342 THE ORCHID REVIEW. 
“Whether they are eventually proved to be species or mere varieties, it 
still remains that there are three forms of Gongora native to Trinidad :— 
tst, the dark purple; 2nd, the spotted ; and 3rd, the straw-coloured ; all of 
which are easy of cultivation at or near sea-level, in positions sheltered 
from the wind.”—J. H. Hart, in Trinidad Bulletin, 1896, p. 222. 
[The vertical arrangement of the rootlets here described is very curious, 
and deserves further investigation. We have several times seen it in 
Catasetum, but could not suggest any reason for the peculiarity, but if it is 
common to other lagoon and swamp plants, it may be a provision for 
enabling the roots to get out-of the water in order to feed on the gases in 
the air. Further observation, however, seems necessary on this point. 
With respect to the species of Gongora mentioned, it is certain that G. 
p and G. quing vis, which are both natives of Trinidad, are 
thoroughly distinct species, and a comparison of the basal horns of the lip 
and adjacent tissue would show some striking structural differences, beside 
the colour. The white variety mentioned is probably the white variety of 
G. nigrita, Lindl., which is well known in British Guiana. There does not 
appear to be any direct evidence of the occurrence of G. nigrita in Trinidad, 
but so many Orchids are common to the two areas that it is highly probable 
it also occurs there. This, too, is a quite distinct species, and the white 
form found in Guiana is simply an albino of it. No doubt the Kew 
authorities could settle these doubtful points if specimens were submitted to 
them.—Ep.] 
NOVELTIES. 
ACANTHOPHIPPIUM EBURNEUM, Kranzl.—A species very closely allied to A- 
Curtisii, Rchb. f., which flowered in the collection of Mr. P. Walter, of 
Magdeburg-Wilhel dt, in July last. The flowers are ivory-white, with a 
yellawieh lip, and orange crest.—Gard. Chron., Sept. 5th, p. 266. 
DENDROBIUM JENNYANUM, Kranzl.—A tall species closely allied to D- 
Mirbelianum, Gaud., which flowered with M. Zollinger-Jenny, of Zurich, in 
August last. It produces long racemes of flowers, which have greenish- 
yellow sepals and petals, and a white lip with some yellow at the base.— 
Gard. Chron., Sept. 19th, p. 329. 
Goncora SANpERIANA, Kranzl.—A Peruvian species closely allied to G- 
portentosa, Rchb. f., from which it is said to differ in various particulars, 
notably in the darker colour of the flower and in some details of the lip. It 
recently flowered with Messrs. F. Sander & Co., St. Albans, who imported 
it.—Gard. Chron., Oct. 17th, p. 456.
