peduncles slightly aciculate. The other collected in October has the 
leaves decidedly doubly serrated, with gland-tipped teeth.” 
Rosa tomentella , Leman, var. affinis , Rau, fide Dr. Christ. Sent 
by Mr. George Nicholson from the banks of the Ure, Ripon, 
Yorkshire, 6th October, 1879. 
Rosa tomentella, Leman, var. Nicholsoni, Christ in litt. Mr. 
Nicholson also sends this variety from the same locality as var. 
affinis , with the following note ' “ Differt a typo aculeis tenuibus, 
aentibus profundioribus, fere simplicifolius ; planta magis glabrata, 
sepala dorso hispidis, fructu ovalis seu rotundato.” This rose 
collected by my brother on the left banks of the Ure near Sharon, 
Yorkshire, has been named as above by Dr. Christ. It has a 
certain fro?idosa look, as that form is understood in Baker’s 
Monograph, but differs from it in its prickles, glandular pedun- 
cles, &c.” 
Rosa canina , L., var. celerata. Mr. Andrew Brotherston sends 
this species from Spylaw, Kelso, Roxburgh, 17th September, 1879, 
from two plants, with the note that there were “several more of the 
same. The plants are much dwarfer and more erect in habit of 
growth than any of the forms of R. sub-cristata , or other canince 
growing along with it.” 
Rosa stylosa , Desv. var. evanida , Christ in litt. Sent by Mr. 
L George Nicholson from Ham Common, Surrey, 8th September, 
1879, with the following remarks: — “ Foliolibus biserratis minoribus, 
poene glabrata, sed pedunculis hispidis et stylo elongato stylosae 
Transitus ad stylosa versus caninam biserratum. Last year I noticed 
a number of bushes of this Rose on Ham Common. It is strongly 
characterized by its numerous flowers, its globose fruits and small 
leaves. Mr. Baker was good enough to examine fresh specimens, 
and as he had not met with the form before J carefully went through 
all the specimens of this section in the TCew Herbarium, without 
finding anything near it. I thereupon sent the plant to Dr. Christ 
of Basle, who pronounced it new and kindly forwarded the above 
name and diagnosis. A somewhat erect bush from 5 to 8 ft. high. 
Prickles on barren stem S/g in. long, and the scar about as deep. 
Leaves of the barren shoot about 4 in. long, with 7 leaflets, the 
terminal one in. long by about in. broad, hairs nearly confined 
to ribs and petiole ; the serration double, teeth acute. Flowers from 
6 to 1 2 or more in a cluster, the peduncles clothed with weak aciculi 
and setae. Calyx tube globose, naked, sepals little more than y 2 in- 
long. Other bushes from the same locality agree thoroughly in all 
respects with that just described, with the exception of their having 
sepals hispid at the back.”
