CALLYMENIA LARTERLE 85 



Hab. On brickwork in warm forcing-house, Baldersby Park, 

 Yorkshire, England, Oct. 1904, and Sept. 1905 ; in similar situa- 

 tion in orchid house, Harrogate, Yorkshire, Oct. 1905. Coll. 



G. Webster. 



Differs from S. Bailey i Broth, in the softer leaves, longer, laxer 

 areolation, rostellate lid, &c. ; from S. Wrightii C. M. in the small 

 size, much shorter seta, smaller capsule, narrow-linear teeth, and 

 other points ; from most of the allied species in the longer, looser 

 areolation, as well as in the small capsule with rostellate lid. From 

 all species, so far as hitherto described, in the hyaline pre-peristome. 

 The Glasnevin plant, of which 1 have not seen a fruiting specimen, 

 resembles it in the leaf form and areolation, but the leaf-margin 

 appears to be plane, and if it is identical with S. Wrightii, the 

 fruiting characters would clearly separate it. 



Since writing the above, I learn from Mr. Webster that he has 

 found a few barren stems of the Splachnobryum in one of the orchid 

 houses in the gardens at York in a position where many hundreds 

 of thousands of Cattleyas have been grown during the past twenty- 

 five years, and where no East Indian species have been cultivated 

 in his recollection. As the plant was associated in its other stations 

 with Cattleyas, the presumption appears to be that it has been 

 introduced with orchids of this genus, and that its derivation is 

 therefore in all probability from the tropical regions of the western 

 hemisphere. 



I have to acknowledge gratefully the assistance I have received 

 from Mr. A. Gepp in preparing this description. I may mention 

 that I am sending specimens of the type of S. delicatulum to the 

 herbaria at the British Museum and Kew.

Callymenia renift 



species, of which 



Agardh distinguished three varieties : 



1. Var. cuneata, illustrated in Kiitz. Tab. Phyc. xvii. t. 78, 

 under the name of Euhymenia divisa, and in Zanardini, Icon. Phyc. 

 Med. Adriat. tab. 93, figs. 4-5, under the name of var. Ferrarii. 

 Kiitzing's figure shows a short stalk, rapidly widening out into a 

 frond divided into broad wedge-shaped segments with entire mar- 

 gins, reminding one of a large frond of Dilsea edulis split up by 

 fissures. Zanardini' s figure shows a very short stalk widening out
