108 HEXAND. MONOG. 



13. J. liifonlus (Toad Rush), culm dichotomous above panicled, 

 leaves filiform setaceous grooved, flowers solitary unilateral 

 mostly sessile, capsules ellipticol-ovate much shorter than the 

 very "acuminated leaflets of the perianth. Lightf. p. 185.

 HAB. Moist and watery places, especially such as have been over- 

 flowed in the winter. Fl. Aug. Q . 



From 4 6 inches high. Leaves few, slender, only one on the stem, 

 generally near the middle. The divisions of the culm, as they are 

 called, more properly, I think, belong to the panicle, at the base of 

 which are foliaceous bracteas. Very pale. Flower green, with mem- 

 branous white margins to the leaflets of the perianth. May not the 

 var. $. of Smith, the Juncus No. 13 Dill, in Ray Sijn.be the J. Ta- 

 nageja? I strongly suspect it. If so, the capsules should be as long 

 as the perianth, besides the other characters mentioned by Dill. 



11. J. tennis (slender spreading Rush), culm above shortly dicho- 

 tomous panicled, leaves linear-setaceous grooved, flowers soli- 

 tary but approximate mostly sessile, capsules nearly sphe- 

 rical shorter than the very acuminated leaflets of the perianth.

HAB. Moist mountains of Clova, D. Dun. Fl. Aug. I/ ? 



A foot or more high, approaching in many respects, as Smith observes, 

 to J. bufonius } yet really distinct. Radical leaves several. Culm 

 naked to the division near the top, where is one leaf immediately 

 beneath the foliaceous bracteas. In the axils of the forks are 2 or 

 3 large nearly sessile flowers, and two or three unilateral ones on 

 the branches. The capsule is certainly very different from that of 

 J. bufonius., and Smith does not appear to have seen it in a perfect 

 state. This plant precisely accords with specimens I have received 

 from America, through my friend F. Boott, Esq., of the J. tennis of 

 Pursh. 



15. J. uliginosus (little Inllous Rush], 'Heaves setaceous grooved, 

 flowers three together sessile, capsule obtuse longer than the 

 perianth, culm bulbous rooting," Bich. E. B. t. 801. Bich. 

 in Linn. Trans, v. 12. p. 315. 



HAB. Extremely common, Mr. Arnott. Fl. Aug. I/ . 



*' This plant has till lately been in a very unsettled state. It is not 

 vcadily distinguishable in some states from other species j but its 

 blunt capsule will enable the botanist to separate it from J. lampo- 

 carpus and acutiflorus, and, besides the diagnostic marks mentioned 

 under J. sup'mus (J. capitatus of this work) and J. subverticillatus, 

 the opaque chocolate-coloured cal. are very constant characters.'' 

 I give the character and some remarks from Mr. Bicheno's paper 

 of this species, established by Sibthorpe, and said to be so common 

 in Great Britain j but of which foreign botanists seem to be silent, 

 and with which I confess myself to be very imperfectly acquainted.
