LIST OF ORCHIDEiE. 
(Continued from page 84.) 
182. Huntleya violacea. This plant is destitute of bulbs: its leaves are 
nearly two feet long, and two inches broad ; the flowers are produced on a 
short repent stem from eight to ten inches long, they are of a pale violet blue 
colour. This species requires plenty of pot room in a mixture of turfy 
peat, sphagnum, and a little charcoal; the peat should be in small lumps ; it 
requires plenty of water when in a growing state, with a temperature of 75°. 
— A Native of Demerara. 
183. Huntleya meleagris. This is also destitute of bulbs, and very simi¬ 
lar in growth to the above, only the leaves are rather broader, and the flowers 
are of a darker blue ; the same treatment and temperature will do for this as 
for the other. — A Native of Brazil. 
184. Huntleya sessiliflora. This, too, has no bulbs; its habit is very dif¬ 
ferent to the others, being much dwarfer ; its leaves are not more than ten 
inches long, and two inches broad, ending with an acute point. This genus 
only contains three species at present belonging to that tribe of plants which 
require water all the year round, on account of having no pseudo-bulbs to 
supply them with nourishment, during the time they are at rest; they thrive 
best in a high temperature, and a damp atmosphere. These are rare and 
valuable plants, and should be in every collection. 
185. Hartwegia purpurea. This is another that is destitute of bulbs ; 
its leaves are produced on a short foot-stalk, and are of a dark green, a little 
speckled, the flower spike slender, directed upwards, about 8 inches long, sup¬ 
porting a few rosy purplish flowers ; it is of no great beauty, but may be 
grown on a log of wood, or in a pot with the usual mixture, allowing but 
little water, and a temperature 60° to. 65°. — A native of Mexico. 
186. Houlletia Brocklehurstiana. Plant pseudo-bulbous, bulbs three inches 
long, ovate, deeply furrowed and clothed with large lacerated scales ; its leaves 
are produced singly, of a broad lanceolate form, borne on a long cylindrical 
foot-stalk ; the flower spike usually bears from six to eight flowers, the sepals 
and petals of which are nearly uniform, of a rich fulvous colour spotted all 
over, the outside paler ; the labellum yellow, spotted with purple, sometimes 
the terminal lobe is almost wholly purple. It requires pot cultivation, in a 
mixture of turfy peat, sphagnum, and little lumps of charcoal, and when 
growing should have a liberal supply of water, in addition to frequent 
syringing, temperature 65° to 70°.— A native of Brazil. 
187. Leptotes bicolor. Plant destitute of bulbs, leaves borne on a short 
foot-stalk, and of a rush-like form, four inches long, with a deep furrow 
along the upper side; the flowers are produced in threes and fours, the sepals 
and petals pure white, a little curved outwards round the margin; the 
labellum long and also curved, white, with a large blotch of purple. This 
species should have pot cultivation, in a mixture of sphagnum, turfy peat, 
and rotten wood; it may be grown on a chump of wood, but in such cases 
it will require often watering to keep it moist; the temperature should be 
65° to 70°. — A Native of Brazil. 
188. Leptotes concolor. This species is very similar to the above, but 
hardly so strong growing, the plant itself is of a darker colour : it requires 
the same treatment and temperature. — A Native of Brazil. 
189. Leptotes serrulata. This is a dwarfer growing plant than either of 
the others, with larger flowers of the same form and colour. This genus 
contains but these three species at present; they are all beautiful objects, and 
pot cultivation seems most suitable for them, although, as before stated, they
