MR. J. HOGG ON THE ROSA RUBELLA OF WINCH. 199 



exhibit was one. The second flower I sent to Newcastle ; and 

 very near this bush, I found a second plant with three buds — not 

 expanded — but evidently of the same rose, as the flower-buds were 

 tinted at the ends, and in lines on the back of the folded petals 

 with deep pinh. The bud also exhibited is from this second shrub. 

 I gathered all the flowers and buds, and thus I was unfortunately 

 prevented from ascertaining this autumn the colour of the fruit. 



One of the chief differences between the R. spinosissima and 

 B. rubella, is that the fruit of the former, at first red, becomes 

 when mature black, whilst that of the latter is said to continue 

 red when ripe (see fig. 3. plate 2601, English Botany) ; this last 

 is likewise distinguished by some botanists as being pendulous. 

 Having last week examined the specimens of the H. rubella pre- 

 served in Mr. Winch's herbarium, I must say that the fruit there 

 dried presents neither of these characters, but it is black, or pur- 

 lish -black, and its stalk is straight, and by no means drooping or 

 pendulous. I also noticed that my specimen was less set with 

 glandular bristles on the flower-stalks than that of Mr. Winch's 

 specimens ; but the size and shape of the petals appeared much 

 the same. Eurther, some of the leaflets, as in mine, have simple 

 serratures, while others show a doubly serrated margin ; and in 

 both, the insides of the sepals are downy. 



The flowers in my specimens when fresh were of a lovely pink, 

 and in size are larger than the flowers of the B. spinosissima, with 

 the petals more notched ; but the colours of the flowers of H. spi- 

 nosissima I have never seen other than white, or yellowish-ioJiite. 

 My specimens seem, from the fewer bristles on the flower-stalks, 

 to be rather intermediate between R. spinosissima, whose flower- 

 stalks are smooth, and the R. rubella of Winch's herbarium. Com- 

 pare also the figures m plate 187 sixidi plate 2521 of the 'English 

 Botany.' 



I will leave for the consideration of those who are more familiar 

 with the Rosacea, whether the R. rubella be really a distinct 

 species.
