being in the form of the Hp. They are 
chiefly from the moist upland regions 
of New Granada and Ecuador, and their 
cultural requirements are as for Warcze- 
wiczella. The species were mostly de- 
scribed by Reichenbach under Pesca- 
torea though later included, by him 
and by other authors, under Zygopeta- 
lum. Their synonyms are too numerous 
to mention without quotingauthorities ; 
some have even been classed under Bate- 
mannia, where they are quite out of 
place. Species : — 
P. Backhousiana. — Flowers creamy-white 
tipped with purple ; crest yellow. 
P. bella. — Flowers pale blue with the outer 
halves of the segments violet. 
P. cerina. — Flowers creamy-white with a 
yellow lip ; segments sometimes tipped with 
rose. 
P. Daycma. — A variable species generally 
white with green tips to the sepals and a 
purple crest to the lip. Variety candidula is 
pure white, and variety rhodacra white tipped 
with purple and with a rosy-purple lip. 
P. Dormaniana. — Flowers white, with sul- 
phur-yellow tips to the sepals, and a yellow 
crest.

P. Klabochorum. — Flowers white, with 
crimson tips to the sepals and petals, and dark 
maroon hairs studding the lip. 
P. lamellosa. — Flowers creamy-white ; lip 
with a yellow crest. 
P. Lehman?i'L — One of the handsomest 
species. Flowers large, light violet in colour, 
with whitish lines.

Promen^a. — This section comprises 
a small group of dwarf compact-grow- 
ing plants only a few inches in height. 
Promen^a Rollissoni. 
with clustered greyish-green pseudo- 
bulbs and evergreen leaves a few inches 
long. The flowers are comparatively 
large, produced on short stems, and 
grouped closely round theplants. These 
pretty little gems should be grown in 
orchid pans or baskets, and suspended 
in the Cattleya house to bring them 
near the glass, a position in which all 
very dwarf plants thrive best. They are 
evergreen and need no special care be- 
yond a restricted supply of water when 
not in active growth, and there is no
