Singapore. Further material is necessary to clear up these 
points. Several of the Javan species are very imperfectly 
known, and Smith enumerates eight out of thirty-five as 
doubtful. ria is a large and difficult genus, bearing a 
considerable general resemblance to Dendrobium, from which 
it is readily separated by its eight pollinia. The species are 
not commonly cultivated except in botanical gardens, and 
as the fleshy crests of the lip shrink greatly in drying they 
are unusually difficult to discriminate. They are chiefly 
concentrated in the Indo-Malayan region. 
Descriprion.—LEpiphyte, about a foot high. Pseudobulbs 
erect, oblong, somewhat compressed, 24-3 in. long, 
clothed with brown sheaths, 2—3-leaved. Leaves petioled, 
elongate-oblong, subobtuse, coriaceous, 8-12 in. long, about 
13 in. broad, somewhat attenuate at the base. Peduncles 
axillary, erect, stoutish, 4-6 in. long; racemes elongate, 
many-flowered. Bracts ovate, acute, concave, pubescent, 
about 4 in. long. Pedicels about 14 in. long, white- 
tomentose as is the rachis. /Vowers pubescent, white, with 
a yellow anther. Dorsal sepal oblong, obtuse, over 3 in. 
long ; lateral ovate-oblong, obtuse, over 4 in. long; mentum 
oblong, obtuse, about 4 in. long. Petals ovate-oblong, 
obtuse, about } in. long. Lip 3-lobed, about $ in. long ; side- 
lobes erect, triangular, acute; front-lobe reflexed, ovate- 
oblong, obtuse; disk with two prominent fleshy keels, 
channelled. Column clavate, about + in. long.—R. A. Roure. 
_ Cuutivarion—Eria hyacinthoides was presented to Kew 
in 1903 by Mr. F. W. Moore, Keeper of the Royal Botanic 
Gardens, Glasnevin. It is a sturdy grower and produces in 
May several spikes of white flowers which last a long time. 
Like the rest of the genus this species enjoys liberal treat- 
ment during its growing period, which is from April to 
September, and a lower temperature with little or no water 
at_ the root during its resting period. It thrives in a 
mixture of peat fibre and sphagnum in a pan or teak basket 
suspended near the roof glass in the tropical orchid house.—
