mittee, and have drawn up a constitution with a view to keeping 

 themselves up to the mark and providing i7iter alia that they 

 should meet periodically to compare notes, and that no names 

 should be handed to the police for prosecution until the cases 

 had been submitted to the committee or a sub-committee 

 appointed to supervise prosecutions. The reason for this latter 

 provision is, of course, to avoid the possibihty of the movement 

 being injured by hasty or mistaken prosecutions." 



SHORT NOTES. 



EosA siNiCA. — Rosa sinica is often cited as of Ait. Hort. Kew. 

 (ed. 2, iii. 261) — e.g. by Lindley, Rosarum Monographia (1820), 

 Hemsley in Index Fl. Sinensis, i. 250, Hook. f. in Fl. Bl-it. Ind. ii. 

 364 — to designate a species distinct from R. sinica L. Syst. Veg. ed. 

 13, 394 (1774), a plant with subglobose glabrous receptacle. 

 Alton in his first edition (Hort. Kew. ii. 203 (1789) ) merely 

 copies Linngeus's diagnosis ; the reference in the second edition 

 is a repetition of the first. R. sinica Ait. is therefore identical 

 with R. sinica L. Alton adds " cult. 1759 by Mr. Philip Miller." 

 Miller makes no reference to this species in his Dictionary, and 

 there is no specimen from him in the Banksian Herbarium. 

 Eobert Brown in his MSS. writes: "said to be cultivated in 1759 

 by Mr. Philip Miller, and as there is no reference to his Dictionary, 

 it must be inserted from the memory of Mr. Alton, the elder." 

 R. sinica as a synonym or closely allied species of R. lavigata 

 starts with Lindley, whose description is based on a specimen 

 from Bladh in Herb. Bank, whose figure is copied from a Chinese 

 drawing in the same collection. R. sinica L. is probably the 

 same as R. inclica L., see Lindley, op. cit. — W. Fawcett. 



Lecanora isidioides Nyl. in the New Forest. — This 

 extremely rare and local lichen, which has hitherto been recorded 

 in Great Britain from a small area in North Wales only, was 

 found quite recently (April, 1914), growing in a part of the New 

 Forest, near the hamlet of Cadnam. It is on the mossy trunk of 

 an oak tree, southern aspect, and extends in more or less isolated 

 patches from one to eight feet above the ground. The plant is in 

 a very healthy and vigorous condition, both in the development 

 of the thallus and in the production of apothecia. Crombie says 

 [Monograph of Lichens foimd in Great Britain, parti., 1894): — 

 " The thallus is rather scattered, greenish grey when moistened, 

 usually but sparingly fertile, though in one corticolous fragment 

 the apothecia are somewhat numerous." The New Forest 

 specimens are abundantly fertile, so much so that the apothecia 

 are in some cases slightly angular owing to close contact. The 

 fruits are also, on the average, slightly larger than those of the 

 Salwey and Borrer specimens in the herbarium of the British 

 Museum, but this may possibly be due to the age of the specimens.
