are the best-known species.

~Eulophia.~--A large genus in which both evergreen and terrestrial plants
are represented. Grow them in the intermediate house.

~Eulophiella.~--The genus includes two species from Madagascar, _E.
Elisabethae_, white, and _E. Peetersiana_, rose. Grow them in a moist
position of the warm house, giving them a liberal supply of rain-water.

~Galeandra.~--These are deciduous epiphytes, needing similar cultivation
to Catasetum.

~Gomeza.~--Allied to Odontoglossum. The flowers are yellowish, and are
produced in racemes. Intermediate-house plants.

~Gongora.~--Intermediate-house Orchids, which should be grown in baskets
or suspending pans to allow of the full production of their long
flower-spikes.

~Grammatophyllum.~--A genus of strong-growing epiphytal Orchids for the
warm house. _G. speciosum_ is a gigantic Malayan species.

~Grobya.~--Brazilian Orchids represented by _G. galeata_ and _G.
Amherstiae_. Intermediate house.

~Habenaria.~--Terrestrial Orchids. _H. militaris_ and _H. rhodocheila_ are
bright scarlet; _H. carnea_, flesh colour; _H. Susannae_, _H. Bonatea_,
and _H. Ugandae_, tall-growing, green and white. The two latter species
will grow in a cool house; the others need greater warmth. The North
American species are nearly hardy, and may be grown in a frame.

~Houlletia.~--Fragrant epiphytal Orchids from South America. Intermediate
house.

~Ionopsis.~--Pretty, slender, white and lilac species. Grow in small
baskets in the intermediate house.

~Laelia.~--One of the largest and showiest genera, great favourites in
gardens, and fine subjects in the hands of the hybridiser. The Mexican
species _L. anceps_, _L. autumnalis_, _L. albida_, &c., used to be
allotted a special dryish intermediate house, but they are now usually
grown in the intermediate or Cattleya house, and rested in a cooler
vinery or corridor. All the species require the same treatment as
Cattleya.

~Liparis.~--A genus of dwarf Orchids chiefly of botanical interest.
Intermediate house.

~Lissochilus.~--Showy terrestrial Orchids, chiefly from South and Tropical
Africa. They should be grown in warm or cool conditions according to
their habitats. _L. Krebsii_ and _L. speciosus_ are two handsome,
cool-house species; _L. giganteus_, _L. Horsfallii_, and others of this
class require a warm house. Being marshy plants, they need weak, liquid
manure when growing.

~Lueddemannia.~--A fine genus of strong, Acineta-like
