dentate. This form grows on heathy pasture, with clay and g-ravel 

 underneath. 3. Growing with No. 2, are plants having heads always 

 rayed and phyllary ; appendages scarcely concealing the phyllaries, and 

 with much shorter fringe; tlie leaves very narrow and hardly dentate. 

 The same form grows also on the chalk as at Bowcombe. 4. On the 

 chalk downs grows a plant generally diminutive, but occasionally be- 

 coming tall and branched. A great portion of the phyllaries is not 

 covered by the appendages, the latter being small, with very short 

 fringes, the phyllaries are also much more loosely set. The leaves of 

 this form are usually broader in proportion than those of Nos. 2 and 3. 

 I have sent a few examples of Nos. 2, 3, and 4, but of No. 1 I have 

 not been able to obtain a sufficient number of specimens." — Fred.

Aste7- loiif/ifolms, Lam. In an excursion made to Perth in Septem- 

 ber, in which 1 had the benefit of the guidance of Mr. John Sim, he 

 pointed out to me the Ader which had been sent to Prof. Babington, 

 and pronounced by that botanist to be A. mligmis, Willd. (See 

 Journ. of Botany, Vol. V. p. 369.) The plant grows in great abun- 

 dance over the couple of miles of bank which we traversed, and 

 Mr. Sim assured me that it extended much further down the river- 

 side. As I stated in my last report, A. saUgnns is a doubtful 

 ])lant, but if the Tay-side plant be A. saUgmis, that name is one of 

 the numerous synonyms of the American A. lonc/ifoUus, Lam. Pro- 

 fessor Babington is doul)tless right in considering the Tay-side plant 

 distinct from the Derwent-water Aster, sent to the Club last year 

 by Miss Edmunds. Along with A. long'i/oUus there grow on the 

 banks of the Tay several other species of Astei' in small quantity, 

 among which are A. pimiceus, L., A. 'prenanthoides, Muhl., and a 

 broad-leaved species which I believe to be A. Novi-Belgii, L., but 

 which Mr. H. C. Watson inclines to call an abnormal growth of A. 

 brnmalis, Willd., a plant which according to Torrey and Gray is not 

 certainly known to exist in North America, and is perhaps derived from 

 A. Novi-Belgii. 



Ergtlireea pulcheUa, Pries. " This condensed form grows in the 

 salt marshy ground near King's Quay, Isle of Wight, the plants this 

 year occupying a considerable space of ground, and standing up ratlicr 

 thickly together, with no other form of Erijlhrrea intermixed with them, 

 though both E. Cenlaur'mm and the ordinary form of E. pidvhclla grow 

 in similar ground adjoining."- — Fred. Stratton. ]\Ir. Strattou's speci- 

 mens of E. piilchella are much more condensed than in the normal 

 form, but very much less so than those collected by Mr. H. C. Watson 

 in Guernsey. 



Riimex conspersMS, Ilartm. (?) In August and September I collected 

 specimens of a liiancx identical with tiie plant found by the late Dr. 

 Walker-.'Vrnott, in Kiuross-shire, which, when the ninth volume of 

 ' English Botany ' was published, was thought, both by Mr. H. C,
