had an idea that they did so. The presence of the discoid gemmae 

 supports this view.

 Lake, Dominica, Jan. 1896, 



Obs. The pale green colour, antical margin of leaves spinulose, the 

 small, deeply divided and dentate underleaves, and other characters 

 agree well with Stephanies description.

Obs. Specimens named P. denticulata var. in Spruce's Hep. Am. 

 et And. Exsicc. (K. 1529, Manchester Mus.) agree well with those 

 from Dominica, save that the leaves are rather more acuminate. 



Drepanolejeunea campanuLxVTA Spruce. Small, pale green to 

 brown. Stems 6 to 10 mm. long, pinnate, branches few, long. Leaves 

 distant, patent-divergent (70^) to erecto-patent (30"), twisted, semi- 

 falcate, semi-ovate or lanceolate, acuminate, apex of le.if with a single 

 cell, then 2-2 and 3, margin serrulate, often with a large tooth on the 

 p jstical margin near the lobule, about 10 serrate teeth on the antical, 

 fewer and smaller on the postical margin ; cuticle smooth or slightly 

 papillose; cells small, quadrate or oblong-quadrate, walls thick, no 

 trigones, 2 ocelli on some of the leaves ; lobule 3 to 4 times smaller, 

 tumid, oval or oblong, free angle toothed, keel smooth. Underleaves 

 minute, twice the breadth of the stem, obcuneate, bifid to \ or bi- 

 partite to middle or below, segments divergent, subulate, 2 single 

 cells, then 2-3, disc 3 cells deep by cells wide. Inflorescence 

 dioicous, 9 on short branches, proceeding from stem or branch ; bracts 

 large, oblong acuminate, sen-ate, lobule narrow, oblong, serrate; 

 bi-acteole cuneate, bifid to \, segments acute, serrate. Perianth not 

 seen. Amentula long, 6 to 10 pairs of bmcts, bracts globose, lobule 

 almost equal in size to lobe, keel fringed with large papilla. ; mon- 

 androus.

 Obs. This was named L. inclioata Meissn. by Stephani ; not being 

 satisfied with this determination I was inclined to consider it a new 

 species and as such sent it to Prof. Evans for his opinion. He wrote : 

 " Your new Drepanolejemiea is different from anything I have seen 

 from Puerto Rico and seems to represent a good species. It might be 

 Avell, however, to compare it with Spruce's D. campanulata, with 

 which it has many features in common. Since the closely related 

 jD. infimdihidata grows in the West Indies, D. campanulata is per- 

 haps to be expected there also." Fortunately Dr. Spruce's Herbarium 

 is in the Manchester Museum, so I have had the opportunity of 

 examining all his specimens of this beautiful but very minute and 

 difficult genus. There are two packets labelled D. campanulata, 

 containing, as Prof. Evans says, two species of Drepanolejeunea, but
