SHORT XOTES 2*2o 



name ERYTHEOCAiiPA : — Oospora late-ellipsoidalis c. 850-400 /a Ion ga, 

 coronula exclusa, 300-850 ^ lata ; evythra, aut rubro-fulva aut rubida. 

 Membrana lineariter-granulata, saepe intervallas leves inter lineas 

 granulatas exhibens. 



The localities from which we have identified the variety are :— - 

 Anglesey, I^lyn Coron (J". E. Griffith); Leitrim, Lough Melvin 

 (i?. Ll.Praeger) ; E. Donegal, L. Magheradrmnman {G. E. B.-W). 



In typical T. nidijica the oospore is much larger than in any 

 form of T. glomerata, and the membrane is wine-red in colour and 

 quite destitute of decoration. — J. Geotes and G. K. Blllock-

Htpeeicum humifusum (p. 195). I possess a long analysis of 

 the soils and habitats of this plant in Lincolnshire, and the}^ practi- 

 cally agree with Mr. H. Stuart Thompson's notes and Bentham's, 

 but methods of ecological research have been carried further. It is 

 truh^ a woodland species, but not of the young thrusting growths, 

 rather of the decaying stage, passing into Calluna moorland. The 

 decay of our Pine- woods between a.d. 800-1400 — i. e., during the 

 vine-growing period for wine — and later of our sandy Beech-woods, 

 has practicalh' ended this species with us generally, for it is only 

 4 to 6 : 1 = very coimnon, 2 = common, 3 = fairly common, 4 = 

 rather rare, 5 = rare, 6 = very rare. It should always be most care- 

 fully noted ecologically when not on mooilands, if it is in the open ; 

 and even on them when with other species as Pyrola minor, Equi- 

 setiim sylvaticum, and E. hyemale, as a proof of woodlands. Dr. F. 

 A. Lees once told me that the plant was specially a bank species in West 

 Yorkshire, I suppose on account of the heavy rainfall. It is not so in 

 this dry county — at least I have not a smgle record in over 600 

 notes. It may be fairly classed as a lime hater, though it is often 

 not so geologically, only ecologically ; for the limey rocks where it 

 is found are acid sandy above, or the upper-root soil is neutral from 

 endless rain-wash and plant-decay in weathering — a sj^ecies of moory 

 humid soils in both cases. Here is a fifty years' soil list for Licoln- 

 shire — all the soils more or less sandy or peaty-decay moory : Lower- 

 Lias-Clay 6 ; Lincolnshire-Limestone 6 ; Corn Brash 6 ; Spilsby- 

 Sandstone 3-5; Chalky-Boulder- Clay 5-6; Sandy-Glacial-Gravel 6 ; 

 Purple-Boulder-Clay 6^ Plateau- Gravel 5-6 ; Old-Piver-li ravel 3-4; 

 Modern -River- Gravel 6 ; Fresh- Water- Alluvium 6 ; Blown-Sand 4-6, 

 rarely 1-2 : quite fifty per cent, of the records are from this soil. 

 Its habitats are : Calluna moors (85 per cent.) 1-4; Commons 2-4; 

 Open-woodlands, rides, paths, scrubs and falls, 2-6 ; Pine woods 1-4 ; 

 Oak-birch 3-4 ; Kough-pasture and golf-links, 5-i5 ; Durmast oak- 

 woods 6. In every known locality the plant occurs in open woods or 

 as a residual of past ones. During the dry series of summers (1893- 

 1910) the plant failed and departed, as did Drosera anglica, Erio- 

 phorum angustifolium, and many other species. — E. A. Woodeuefe-

Having spent a week among the hills north of Liskeard, E. 



Cornwall, and another in theYelverton and Tavistock district of Dart- 

 moor, S. Devon, it may be interesting to add to ray note published in
