of Guildford, Surrey (Honorary Secretary of the Surrey Natural His- 

 tory Society), and Mr. G. Maw, of Richmond, Yorkshire, were elected 

 members. Mr. James Hussey presented a specimen of the Phalaris, 

 from a field near Swanage, Dorsetshire, found by him in July last, 

 reported as P. utriculata {Litm.) in 'London Journal of Botany,' Sep- 

 tember, 1847; but which Mr. Hewett Watson considers to be per- 

 haps rather Phalaris paradoxa {Linn.), of which he possesses no 

 authentic specimen for comparison with the Dorset example. Mr. 

 Borrer presented specimens of Malva verticillata (Z.), (Phytol. ii. 934).

Description of Hieracium heterophyllum, a Species new to Science. 

 By James Bladon, Esq.* 



Hieracium heterophyllum, Bladon's MSS. — Leaves all sessile, cau- 

 line, lowest lanceolate, upper ovate acuminate. 



Situation. — Woods, hedge-banks ; very rare in open ground. 



Time of Flowering. — Middle and latter end of August and Sep- 

 tember. 



The height of the plant varies very much, from ten or twelve inches 

 to three feet and a half, or more : the fibres of the root are stout, cy- 

 lindrical, not tapering, from two to six inches long; stem stout, at the 

 base of the larger plants ^ of an inch in diameter, striated, very brit- 

 tle, internally filled with shining, rather largely cellular pith, thickly 

 clothed with slender, whitish, downy or silky hairs, intermixed with 

 a few dark ones, from one to two lines in length, erect, spreading, or 

 a little deflected, springing from an enlarged, oblong, glandular base, 

 close to the surface of the stem a thinly scattered, arachnoid pubes- 

 cence, which, being generally darkish coloured, gives a smoky appear- 

 ance to patches on the plant, especially as the stem and branches 

 are very apt to have one side clouded with purple. In the branch- 

 ing of the stem it very much resembles maculatum, the smaller plants 

 only bearing six or eight flowers, while the larger ones have axillary 

 branches down to the middle of the stem. 



Leaves various, none radical, all cauline (thus in an early stage 

 bearing a very difierent appearance from murorum and maculatum,
