DISTRIBUTION OF THREE SEDGES. 71 



doubtless to distribute the seed. After a high wind, it may some- 

 times be found clinging to fences and trees." 



Poa Dalfouri Parnell. Garbh Bheinn (no. 1649), at 2700 ft.— 

 Var. montana Parnell. Aonacli Beg (no. 1648), at about 3000 ft. 

 Both were named by Prof. Hackel, who adds the following im- 

 portant note : — " 1649 is, however, so near to what in our Alps we 

 call Foa nemnralis var. montana Gaud., that I can find no marked 

 difference. But, again, no. 1648 only differs from no. 1649 by the 

 longer ligula, and by the uppermost node being placed lower down 

 the stem ; so that probably no clear line can be drawn between 

 P. Balfourii and the alpine forms of neworalis. We shall only be 

 able to determine typical specimens with certainty, and shall often 

 meet with specimens which must remain doubtful, or in which it 

 will depend more upon the skill of the observer than upon real 

 positive characters, how we are to designate them." P. alpina L. 

 was only seen on Aonach Beg. 



Aspleiiimi vlride Huds. Aonach Beg. Remarkably rare in this 

 district, considering how largely the mountains consist of mica- 

 schist. 



Addendum. — Since this paper was written, Dr. Focke has identi- 

 fied a bramble collected by the railway near Crianlarich Station, 88, 

 as 7i. Scheutzii Lindeberg, " a form or subspecies of R. rhaninifolius." 

 It differed widely in appearance from all British rhamnifolius that 

 we have met with, when fresh. Cf. the remarks on this plant and 

 Pi. villicaidis by Rev. W. Moyle Rogers, pp. 44-5. 



DISTRIBUTION OF THREE SEDGES. 

 By C. B. Clarke, F.R.S. 



1. Cyperus vegetus Willd. (Sp. PL i. 283) is abundant from 

 Patagonia throughout Argentina and Chili, reaching north as far 

 as Bolivia and Rio Janeiro. It also occurs (perhaps only intro- 

 duced, in my opinion) both in California and Florida, but rarely. 

 C virois Mich, is common in North America, and is the C. vef/etna 

 of Pursh, as N. L. Britton has discovered. The Santee Canal in 

 Florida and the coast of California are particularly rich in ballast 

 plants from various parts of the world ; I do not try to prove JDut 

 that C. vegetus Willd. may be indigenous in Warm Temperate North 

 America, though its home is certainly Warm Temperate South 

 America. 



C. verjetus Willd. is one of the few Chili plants that shows great 

 capacity for colonizing remote lands. It is well established in the 

 Azores. It has appeared in New Zealand under such circumstances 

 that it has been described as a new indigenous species — being 

 C. (jraciUs Buchanan or (J. Buchanani T. Kirk. It was collected 

 near Constantinople by Noe (n. 384), and in Sicily by Tineo. It is 

 well established on the Atlantic coast of Europe from Coimbra up
