MR. RICHARD SPRUCE’S HEPATIC-E ELLIOTTIAN A. 365 
T can now safely assert that the Peruvian plant and the West- 
Indian are the same species, Mr. Elliott’s specimens gathered in 
two localities in Dominica agreeing perfectly with mine. 
Genus 23. Sympnyoayna, Mont. 
Of the two Symphyogyne gathered by Mr. Elliott, one is new 
and is remarkable for the costa of the frond being traversed by 
three dark ligneous bands or threads. Unfortunately it is 
sterile. 
141. S. srnvuara, Mont. et Nees, in D’Orbign. Voy. p. 61, et

Dioica, in ipsa basi ramosa; frondes 23-8 cm. longas, lineari- 
lanceolatas, undulatas, virentes, margine subrufo repando inte- 
gerrimo, plerumque simplices, raro frondulam anticam emittentes, 
proferens. Costa frondis sat valida, sectione lanceolata, filis 
vittisve tribus—raro superne solum duabus—tenuibus nigres- 
centibus ligneis percursa; limbus unistratus, cellulis magnis 
equilateris constans. lores 9 facie frondis antica orti; ealyptra 
(juvenilis) cylindrica, apice pistillidia plurima gerens, basi ad 
S. brasiliensis instar involucrata.x—Frons 5 mm. lata, cellule 
ji mm. 
Hab. Dominica, ad saxa humida montis Micotrin (Ettrort, 
no. 86, Junio 1892), etiam in monte Trois Pitons (Ex iort, 
no. 774, 887, Nov. 1892), et in Monte Diablotin (Exxiorz,

This plant is a curious instance of a large frondose hepatic 
discovered by G. Forster (on Captain Cook’s second voyage, 
1772-75) in the Australian Islands, having since been found to 
2pd2
