26 R. A. PEYOR NOTES ON A PROPOSED 



uncommon in the St. Albans district. The form with the leaflets 

 cut into linear segments occurs in the eastern division of the county, 

 as also in Bedfordshire. It was distinguished by Morison and 

 Sherard, but until recently had dropped out of notice. The nan-ow- 

 leaved form of Heradeum also has been observed in several places 

 about Harefield. This is, however, no permanent variety, and 

 has even been seen growing from the same root as the usual 

 form. 



Shcm latifolmm. — In several parts of the Harefield Eiver. Elack- 

 stone, the sole authority, 1746. 



(Enanthe crocata. — An immature specimen gathered by the Eev. 

 R. H. Webb near Rickmansworth is the only representative in 

 the county of this poisonous umbellifer, which is so conspicuous 

 in many places by the Thames. It appears, however, to be rightly 

 named, and deserves some further investigation. 



Valerianella auricula. — Otterspool (Alchome MS.); and near 

 BeiTy Wood, Aldenham ; probably the same station. 



Carduus pratensis. — Eickmansworth Common Moor; and on 

 Stanmore Heath ; but this last must, I suppose, be in Middlesex. 



Arctium majus. 



A. minus. 



A. intermedium. 



A. nernorosum. — All four have been noticed at Harefield, and 

 will almost certainly be found in the adjoining district of Herts. 



Gnaphalium sylvaticum. — Bushey Heath. Possibly in Middlesex. 



Solidago virgaurea. — A composite, supposed to be this, has been 

 recorded from Pinner Lane, under the name of JErigcron Canadense. 

 The station may, perhaps, be the same as that at Eastbury, where 

 the true Solidago has been since noticed. 



Petanites vulgaris. — Specimens of the female plant are in the 

 Kew Herbarium, collected at Munden, near Aldenham, by Mr. 

 Borrer in 1844. 



Hieracium mnrorum. — Eeported to grow on St. Alban's Abbey 

 in company with II. vnlgatum. Something else also has been re- 

 corded from walls at St. Albans as H. tnaculatum. 



" Sieracii seu Pilosellce majoris species humilis, foliis hngiorihus 

 rarius dentatis plurimis simul, flore singulari nostras. — On a dry 

 bank at the edge of a wood in a lane leading from Horn Hill to 

 Eeickmeersworth in Hartfordsh. I). Plukenet." Eay, Synopsis, ii. 

 75. From Plukenet's figure (Phytographia, t. 37). This has 

 been identified with H. horeale, of which it is rather a dwarf single- 

 headed monstrosity, with crowded leaves, than a variety properly 

 so called. The recorded stations for H. horeale and sglvnticum 

 (about Eickmansworth ; Bricket Wood Common ; and Woods by 

 Pinner Lane) deserve further examination. H. tridentatum may 

 not impossibly bo found to occur. 



Campanula rotimdifolia. — The var. montana of Syme, with oblong- 

 lanceolate lower leaves, and subsolitary flowers, was found by 

 Plukenet " about Eeickmeersworth in a dry gravel-pit." Eay, 

 Syn. ii. 158.
