362 MR. RICHARD SPRUCE’S HEPATIC ELLIOTTIAN ¥. 
Syzygiella plagiochiloides var. densifolia except in the compres- 
- sion of the perianth. Possibly the two plants may prove to be 
the same species. As to Nees’s Javan plants, judging from 
specimens in Herb. Hampe preserved in the British Museum, 
one is justified in referring them to the genus Syzygiella, but 
not to S. plagiochiloides, from which S. subintegerrima differs 
widely in habit and in cell-structure. The trigones at the angles 
of the cells do not attain that remarkable development which is 
exhibited in S. plagiochiloides. The perianth is large, turgid, 
longly elliptical, and at the apex plicate and plurifid. The leaves 
(and also the male bracts) are as figured in Lindenberg’s plate, 
but at the postical base are rather widely connate, the margin of 
the connate bases being distinctly reflexed, and beneath them 
tufts of radicles spring from the stem. It is noteworthy that 
the plant originally described as Plagiochila subintegerrima in 
‘Nova Acta,’ xii. (1824), p. 238, is the var. 6 of Nees’s ‘ Enumer- 
atio plant. Crypt. Jave,’ 1830, p. 39, and of succeeding works. 
There is no specimen of D’Orbigny’s plant in the British 
Museum. I see in ‘ Hedwigia, 1893, p. 327, under Syzygiella 
manca, that Herr Stephani considers 8S. plagiochiloides and 
Chiloscyphus mancus to be synonymous.—A. G.]

Genus 19. Juncermannra, Rupp. 
Of the three species, one (J. dominicensis) is new—a minute 
species with round leaves, in size and character near the J. amena 
of Lindenb. & Gottsch., found by Liebmann in Mexico and by
