ROSACEA. 141 



and Cornwall specimens sent to him. The hue of the foliage of systyla 

 is lighter than in most of the plants of the Canince ; the leaves are more 

 sharply pointed ; the peduncles longer, and the calyx -tube narrower. 

 The petals are almost always more or less tinged with pink ; often they 

 are of quite a bright hue ; sometimes they are mottled. The styles 

 usually protrude, but to a very variable extent. The prickles are strong, 

 with very long bases and a short and remarkably uncinate point. Woods 

 clearly understood this plant, and described it well, noticing its elegant 

 habit, cup-shaped flowers, long fruit and peduncle, &c. We have a form 

 with sub-globose fruit. A Rose having considerable resemblance to 

 S7jstyla grows at Gawton, Beer Ferrers (District in.). Except in ha\iiig 

 hairy styles it agrees well with R. virginea, Rip., as sent by the Messrs. 

 Groves to the Bot. Ex. Club in 1876. The name of this latter was con- 

 firmed by Deseglise, in Avhose arrangement of species R. virginea appears 

 near systyla, and immediately before leucochroa.

 It will be seen that I venture to diflfer from my friend Mr. Baker 

 concernmg this rose. I adopt the view of M. Deseglise that it is the 

 R. leucochroa of the Continental botanists, and not the R. collina of 

 Jacquin, with which Mr. Baker would identify it. {Mo7i. Brit. Roses, 

 Jour. Linn. Soc. xi. 232.) It is so common and generally difflised about 

 Plymouth that I have had the opportunity of studying it well, and 

 noticmg its peculiarities. The points of difference between it and our other 

 roses are very apparent to the eye familiar with it. M. Deseglise has 

 had specimens from several places in Devon and Cornwall, and has 

 named them leucochroa. It seems to be nearer to systyla than to any
