Mr. Davies's "Determination of Three British Species of Juncns. 11 



an oval triangular shape, terminated by a short blunt point; the 

 stalk of 4 — 6 joints. 



This is JuNCUs articulatiis, Fl. Brit., Fl. Herborn.; and co/n- 

 presstis of Sibthorp and Rellian. Moris, s. 8. t. 9.f. 2. Scheuchz. 

 331. J. J?. Sijn. 433. 8. but I cannot refer to the Sp. PL, where 

 the definition is petalis ohtusis. 



In the SECOND the panicle is more branched, the branches 

 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. t. 9. f. 1. certainly Scheuchzer, 

 p. 334. 4. who says : " Calami tribus quatuorve communiter ge- 

 niculis distincti, — Flosculi nunc diluliCis nunc obscurii!is fusci 

 aut spadicei, — Vasculum seminale triquetrum, in acutum mu- 

 cronem terminatum." It is likewise J. articulatus of Relhan ; 

 and nemorosus of Sibthorp. 



My THIRD 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 second, the panicle of which resembles this more 

 than that of the first. 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. (2. " culnio erectiore, panicula ramusiori,
