Crouch has shown me from Leen Weir, near Pembrid^e ; while the curious fonn 

 of Hypnum Jilicinum, named vaJlis clausce is reported by Mr. Crouch from 

 Lyonshall. Eurhynchixnn specioswn will no doubt be found in some such situation ; 

 I have several times thought I had discovered it, but in vain. 



One more district remains, which no student of Herefordshire botany can 

 aSord to pass over in silence, I mean the limestone of the Greater and Lesser 

 Dowards. Ill as we could spare these hills from the county Flora in respect 

 to the flowering plants (Mr. Burton Watkins has recorded 580-600 species of 

 flowering plants from these two hills alone), I doubt whether we could do 

 without them much more easily among the mosses. The mosses of limestone 

 districts are here found both fine and in abundance. Ditrichum flexicaule and 

 Camptothecium lutescens cover the open parts of the hill, the latter often 

 with fruit ; while on the broken earthy banks of the Little Doward, the 

 limestone Funaria calcarea grows abundantly, along with, and in perfection 

 at the same time as, Hutchinsia petrcea, — nearly the only station for it in 

 our county. A remarkable variety of the common Bryum, ctEspiticium, var. 

 imbricatum, Wils., grows here, and merits further investigation. Encalypta 

 streptocarpa is singularly abundant, but no one has had the luck yet to meet with 

 its fruit. On this plant I wish to remark, in passing, that while it is so abundant 

 and fine on limestone as quite to reckon among the limestone species, on the sand- 

 stone it seems mostly confined to bridges. Wherever flowing water passes beneath, 

 there you are nearly sure to find it clinging in the mortar between the stones. No 

 doubt this is due to the increased coolness caused by evaporation ; but why, if the 

 plant needs this lower temperature on sandstone, does it show itself indifferent to 

 it on limestone banks ? 



The exposed bluffs of the Greater Doward yield several rarities ; Grimmia 

 orbicularis, Trichostomum nitidum, and Hypnum rugosum are all found very 

 near the spot where Mr. Burton Watkins, some years since, detected the 

 Crystal-wort Riccia sorocarpa, before only known in North Italy. In open 

 parts of Lord's wood, Webera nutans and Bryum erythrocarpum are common ; 

 while a single spot, about four yards square, is clothed with a plant nowhere else 

 found in our district, Lcptobryum pyriforine. In the large quarries, Trichostomum 

 crispulum is abundant, and fruited finely this summer ; and this is the only spot 

 where Barbula rtcurvifolia has as yet been found. On the stones, Hypnum Soni- 

 merfelti, and Bhynchosteffium depressum are not rare ; and, on a shady rock, I was 

 fortunate enough to discover the rare Eurhynchium circinatum this spring (1879). 

 The remarkable variety of Hypnum stcllatum, protensum, occupies a level piece of 

 ground overflowed by encrusting springs ; while some precipitous rocks irrigated 

 by these same springs produce Barbula rigidula in abundance. 



It is remarkable, lastly, how many mosses, the fruit of which is rare, 

 are found in that state at the Dowards. One such has been already 

 mentioned, and many more might be added. Barbula tortuosa is not at all 

 rare here with fruit, chiefly in shady situations underneath coppice wood ;
