WEST INDIAN HEPATICiE 221 



this species by Stephani and Evans, differs from it in its brown 

 colour, ramification, leaves less distinctly dentate or denticulate, 

 absence of the two ocelli, bracts more acute, perianth sub-emersed, 

 broader below, more vase-like, amentula short, 3 to 5 pairs of bracts, 

 not long (6 to 22 pairs, Evans, 20 pairs, Stephani). Spruce knew 

 L. convexistipa, for he refers to it in his notes on O. truncatula S. 

 and gives several localities for it in Hep. Elliottianaj (p. 887). 

 Although near C. convexistipa, I consider it distinct from this 

 species. 



L. surinamensis Mont, is given as a synonym of C. convexistipa 

 by Stephani (Sp. Hep. p. 184), but on p. 187 it is described as a 

 distinct species. The specimens under this name from Cuba, Wright, 

 in the Manchester Museum agree with C. convexistijja. 



C. PERUVIANA (Lehm. & Lindenb.) Evans. Hab. Mountain 

 Lake, Dominica, Jan. 1896. 



Obs. A variable species, although the leaves keep regular in shape, 

 their antical margins vary from being entire to denticulate or 

 spinulose, the underleaves vary in size and from being orbiculate- 

 emarginate on the stems, are often on the branches oval-bifid ; it 

 is a dioicous species and is to be distinguished from other species of 

 the genus by its reddish brown colour and the frequent presence of 

 the "utriculi," kidney-shaped water sacs at the base of some of the 

 branches or on the stem itself ; they appear to be malformed leaves 

 where the lobule has developed abnormally at the expense of the lobe. 



L. Chitonia Tayl. has been referred to C. peruviana by Spruce 

 and Stephani ; but later Stephani reinstated it as a distinct species. 

 Evans considers it a good species and gives {op. cit.) a ful) description 

 and plate. Original specimens in the Manchester Museum confirm 

 Prof. Evans's determination. 



L. adgJutinata Tayl. in Lond. Journ. Bot. v. p. 389 (1846) is also 

 referred to C. peruviana by Stephani; original specimens in the Man- 

 chester Museum ("Cayenne, Herb. Tayl.") appear to me identical 

 with C. Chitonia (Tajd.). These specimens have been seen by 

 Stephani, who wrote on them : " A form of L. peruviana ; what Taylor 

 says about the stipules is not exact ; they are as robust as in most 

 Lejeunecey Spruce, who later saw this note of Stephani, adds : " The 

 stipules of L. peruviana do truly var}^ in size more almost than those 

 of any Lejeunecey The stipules on the specimen in the Museum are 

 large and much dentate. Specimens named O. peruviana in Spruce's 

 Hep. Am. et And. Exsicc. show the different stem and branch under- 

 leaves, as well as the kidney-shaped sacs. 



Under the name C. peruviana are specimens determined by 

 Stephani (Plantse in itinere secundo per Boliviam lectae. Epiph^dl 

 Bergwald von Espirito Santo 1600 m. leg. T. Herzog, Juni 1911). 

 These appear to me to be very different from any form of C. peruviana 

 that I have seen. 



C. ACCEDENS (G.) Evans. Hab. On leaves. Mountain Lake, 

 Dominica, Jan. 1896. 



Obs. Specimens of PrionoJejeunea lepiocardia Spruce in Hep. Am. 

 et And. Exsicc. agree with this species; according to Evans, Spruce
