moreover, is very strongly developed on its under side so as to 

 make it rather more subterranean than in the other species, and 

 no doubt the frequent presence of three spiral elaters is a 

 character of some importance. I have, however, found this 

 feature not infrequently present in Sussex forms of i^. ccBspitiformis, 

 though it is less usual in forms from S. Europe. 



SHORT NOTES. 



Ptilota plumosa Ag. (p. 77). — For over forty years I have 

 been the possessor of a fine and unmistakable specimen of Ptilota 

 plumosa in my herbarium, which was sent me by the late Mr. Henry 

 Goode, as collected by himself " near Falmouth, Cornwall, summer 

 of 1871." I knew Mr. Goode only by correspondence, but was 

 assured of his reliability and absolute sincerity, and as one who 

 only distributed algae of his own collecting, invariably off the 

 coasts of S. Devon and Cornwall. I believe he passed away in 

 the early eighties, at a good old age. His abode was near 

 Plymouth. I may add that I have never myself found P. plumosa 

 Ag. in any Welsh station save that of Path-y-Pistill, Holyhead, 

 where in the summer of 1883 I found many most perfect and 

 beautiful fronds, usually floating. I have searched in vain for it 

 at Penluaen Mawr, Llanfairfechan, Llandudno, Barmouth, &c. — 

 J. Cosmo Melvill. 



Valerianella eriocarpa Desv. — Eeferring to my notes as to 

 the occurrence of this plant in the Isle of Wight ( Journ. Bot. 1912, 

 231 ; 1913, 288), it may be worth recording that on this date 

 (March 2nd) there are thousands of young plants in the same 

 habitat, where in 1912 they were abundant, and where last year I 

 could only find, after long searching, one or two plants. If the 

 Botanical Exchange CIuId or any botanist would care to have 

 specimens I would gladly dry some as soon as the plants are in 

 fruit. — Frederic Stratton. 



Aberdeenshire Plants. — Mimulus mosckatus, reported (Journ, 

 Bot. 1911, 370) as being found by me in Haughton Wood, Afford, 

 Aberdeenshire, is increasing greatly since that date. — Linaria 

 repens still grows at Auchindoir, Aberdeenshire (whence it is 

 recorded in Dickie's Guide (1860) ), where there was once a cottage 

 garden. The stems attain the length of three feet. Cattle had 

 eaten the longest stalks overhanging the dyke, before I (in August 

 last) took careful measure. — William Wilson. 



PoLYPORUs SQUAMOsus. — Somo vory early fruit bodies of 

 Polyporus sqiuunosics have appeared recently in the " Backs " at 

 Cambridge. My attention was called to one of these by Mr. 

 Maltby ; this was a fructification produced inside the hollow 

 trunk of an elm in St. John's College Backs. On further exami- 

 nation of trees, other fructifications were found — several on a 

 horse chestnut near the elm tree, and three or four more on an
