plant at first to be H. diap ha n aides, Lindeb., var. divisum, Jord., 
from which however it differs in having 5 — 6 instead of i — 2 stem 
leaves. — Augustin Ley. 
Hieracium sciaphilum, Uechtr., var. transiens. Ley. Near Ford^ 
E. Glos., v.-c. 33 ; Chalford, v.-c. 33 ; Wotton-under-Edge, v.-c. 34 ; 
Radyr, Glam., v.-c. 41, 1909. Named by Mr. Ley. — H. J. Riddels- 
DELL, 
Hieracium sciaphilum, Uechtr., Mid-^Vest Yorks, v.-c. 64. The 
specimens sent are from various districts. It appears to be well 
distributed both on the limestone and millstone grit formations. 
Hitherto I cannot find that it has been recorded for any locality 
in Yorkshire except Dent Dale. — John Cryer. This packet is 
a mixture ; 6 sheets (Newlay) are H. cacumiuatum, Dahlst. ; 3 sheets 
(Newlay) sciaphilum, Uech., var. transiens. Ley ; 9 sheets (WHiarfe, 
Malham and Clapham) are type sciaphilum, Uech. — A. Ley. 
Hieracium sciaphilum, Uechtr., var. transiens, nov. var. Mid- 
West Yorks, v.-c. 64. Twenty-eight examples, gathered on different 
dates, and on different geological formations in the West Riding 
of Yorkshire. — John Cryer. This also is a mixture : 3 sheets 
(Gordale, Malham, Ribblehead) are type sciaphilum ; 2 sheets 
(Shipley and Ribblehead) are cacuminatum, Dahlst. The 23 which 
remain must not be taken as well representing the var. transiens 
of sciaphilum. Those from Milcar are remarkable for the obtusencss 
of their phyllaries. Place under sciaphilum, sp. coll. — A. Ley. 
Hieracium sparsifolium, Lindeb., var. grandescens, lOahlst. This 
grows in and amongst gorse bushes on a round knoll near Raincliffe 
\Vood, Scarboro’, along with H. vulgatum, Fr., var. subravusculum, 
W. R. Linton. N.-E. Yorks., v.-c. 62, Aug. 4, 1909. — John Cryer. 
This Raincliffe "Wood plant is a remarkable one. In general appear- 
ance it agrees well with var. grandeicens of H. sparsifolium, Lindeb., 
but it has less hair than that plant both on peduncles and phyllaries. 
I understand Rev. E. F. Linton to refer it to ,//. rigidum variety, but 
the large heads as well as their clothing and the general cut of the 
plant point to sparsifolium, Lindeb. It may be a state of grandcscens 
induced by the peculiar situation ; grandescens being usually a plant 
of riverside rocks. — A. Ley. Not a H. sparsifolium variety to my 
mind. I hope to get Dr. Dahlstedt’s opinion on it. — E. F. Linton. 
Hieracium tridentatum, Fr., var. acrifolium, Dahlst. Growing by 
R. Wharfe, near Grassington, Mid-West York, v.-c. 64, .'\ug. 1 1, 1909. 
Record for Yorkshire. — John Cryer. This may be //. tridentatum, 
Fr., var dccipiens. Ley ; but if so it is a state with larger heads and 
broader based upper stem leaves than I ever saw. The specimens
