86 SHORT NOTES. 



me with the following note upon its locality : — " The station for 

 Asarnm Europceiim is about a mile from Halton House, the late resi- 

 dence of Sir John Dashwood King ; it grows all along the hedge in a 

 small copse close to the roadside. Sir John Dashwood King planted 

 a good many flowering shrubs in some of his plantations round Halton, 

 but there are none in the copse where Asarmn grows. It has evidently 

 grown for a long time in its present habitat, and has been known there 

 for several years." This locality has been communicated to me by 

 two other botanists, who have found the plant in this station. It is 

 worthy of note that Halton cannot be many miles distant from the old 

 Hertfordshire locality. I am inclined to think that the evidence is 

 in favour of the nativity of the Amrmn in the Thames province, 

 or at least in the subprovince of West Thames. The Templehouse 

 (Bucks) habitat seems to correspond closely with that at Redlynch, 

 and this is similar to those on the Continent. Dr. Triraen informs 

 me that there is a specimen in Sowerby's herbarium labelled, " Wild 

 near Oxford ; Eev. Dr. Abbot :" so that we have a record of its oc- 

 currence in each of the counties comprised in the West Thames sub- 

 province. As Mr. Watson (Comp. Cyb. Brit.) states that Asarum 

 is " decreasing in Britain," the above Buckinghamshire localities, 

 which have not been before published, may be of interest. — James

Note on the History of the Genus Schrebera, Roxh. — 

 In common with other botanists, I have been delighted to see Dr. 

 Welwitsch's paper on " African Plants " in the twenty-seventh volume 

 of the Linnean Society's Transactions, but I regret to find that, in 

 giving the rather full history of the genus Schrebera, he has overlooked 

 what E. Bureau, Monog. Bignon. p. 100 (Paris, 1864) says respecting 

 the position of the genus, which he correctly refers to Oleacece. And 

 Dr. Welwitsch has further overlooked, that I may fairly lay claim to hav. 

 ing pointed out the true limits and position of the genus, by identify- 

 ing it with Nathusia, not only in my review on Bureau's work (Journ. 

 of Bot. 1864, November 1, p. 357), but also in that part of my ' Flora 

 Vitiensis ' (published October 1, 1866), where I stated (p. 153) under 

 Jasmhiete : — 



" The genus Schrebera, Eoxb., which De Candolle, ' Prodromus,' viii. 

 p. 674, refers to Jasminea (liaving nothing to rely upon except liox- 

 burgh's figure and description), I hold to be identical with Nathusia,
