Plants around Frodsham, Cheshire. 

 —1 think that now for several sea- 

 sons the Liverpool Field Naturalists' 

 Club have honoured Frodsham with 

 a visit ; and for their information, 

 should they purpose to include it 

 again in their arrangements, I give 

 a short list of plants, out of a great 

 number that are generally considered 

 but local in their distribution. On 

 and about Overton Hills may be 

 found Asplenium Adiantum-nigrum, 

 A. marinum, A. Ruta-muraria, Aspidi- 

 um Oreojyteris, Briza minor, Cladium 

 Marisciis, ConvaUariamajalis, Solanum 

 nigrum, Menyanthes trifoliata, Chlora 

 perfoliata, Convolvulus arvensis, An- 

 tirrhinum majus, Osmunda regalis. In 

 the marshes below Frodsham, Utri- 

 cularia vulgaris, Ophioglossum vulga- 

 tum, Ononis arvensis, Hydrocharis Mor- 

 sus-rancB, Aster Tripolium, Vacciniuni 

 Oxycoccos, Armeriamaritima, Plantago 

 maritima, Primula veris, &c. In 

 conclusion permit me to add, should 

 the Liverpool, or any other Field 

 Naturalists' Club, intend paying 

 Frodsham a visit, I shall have great 

 pleasure in acting as their guide, 

 if they would kindly give me a 

 week's notice of their intention. —

Monstrosity of Papaver setigerum, 

 (De 0.) — By Professor Henri van 



Heurck, President of the Societe 

 Phytologique d'Anvers. — M. van 

 Heurck has kindly sent us a paper 

 read by him before the Societe 

 Royale de Botanique de Belgique, 

 of which the following is an abstract. 

 The genus Papaver has already been 

 noticed to have produced a singular 

 monstrosity, by the change of sta- 

 mens into capsules. This pheno- 

 menon has been observed in three 

 species, viz. in P. orientale, by Hugo 

 von Mohl, in P. somniferum, by the 

 elder De Candolle, and in P. duhium, 

 by Elkan. The monstrosity noticed 

 by M. van Heurck differs from the 

 above, and was observed by him in 

 a plant of P. setigeruyn, growing in 

 his garden in 1861. We quote his 

 own description of this singular 

 phenomenon : — '* At the base of the 

 capsule, just above the cicatrice left 

 by the fallen sepal, was a little pro- 

 jection, terminated superiorly by a 

 flower. This projection was not 

 found in several other cases, but the 

 little flowers were placed immediate- 

 ly upon the cicatrice left by the 

 fallen sepal. The little flower when 

 open measured about 9.70 milli- 

 metres [.1063 in.] and the superior 

 sepal 1.5 mill [.059 in.]. The 

 petals were of the usual number, 

 four, but were only rudimentary, 

 and the stamens similar to those of 

 the normal flower ; the latter were 

 formed of a cellular mass, without 

 any trace of pollen, and presenting
