November, 1921.] THE ORCHID REVIEW. 
A second type of the same hybrid was also found, a form of great 
interest, verging much more towards O. purpurella, as the first type verged 
towards the other parent. This was a slender dwarf plant, about 1 dm- 
high, with spotted leaves narrower than O. purpurella, very similar as 
regards the general appearance of the lip, but with a very long and stout 
spur, and scented. 
Other types of hybrids were also found, including, in quite large 
numbers, what we should regard as Orchis purpurella X O. latifolia, O. 
purpurella X O. Fuchsii, and O. purpurella X O. ericetorum. 
We are much indebted to Mr. Edward Tattersall for permission to

ORCHIDS OF NEW CALEDONIA AND THE ISLE 
OF PINES. 
71 SYSTEMATIC account of the plants collected by Prof. R. H. 
Jn Compton in New Caledonia and the Isle of Pines during 1914, is 
published in the last issue of the Linnean Society’s Journal (vol. xlv, p. 245). 
The specimens have been presented to the British Museum, where the 
greater part have been determined. The flora of New Caledonia is of 
exceptional interest, especially in regard to the large number of peculiar 
endemic forms. 
Of the 59 species enumerated the following are new: Dendrobium 
Comptonii, with yellow stems, almost covered with the whitish, thinly 
membranous remains of the leaf-sheaths; Bulbophyllum lingulatum; B. 
Comptonii; Phreatia Comptonii, found as an epiphyte on the fallen log in 
moist forest; Phajus neocaledonicus, ovary and pedicel white, lip creamy 
yellow with faint rosy patches outside mouth ; Calanthe oreadum, near the 
endemic species C. Balansae, but differs in floral details, especially the lip 
C. neocaledonica, flowers white, tinged with yellow when old, with a waxy 
appearance, near the last species, but differs in floral details and especially 
in the longer curving-lip ; Sarcochilus neocaledonicus, flowers orange-yellow, 
lip with two fine upwardly directed points ; Acianthus nanus, rather rare in 
moist forest, flowers greenish white tinged with purple; A. culiciferus, 
found among dead leaves, twigs, and humus in forest near river; A. 
bracteatus, flowers dull, dark red; A. corniculatus, plant with much 
anthocyan throughout, flowers smaller than in the last species, and the sub¬ 
tending bract inconspicuous. The two last mentioned species are 
characterized by an appendage about the middle of the anterior face of the 
column, a character which has not, to Dr. Rendle’s knowledge, been 
hitherto noted in the genus. Analytical drawings of nine of the above new 
species are given in plate 13.
