1. T. maritimum, L. Sea-side Arrow-grass. " Fruit 6-celled

In salt-marsh meadows and pastures ; frequent. Fl. May — September. Ft. 

 July. 1i. 



W. Med. — In salt-marshes along the Yar, as at Barnfield, &c., abundantly, 

 1844. 



Herb more rubust and fleshy than T. paluslre, and, like that, quite glabrous 

 and smooth, with the same odious scent, but more decided if possible. Root 

 creeping, tough, throwing up bunches of leaves, and emitting numerous long, 

 stout, white or reddish fibres from benealh. Stem solitary or several distant ones 

 from the same root, ascending at the base, then eiect, teretely angular below, nu- 

 merously and acuiely furrowed from the bottom of the spike to its apex, hollow in 

 the centre, from about a foot to 2 or 3 feet in height,* according to the progress of 

 the inflorescence, often purplish. Leaves hke those of T. palustre, though stouter 

 and firmer, truly scmicUindrioal, though flattening gradually to their points, 

 where they are plane, much less finely drawn out or attenuated to their obtuse, 

 rounded, often brown lips, flat and striate but not channelled above, their sheath- 

 ing bases, proportionably shorter, with the free extremity of their scariose margins 

 longer and quite entire ; decumbent at base or ascending, very commonly incurved 

 and a little falcate, pale glaucous green, their sheathing bases white or purplish. 

 Flowers more close-set and numerous than in T. palustre and rather larger, on 

 still shorter pedicels, which, however, as in that, elongate in fruit, when they 

 nearly equal those of the latter, but are rather move spreading or patent. Bracts 

 none. Perianth and stamens precisely as in T. palustre. Gerniens 6, united 

 throughout into a subglobose, hexangular, compound ovarium. Stigmas 6 dense 

 tufts of radiating, pellucid, simple bristles. Fruit erect, about 2 lines in length, 

 ovato-glohose orsubelliplical, pale whitish or yellowish brown, formed of 6 capsules 

 combined by their inner faces and attached to a common axis at their acute inte- 

 rior angle, the rounded back of each forming Jth of the circumference of the fruit ; 

 separating completely from the base ujiwards when ripe, not remaining, as in T. 

 palustre, suspended from the summit of the axis. The capsules are acutely tri- 

 angular in section, not obtusely so or even compressed as in T. paluslre ; the seed 

 tills a large portion of tbe cavity, and is fixed to the truncate bottom of the cell by 



author observed in the ' Phytologist:' — "The name for the order to which the 

 present genus belongs, Juncaginact a^, is injudiciously chosen, as liable to be con- 

 founded with Juncacea;. I would propose to substitute Triglochinaceae, as being 

 at once unequivocable and identical, seeing that Juncago was but an old word for 

 Triglochin, and used for it generically by Tournefort and others until supplanted 

 by the latter." — Phytol. vol. iii. p. 1006. Our author's order therefore is strictly 

 synonymous with that, the characters of which we have quoted, in the absence of 

 any drawn up by himself — Edrs^ 



* I have found it above 3 feet whilst the entire upper portion of the spike was 

 in flower and bud, and hence had not then attained its utmost elongation.
