CRITICAL X0TE8 OX SOME HlUTAXXrC .SAXIFRAGES IGl 



in N. Somerset and Cornwall (Dingloss, June 1868, R. V. TeUam in 

 Herb. Brit. Mus. ! ). Ireland, mainly western. 



Formerly I suggested that some'of our rarer " mossy " Saxifrages 

 might be of hybrid origin ; a longer experience, however, makes this 

 seem unlikely. Crossing appears to be common in most gardens ; but 

 as yet my own British species have kept quite unmixed, perhaps for 

 lack of the needful insect- visitors. 



Although it does not, strictly speaking, come within the lines of this 

 paper, I may say here that *S'. stellaris L., Y-dw fontana Druce (pro- 

 visionally) in Annals of Scoftish Natural History, 1892, p. 131, 

 agrees rather well with Engler's description (Mon., p. 132) of forma 

 glahrata Sternb., Suppl. ii. 18 : — •' Tota glaberrima ; stepius folia 

 minora remotiuscula, apice tantum dentata vel Integra. Pedicelli 

 tenuissimi," Engler says that it grows in very moist, spring}^ places, 

 and quotes Fh Danica, t. 23, as depicting it. This figure seems to me 

 to be only the normal plant, with the hairs left out. The specimens in 

 Herb. Druce come from Aonach Mor (96) ; Glen Cailater (92) ; 

 Meall G-orm (105) ; .Ben Wyvis (106), Lady Davy. I think that I 

 have seen it on the Cairngorms and elsewhere. Whether or not it is 

 constant should be proved by culture under more normal conditions. 



SHORT NOTES. 



Double-Flowered Epacrises. Dr. Hemsley contributes the 

 following note to The Garden for March 3 : — " I see with pleasure 

 that a double-llowered Epaci-is is still recommended as a desirable 

 winter-flowering subject. My first knowledge of a double-flowered 

 Epacris dates back to the early sixties of the last century, when the 

 late Baron Ferdinand von Mueller sent to Kew a specimen labelled 

 "■ JEpacris inqjressa var. plenijlora. Stawell, T. Holt." Knowing 

 that Dr. B. Seemann, then editor of the Journal of Botany, was 

 specially interested in double flowers of wild origin, I showed him 

 the specimen, and he recorded it in the Journal of Botany (I860, 

 p. 157) with the remark that it was the first instance of a 

 genuine Australian plant with double flowers. Mueller's specimen 

 is small, but it is densely beset with showy, very double, white 

 flowers. Stawell, I may mention, is in the State of Victoria. 

 Dr. M. T. Masters examined the specimen in question and gave the 

 result in the same volume (p. 35-1). It exhibits the hose-in-hose 

 form of doubling, the corollas being repeated one within the other, 

 the lobes of each alternating with those of the one immediately pre- 

 ceding it. Mueller himself records two double -flowered varieties of 

 Epacris, namely, E. impressa \w.r. plenijlora, from Nunawading and 

 Port Phillip, where it was rare; E. purpurascens m-ax. pleniflora, on 

 rocks at Parramatta, near vSydne}^ New South Wales. The Kev. W 

 WooUs, writing in 1885 on the double flowers of Australia, states that 

 no family of the Australian flora has such a tendency to produce 

 double flowers as the Epacridacece. E. purpurascens was one of the
