THE GENUS CHLORAA. 
THE species of Chlorea are handsome terrestrial Orchids, natives of 
‘Chili and the neighbouring parts of temperate South America, but very 
rarely seen in cultivation. It is therefore the more interesting to note that 
three of them are now flowering at Kew. They were collected by 
H. J. Elwes, Esq., during his recent trip to Chili, and have been grown in 
the Bulb pit. The species are C. virescens, C. crispa, and C. multiflora, 
and all of them were described by Lindley from dried specimens. They 
may be compared with Orchis or Disa in habit, but belong to the tribe 
Neottiez, and structurally are nearly allied to Epipactis. 
C. VIRESCENS has already appeared in cultivation, having coeeas in 
‘the Birmingham Botanic Garden, in May 1845, when it was exhibited by 
Mr. Cameron at a meeting of the Horticultural Society. It was figured 
in the Botanical Register for that year (t. 49), when Lindley remarked :— 
«* At length we have the satisfaction of producing a figure of one of those 
beautiful terrestrial Orchids which, under the names of Pichiquen, Gavilu, 
Azuzena, Pico de Loro, &c., are most charming ornaments of the 
subalpine pastures of the Cordillera of Chili.” The species was, however, 
soon afterwards lost sight of. The Kew plant is rather over a foot high, 
and bears.a fine spike of large bright yellow flowers, handsomely veined 
with green. There are also some green tubercles at the base of the petals, 
and a green thickened part at the lip of the lateral sepals. The lip is less 
strongly three-lobed than that shown in Lindley’s figure. 
C. CRISPA is a taller species, and has considerably larger flowers, 
which measure over 24 inches across their broadest diameter. Their colour 
is pure white, with many very minute green dots on the side lobes of the 
lip and base of the petals. The lip is prettily fringed, and bears several 
fringed keels on the disc, while at the base of the column occurs a large 
orange and brown blotch. Two plants are in flower. 
C. MULTIFLORA is about a foot high, and its flowers are less than 
half as large as the preceding. They are cream white, with a large, 
much-thickened green area at the apex of the lateral sepals, a few green 
tubercle-like dots at the base of the petals, and many more on the lip. On 
the latter they occur in five rows along the disc, with a few others on the 
sside lobes. Of this two plants are in flower. 
The species grow under somewhat peculiar conditions, and it is to be 
‘hoped that they will prove amenable to cultivation. Some of these plants 
came from the neighbourhood of Concepcion,but others were obtained at 
the Baths of Chillan, at about 6,000 feet elevation, where the beech forests 
clothe the mountains. Mr. Elwes states that the plants were obtained 
with some difficulty, the long fleshy roots being deeply buried in sand and
