rey. Mr. T. Twining, jun,, exhibited a large collection of cultivated specimens from 

 Twickenham. Mr. M. J. F. Sidney presented a specimen oi Lycopodium lepidophyl- 

 lum from Valparaiso. Mr. Adam Gerard presented a collection of plants from Sierra 

 Leone. Dr. J. B. Wood presented specimens of Carex elongata, collected at Chorl- 

 ton, near Manchester, (Phytol. 198). Donations to the library were announced from 

 the Natural-History Society of Northumberland and Mr. M. J. F. Sidney : and Bri- 

 tish plants had been received from Mr. Sidney. Read, the continuation of Mr. Edwin 

 Lees' paper (commenced at the last meeting), — " On the Flora of the Malvern Hills. 

 Part 3 : being a Sketch of the Cryptogamic Vegetation indigenous to the Chain." 



Hepaticce. — Among the Hepaticae occur Anthoceros punctatus and Targionia hypo- 

 phylla, the latter at the foot of the Worcestershire Beacon ; and there are three species 

 of 3Iarchantia, polyniorpha, conica and hemisphcerica. The JungermannicB are not in 

 such variety as might have been expected, though some of them, especially Tainarisci, 

 dilatata and ciliaris, are abundant upon the turf of the hills as well as upon the rocks. 

 Jungermannia pinguis (Linn.) is excessively common, though very rarely fruiting: J. 

 tomentella is a beautiful species that has only occurred in one place, on a dripping 

 rock in " the Gullet.'' The following are all the species Mr. L. had met with : — 

 Jungermannia asplenioides Jungermannia complanata Jungermannia Mackaii 

 ventricosa scalaris serpyllifolia 



bicuspidata viticulosa dilatata 



connivens Trichomanis Tamarisci 



pusilla bidentata pinguis 



resupinata platyphylla epiphylla 



albicans ciliaris furcata 



obtusifolia ? tomentella 



Lichens. — The Mai vera Hills are particularly remarkable for the various lichens 

 they produce, most of which grow in a very luxuriant and beautiful manner ; and in 

 the moist autumnal and wintry months many of the rocks present an appearance from 

 them truly gratifying to the lover of nature. Some of the harder granitic rocks are 

 entirely covered with Umbilicaria pustulata, which at this time is of an olive-green co- 

 lour, and as flabby as a piece of moist leather, though in the summer months it appears 

 as black and sooty as if subjected to the action of fire. On other rocks the deep pur- 

 ple Partnelia omphalodes extends itself, contrasted with wide patches of the grey Par. 

 physodes, the darker P. saxatilis, the dingy P. olivacea, or the conspicuous glaucous 

 pitted thalli of Sticta scrobiculata. On the higher rocks the curled Cetraria glauca 

 grows in abundance ; while a remarkable hoary aspect is imparted to the protruding 

 masses by the silvery Toidium comlloides, and the still more coralline appearance of 

 Spheerophoron compressum. The rein-deer lichen, Cladonia rangiferina, called by Crabbe 



" The iviry moss that whitens all the hill,'' — 



is plentiful on the turf with its allied species, and the sadder and darker Cornicularia ; 

 while in every part the brown and scarlet apothecia of the Scyphophori, in all their 

 multiform varieties, contribute to decorate the scene. Tn the whole, including the 

 cortical lichens, about 220 species are met with. 



It may be specially remarked that the Parmeliaceae and Collematas, and the Pel- 

 tigerous tribe of lichens, are particularly abundant on the Malvern Hills, as well on 

 the moss and turf as on the rocks. Here followed a list of the lichens, most of which 

 accompanied the paper.
