NOTES ON JAMAICA PLANTS 225 



The synonymy cited by Linnaeus depends oh figures in Plukenet and 

 Petiver, the determination of which is doubtful, and in any case 

 does not affect the species name. 



As regards the synonyms cited under the other J -! nnean species, 

 T. Lappula, one, Plukenefs Lappula Bermudensis &c. is represented 

 by a specimen in his herbarium in Herb. Sloane, which was determined 

 by Hemsley (Bot. ' Challenger ' Exp. : Bermuda) as T. Lappula. 

 But the fruit — glabrous, 3-celled, with hispidulous spinules — is not 

 that of T. Lappula but of T. semitriloba. The other specimens that 

 we have seen from Bermuda collected by Lane, Moseley, and others, 

 are also referable to T. semitriloba, and so far we have no evidence 

 of T. Lappula occurring in Bermuda. 



The other synonym is Agrimonia lappacea &c. of Sloane. A 

 specimen in Sloane's herbarium, iv. 31. shows this to be a species 

 hitherto undescribed (T. Sloanei nob.). It has recently been collected 

 again by Ridley.

Near T. Bartramia L. and T. excisa Urb. (Symb. Ant. v. 413, 

 1908), but differs from the former in the sepals and fruit, and from 

 the latter in the form of the leaves, those of T. excisa being described 

 as " ambitu reniformibus basi excisis." Also near T. hispida A. Rich., 

 Avhich, however, has a 3-celled hispid fruit. 



Corchorus. 



Cokchorus jestuans L. Linnaeus diagnosed this species first in 

 Si/stemaed. 10, 1079 (1759) from Patrick Browne's specimen supple- 

 mented by his drawing and description (Hist. Jam. 232. t. 25, f. 1) ; 

 the specimen (without fruit) is in Herb. Linn., named C. cestuans in 

 Linnasus's hand. The capsule is described by Browne as " oblong, 

 prismatic, obtusely 3-cornered, 3-celled, corners 2-furrowed and ver- 

 rucose." The drawing of the capsule shows it terminated with three 

 bifid horns. Linnaeus in the second edition of Species Plantarum 

 (746) quotes Plukenefs diagnosis and drawing (Phyt. t. 127, f. 3) as 

 a synonym, but the plant here represented is obviously C. olitorius L., 

 as is confirmed by specimens in Plukenefs herbarium (Herb. Sloane, 

 xcv. 28 ; xcix. 37) ; Jacquin (Hort. Vindob. i. 37, t. 85) pointed out 

 that Plukenefs figure does not represent C &stuans. 



Lamarck (Encyc. ii. 104) describes C. cestuans from a cultivated 

 plant ; the figure (Illustr. t. 478) of the capsule is taken from 

 Journal of Botany. — Vol. 59. ["August, 1921.] B
