearly tetragonal, and there are four furrows 
each side. Those bulbs remind one of Cattleya Mossiae. The rhizome 
is of extraordinary strength. The sheath of the flower-stalk is singu- 
larly long, oi61ong by 0015 wide — measured in the withered state. 
Now come the flowers, the grand things. The peduncle is very 
strong, 0*23 long, of purple colour. I have the scars of seven flowers on 
one, and I learn there is evidence of the possession of fourteen flowers, 
which is very promising. The flowers are as large as those of a very 
good Trianae. Sepals uncommonly broad. Petals much broader, 
unusually blunt. There are some flowers with broader petals, and those 
will, no doubt, be received with uncommon favour.
