as the calyx is not glanclulose, but is that mentioned in Baker’s 
monograph as occurring in Leicestershire and Cheshme. In this 
respect Mr. Bloxam’s plant is similar. — J. E. Bagnall. 
E. sijstijla, Bast. Hedge near Shirley, S. Hants, August, 1877. 
— J. Groves. Similar to the Devon systyla, considered by Des%lise 
to be rightly so named. — T. E. A. Briggs. 
Pi. Icucochroa, Desv. Near Eiver Teign, Trusham, 1877. — W. 
Moyle Kogers. A well-marked rose that abounds in Devon and 
Cornwall. — T. E. A. Briggs. 
Pyrns torminalis, Ehrh. Bradfield, Essex, September, 1877. — 
H. E. Fox. A remarkable form with leaves very deeply lobed. 
Saxlfntya hypnoitJes, L., var. Dry limestone rocks. Black 
Head, Co. Clare, Ireland, May 13, 1870. A variety mentioned in 
Cyb. Hib., having the leaves clustered in a singularly dense 
manner, nearly glabrous, the leaves and sepals broader and blunter 
than in hypnoides of the north of Ireland. The tls. small, but 
the stamens larger and rounder. In some quantity on bare diy 
limestone rocks. — S. A. Stewart. 
Tordylktm maximum, L. Ditch-banks, Tilbury, Essex, July, 
1877. — Eyre de Crespigny. This would seem at least established 
in the locality from the further supply sent by the discoverer (see 
B. E. C. Eep., 1876, p. 20). — T. E. A. Briggs. 
Valerianella carinata, Lors. Helston, Cornwall, July, 1877. — 
J. Cunnack. Stone-dyke, Penzance, June 4, 1877. — W. B. Water- 
fall. Several places near Plymouth. — T. E. A. Briggs. Hedge- 
bank, near Bovey Tracey, Devon, May 26, 1877. — W. Moyle 
Eogers. Hedge-bank, Dundonald, Co. Down, Ireland, June 19, 
1877. — S. A. Stewart. Beeston Tor, near Wetton, N. Stafford- 
shire, June 14, 1877. Eiversdale, Derbyshire, June 12, 1877. I 
am convinced that this is as native as V. olitoria, Moench., in the 
limestone dales of Derbyshire and N. Staffordshire. This year I 
found it in two spots in Eavensdale, Derbyshire, growing on the 
limestone crags in company with V. olitoria, amid such purely 
native vegetation as Potentilla verna, &c. Similarly, and again 
mixed with V. olitoria, in the limestone dales near Wetton, N. 
Staffordshire ; and I used to find it in precisely similar situations 
near Buxton in 1868-70. In all these cases the two allied species 
seemed to be inseparable companions. The occurrence of the 
common one was a sure sign that the rarer was somewhere near. 
— Augustin Ley. I quite endorse the Eev. A. Ley’s remarks as to 
this being as much a native as V. olitoria. In the neighbourhood 
of Plymouth it is not restricted to a limestone soil. — T. E. A. 
Briggs. 
V. eriocarpa, Desv. Dry hedge-bank, Eame, E. Cornwall. 
At least established here, June 14, 1877. T. E. A. Briggs. 
East Green, Penzance, W. Cornwall, May 29, 1877. — W. B. 
Waterfall. 
Cardiias tenui/lorus. Curt., form of; C. pycnocephalus, Jacq. 
(verus). On limestone rocks above the coast, Hoe, Plymouth 
June, 17, 1877. On receiving a specimen from me of this peculiar 
form of C. tenuijlorws, kir. H. C. Watson remarked, in a letter :
