Mr. Davizs’s Determination of Three British Species of Juncus. 11 
an oval triangular shape, terminated by a short blunt point; the 
stalk of 4—6 joints. - 
This is Juncus articulatus, Fl. Brit., Fl. Herborn.; and c com- 
pressus of Sibthorp and Relhan. - Moris, s. 8. t. 9. f. 2. Scheuchz. 
931. 1. AR. Syn. 433. 8. but I cannot refer to the m PL, where 
the definition. is petalis obtusis. 
In the secoND the panicle is more branched, “the Ste oa 
more slender, and spreading, the divisions of the calyx nar- 
rower and longer, the capsule smaller, much more taper-pointed, 
and lighter-coloured; culm of fewer joints, that, and the leaves, 
less compressed. It is a taller plant, sometimes above. three, 
feet high, and it ripens later. 
This I take to be Moris. s. 8. 1.9. f. 1. certainly Scheuchzer, 
p. 334. 4. who says: “ Calami tribus quatuorve communiter ge- 
niculis distincti,——Flosculi nunc dilutids nunc obscuriüs fusci 
aut spadicei,——Vasculum seminale triquetrum, in acutum. mu- 
cronem terminatum." It is likewise J. articulatus of Relhan; 
and nemorosus of Sibthorp. 
My rurrp differs from both the former in several particulars: 
—The panicle is much lighter-coloured ; the peduncles, which 
are divaricated, and even bent back, are evidently thicker than 
those of the seconp, the panicle of which resembles this more 
than that of the rırst. Then the smallest capsule of this ;—the 
pale-coloured bunches of florets,—and particularly the elliptic 
obtuse segments of the calyx, with a broad scariose margin, 
fully distinguish it from the other two. It is, besides, a firmer 
plant, the nodes in the leaves being scarcely perceptible with- 
out a considerable degree of pressure ;—the culm and leaf are 
quite round, and it never has more than two joints in the stalk} 
I find no description of this species besides the short one in 
Fl. Brit. articulati var. 8. “ culmo erectiore, panicula ramosiori, 
A c2 floribus.
