vix semipollicares, assurgentes, parum ramosi, interdum flagel- 
liferi. Folia patentia, dissita, florem 9 versus confertiora major- 
aque, ovata ovatove-lanceolata, obtusata, raro retusula, rarissime 
obtuse bidentata; cellule pellucide pachydermes, inferiores 
magne sublineares, superiores duplo fere minores et breviores.

Genus 9. OpontoscHisma, Dum. 
94. O. ProstratuM, Spruce. Sphagnecetes prostrata,. Nees, in 
Syn. Hep. p. 149.—Dominica, Morne Diablotin (665, 680), 
Morne Couronne (233). 
Genus 10. ADELANTHUS, Witt. 
95. A. DEcIPIENS, Mitt. Var., Spruce, in Journ. Bot. 1876, 
p. 196.—Dominica, Morne Diablotin (653, 658, 659, 660). 
Of this species, first gathered in Ireland by Miss Hutchins, but 
only the male plant, Mr. Elliott gathered copious and luxuriant 
but sterile specimens. The fertile plant had been gathered in 
Cuba by Wright, and in the Quitenian Andes by myself in 1857. 
The American form has rather rounder leaves, less sharply toothed 
than the European, but I find no other difference. Mr. Elliott 
did not succeed in finding a second Dominican species— 
A. decurvus, Mitt. (Spruce in ‘ Journ. Bot.’ 1876, p. 199; Hep. 
Amaz. p. 406), of which the Rev. L. Guilding had gathered the 
female plant in that island, and I the male plant in the Peruvian 
Andes in 1855. 
Genus 11. Kantta, Gray. 
96. K. portrortcensts, Steph. in Hedwigia, 1888, p. 280 
(=K. vincentina, H. Wright, in Journ. Bot, 1891, p. 106).—
