First record. Millefolium aquaticum pennatum minus folioUs singularibus 



latiusculis flosculiis subjectis donatum. In fossa prope Lodden-bridge 



baud longe a Eedinga Oppido (Bobart), Morison, Hist. Ox. iii. 622, 



1699. A poor figure is given in section 15, t. 4, fig. 7, of the same 



work, and a very imperfect specimen, representing this record, 



which may belong to this species, is contained in Morison's Herbarium 



at Oxford. The locality, which is well within the boundary of 



Berkshire, does not now yield it, but M. spicatum occurs there. It 



was rediscovered by the author in another Berkshire locality in 



» 1890. Bobart was the first to describe it in Britain. 



4. Kennet. In Wigmoreash Pond, which is 912 feet above sea 

 level, between Walbury Camp and Gibbet Hill. M. spicatum 

 was growing with it in 1890. Enborne, Jackson, 1896. 

 o. Loddon. In a pond near Finchampstead. 

 It is only recorded from Hants and Surrey of the bordering counties. 



CAIiLITRICHE, Linn. Gen. n. 13 (Stellaria, Dill. Gen. 6). 

 [C. PALUsTRis, Linn. Sp. PI. 969 (1753)- Water Starwort 



C. verna, Linn. Fl. Sviec. ed, 2, n. 3 (1755). Sp. PI. ed. 2, 6 (1762). C. vernalis, 



Kuetz. in Linnaea, vii. (1832) 175. Stellaria aquatica, Lobel. Nyman, 



250. 



True C. palustris diflfers from C. staqnalis by its shorter erect style, and by 



its smaller frviit. I have been unable hitherto to discover it in Berkshire, 



but it is a verj' likely species to occur and should be searched for. 



Obs. Dr. Noehden recorded C. verna and C autumnalis in Mavor's Agr. of 

 Berks. Dr. Mavor says they grow in ditches, ponds, and slow streams, which 

 they sometimes mat over so as to render them passable. The two plants 

 lecorded were in all probability C stagnaUs and C. hamulata. 

 True C. palustris is reported from Surrey.] 



C. intermedia, Hoffm. Fl. Germ. 2 (1791). 



C. hamulata, Kuetz. in Koch, Syn. Fl. Germ. ed. i, 246 (1837). 

 C. Autumnalis, Huds. Fl. Angl. 2 (1762), and auct. var. but not of 

 Linnaeus.
