Flora of Devon and Cornwall^ hy I. W. N. Keys. ] ] 9 
It must be now nearly twenty years since that Mr. George Harper, a bota- 
nical friend of mine, told me that he had found M. alba in Catdown 
quarries. I do not remember whether or not he showed me a specimen ; 
certainly, he did not show me the habitat, and I searched in vain for the 
plant. If he really met with it, it most likely grew on some of the ballast 
heaps which at that time were numerous on the banks of Catwater, close to 
the quarries ; and I have no doubt that he was directed to the station by the 
Eev. W. S. Hore, who had previously botanized there, and who felt great 
pleasure in assisting young students. Most likely Mr. H. C. Watson 
received from the same source his information as to the occurrence of the 
plant near Plymouth {Cyh. Brit. i. 288). 
Trifolium Linn. Clover. 
T. pratense (L.)— £".5. 1770.~Pastures, fields. —D-! and C-

T. ochroleucum (L.) — E.B. 1224. — D- Near Teignmouth: Mrs. 
Gulson{siUGt. Parf. MS.) 
May there not be some mistake here ? The species is not recognised as 
Devonian in Cyb. Brit. Its south limit is there stated to be in Kent or 
Sussex ; and, according to Prof. Babington, it is restricted to dry gravelly 
soils in the East of England. 
T. incarnatum (L.) — E.B. 8. 2950. — D- Near Laira bridge, Ply- 
mouth, no doubt introduced. Near Torquay : Stew, in Rav. — C- 
Near the Lizard point (with pale* flowers=T. Molinerii Balb. T. 
Noeanum R.) : Hore (Bab. Man.) Mr. F. P. Balkwill has gathered 
specimens there this year (1867). 
T.^«m/2S«(L.)— £'.5.944.— Sandy fields.— D. Wembury; Bolt- 
* "The pale yellow variety [of T. incarnatum'], the most common in a 
truly wild state on the Continent, appears to be indigenous near the Lizard 
point."— .B. H. P.
