364 MR. RICHARD SPRUCE’S HEPATIC ELLIOTTIANS. 
Genus 20. AnrcuLarta, Corda? 
To Alicularia (= Nardia, Gray & Lindberg ex parte) I now 
refer, but doubtfully, the curious Jungermannia succulenta, Rich., 
of which Mr. Elliott gathered numerous specimens, thickly en- 
crusted with the mineral deposits of the Grande Souffri¢re of 
Dominica, where it grew along with Jsotachis serrulata. In 
the Trans. Bot. Soc. Edinb. xv. p. 519, I proposed for it the 
subgeneric name Apotomanthus, from the truncate, obtusely 
trigonous, emersed perianth, in which it is certainly very different 
from the immersed, 5-gonous, microstomous perianth of Alicu- 
laria scalaris, Cord., and its allies. 
136. A. stccuLenta, Spruce. Jungermannia succulenta, Lehm. 
& Lindenb. in Syn. Hep. p. 84.—Dominica, Grande Souffri¢re 
(835, 836, 837, 838, 839, 840, 841, 842, 843, 850, 864, 869). 
Genus 21. Tyrimanruvs, Mitt. 
Of this genus Mr. Elliott gathered all the three species pub- 
lished by Lindenberg, as species of Plagiochila, in the ‘ Species 
Hepaticarum.’ Unfortunately they are all sterile, and there- 
fore do not show the saccate perianth characteristic of the genus. 
137. T. naxus, Spruce, in Trans. Bot. Soc. Edinb. xv. p. 502. 
Plagiochila laxa, Lindenb. in Syn. Hep. p. 35.—St. Vincent, 
Mt. St. Andrew’s (65). Dominica, Morne Diablotin (676). 
138. T. approxtmatus. Plagiochila approximata, Lehm. & Lin- 
denb. in Syn. Hep. p. 49.—Dominica, Morne Diablotin (675). 
139. T. ampnextrotius. Plagiochila amplexifolia, Hampe, in 
Syn. Hep. p. 49.—Dominica, Roseau Valley (73). 
Subtribus v. FOSSOMBRONIE. 
Genus 22. Scatra, Gray (=Haprromrrrivum, Wees). 
140. 8. anprna, Spruce, in Trans. Bot. Soc. Edinb. xv. p. 532 
(=Haplomitrium andinum ejusdem MS. 1856=H. mnioides, 
Gottsche, in Besch. ‘Hépatiques des Antilles Francaises,’ 
1893). (Tab. XXX. figs. 1-6.)—Dominica, Morne Micotrin 
(85), Morne Trois Pitons (767). 
This fine hepatic, a very near ally of our British Jungermannia 
Hooker, Sm., but thrice the size, was gathered by me in the 
Peruvian Andes in July 1856, and named at the time as above.
