28 PLANT NOTES, ETC., FOR 1926.
1491. PICRIS SPRENGERIANA Poir. Enc. v., 310. Alien, S. Europe,
Medit. Fowl-run, Bristol, W. Gloster, C. & N. SANDWITH.
1510 (2). HIERACIUM BAUHINII Bess. Alien, Europe. On an Hon
railway bridge, Great Bedwyn, Wilts, C. P. HURST.
1544. H. STENOTUM Dahlst. Modification. Glen Fiagh, Forfar,
G. C. DRUCE. See Zahn 253, n. 19. One of the Oreades under extensum.
Rev. J. Roffey refers it to argenteum-nitidum.
1547. H. BASICRINUM Zahn. (H. SO:&-IMERFELTII, var. TACTUM LINTON).
To this the Rev. J. Roffey refers a plant gathered on the path from the
base of Topley Pike to Chelmerton, near the Churn Hole, Derbyshire,
which Dahlstedt says is nearly allied to his H. plumuligerum. See Zahn
234.
1547. H. SOMMERFELTII Lindeb., var. SPLENDENS F. J. H. Clova,
Forfar. I brought a root from Clova which Linton so named. It seeded
freely, and has spread on to the adjacent walls. Specimens are distributed
this year. It has now received three different names, the Rev.
J. Roffey names DD794 H. T11,bicundiforme Zahn, T1tbiwndum of F. J.
H., not of N. P. See Zahn 204, where it is grouped with the Cerinthoidea,
while Sommerfeltii is put (l.e. 272) among the Oreades. Dahlstedt
thought it was one of the silvatica allied to serrati/rons.
1561. H. LEUCOGRAPTUM Dahlst. Plants which I gathered in Glen
Fiagh, Clova, Forfar, in 1926 were said to be allied to this Rawkweed
by Dahlstedt. Zahn places H. kalsoeense Dahlst. (Le. 188) under which
it comes, in the Cerinthoidea. The Rev. J. Roffey refers the Clova plants
to H. clo'Vense Linton.
1568. R. EXOTERICUM Jord., forma MACRODON Zahn. Abergavenny,
Monmouth. So named by Rev. J. Roffey. Dahlstedt says it is allied to
H. Koehleri Dahlst. See Zahn 315. The Surrey pellucidum of Linton's
set (n. 37) is identified with it by Zahn. Koehleri is put three species
a;way from Jordan's plant in Zahn's Monograph.
1568. R. LUCIDULUM Ley. The Lambridge plant [Oxon DD95]
Dahlstedt says is allied to l1wlanolepis Almq., but differs especially in
its narrower heads, with narrower and more acute phyllaries. Zahn
puts it under pellucidum with which it was at one time identified. Another
plant placed by Roffey under lucidul1Lm from railway-cutting near
Symond's Yat Dahlstedt says is allied to lacerifolium Almq. See Zahn
390, where it is placed among the Euvulgata-caesia = H. triangulare
Zahn. It is quite unlike the Lambridge plant in facies.
1570. H. INTEGRATUM Dahlst. Steeple Aston, Oxford. Plants
" nearly related to this," teste DAHLS,TEDT. See Zahn 321, where it is
placed near variicoZor.
