ABDITIONAL NOTES ON MR. W. R. ELLIOTt's HEPATIC^. 83 



Lejexmea atheatostipa Spruce {loc. cit. p. 348) belongg to Dr. 

 Spruce's subgenus Microlejeunea, and was originally " picked out of 

 Wright's Cuban liepatics some years ago." It also occurs very 

 sparsely under Mr. Elliott's No. 212, St. Vincent, in company 

 with two other species of Microlcjeunea and some ten other hepatics 

 and mosses. At one time I despaired of the possibility of isolating 

 the plant ; but, thanks to the kindness of Mr. M. B. Slater, of 

 Malton, the present possessor of the Spruce Herbarium, who lent 

 me the specimen which Dr. Spruce had set aside for himself, and to 

 whom I am greatly indebted for the loan of several other specimens, 

 I was able, after diligent search, to identify the plant and separate 

 a few fertile plants. It is upon these I have based the following 

 description, as I have not seen Wright's Cuban plant. I may add 

 that I have made a drawing, with the help of the camera lucida, 

 and have placed it in the British Museum Herbarium.

Hah. St. Vincent, Eichmond Valley, super Puidulan repens 

 (Elliott, No. 212, Jan. 1892). 



The other species which needs a description is Metzgeria plani- 

 tiscula Spruce [loc. cit. p. 368). The name in the first instance 

 appeared in the Revue Bryoloriique, 1888, pp. 34, 35, and was applied 

 by Dr. Spruce to the plants Glaziou No. 7394 (Brazil) and Balansa 

 No. 4334 (Paraguay), but without any description. Happily there 

 is among Dr. Spruce's MSS. a description of Balansa's plant, 

 which runs as follows : — 



Metzgeria planiuscula Spruce. " M. conjugatae subsimilis, 

 iteratim dichotoma, linearis; costa tenui (diametro 5 cell.) sub- 

 tereti ; limbo latiusculo piano vel subconcavo, solum in sicco 

 margine reflexulo ; radicellis nisi subter costam paucis, marginalibus 

 (ubi rarius adsint) solitariis inaequilongis." 

 Hah. Paraguay (Balansa, No. 4334). 



In Dr. Spruce's paper I took the liberty of adding a note 

 calling attention to certain features in which the three plants 

 differ from one another ; and before I saw the above description 

 I was inclined to refer Glaziou's and Balansa's plants to M. diclio- 

 toma Nees, as emended by Lindberg in his Monoriraphia Metzcferia in 

 Faun. Flor. Fenn. Acta, 1875-7, p. 20, and to regard Mr. Elliott's 

 plant as a possible variety of the same species. Mr. Elliott's 

 plant is fertile, having long pyriform calypti^as (1-5 mm. long x 

 0-75 mm. wide), setulose above. The angle of dichotomy of the 

 fronds is about 75°. It differs from Lindberg's Brazilian specimen 

 in having wider and flatter fronds with margins less widely recurved,
