TRIFOLIUM. 



folitary leaf like thofe lower doiwn. Corolla rofe-coloured, 

 longer than tlie calyx-teeth, which however gradually ex- 

 tend beyond it as the flower fades. We much doubt 

 whether this be a diftinft fpecics from the following. The 

 braBeas are very finiilar, except being pointed, and the po- 

 fition of the Jlems, as well as the form of the leaflets, are 

 known to be uncertain marks.

 Bauh. Hift. V. 2. 377. Lagopus minor, fupinus, molli et 

 compreffo capite, flore albo ; Barrel. Ic. t. 859. ) — Heads 

 terminal, folitary, globofe. Calyx very hairy, with taper 

 teeth. Involucrum of three roundiih-ovate pointlefs leaves. 

 Stems procumbent — Native of France, Spain, and Barbary, 

 in barren di-y places. Dr. Sibthorp gathered it on the 

 fhores of Greece and the Archipelago. The feeds are fome- 

 times introduced into our gardens from abroad. This is a 

 little annual fpecies, ufually with feveral ^rocwmhent Jlems, 

 three or four inches long ; in a ftarved ftate having a foli- 

 tarj' more ereft one. Leaflets inverfely heart-lhaped, with 

 a dark-purple mark. Floivers numerous, in denfe heads. 

 Corolla twice as long as the calyx, pale bluih-coloured, with 

 a long crimfon^an^^ri/; but the calyx-teeth fubfequently 

 •rife above it. The involucral leaves are like the laft, except 

 in being blunt, and are alfo accompanied by a leaf. — T. 

 piSum, Willd. n. 26. Bieberft. Taur. v. 2. 210, appears 

 not to differ from T. Cherleri, and is doubtlefs Dr. Sib- 

 thorp's plant gathered on the fhores of Greece and the 

 Bofphorus. Nothing can be more uncertain than the 

 fpots on the leaves, which gave occafion to the name ; 

 and the proportion of the corolla to the calyx depends on 

 the period of examination. Barrelier faithfully reprefents 

 it longer than the calyx in Cherleri, when the flower is 

 in perfeAion. 



33. T. fphitrocephalum. Round-headed White Trefoil.

Heads terminal, folitary, globofe. Calyx very hairy, with 

 taper teeth, twice the length of the corolla. Involucrum 

 of three rounded leaves. Stems procumbent. — Native of 

 fields in Barbary, near Mafcar. Desfontaines. Very like 

 the laft, except its little white corolla, fliorter than the 

 ealyx. The citation of Barrelier, copied by Willdenow 

 from Desfontaines, is the very fame which, in the preceding 

 page, he had tranfcribed from I.,inna:us, though lefs exaftly 

 given by the latter. The proportion of the corolla does not 

 anfwer to this, but to T. Cherleri, which may very probably 

 have occafionally, as Barrelier fays it has, a white flower. 

 We fhould hardly fcruple to reduce thefe three laft de- 

 fcribed, with piaum, to one fpecics.

 a correft idea of thefe three laft fpecies, from the above 

 charafters, which fuit equally well a number already known, 

 to which the author appears never to have adverted. We 

 merely regifter thefe plants here for future inquiry.
