208 LINDS.EA. 



bellatc. Sori wanting.'' — T!ie figure lias to me quite the appearance of 

 small unLranchcd states of L. stricta, Dry., also an inhabitant of Mexico, 

 and is indeed the very next species which is described in the work above 

 quoted. Kunze, however, is of a different opinion, and mentions its affini- 

 ty with L. linearis, Sw., of Mew Holland, when describing that species. 



17. L. Leprieurii, Hook. ; caitdex filifonu creeping, fronds 

 oblong incnibranaceous pinnate, piinioe half-ovate acuminate 

 dellexo-falcatc truncate at the superior base which is paral- 

 lel to the obscurely winged rachis, lower vein parallel to, but 

 a little distant from, the margin, terminal pinna) with 3 acu- 

 minated lobes, sorus narrow continuous distant from the mar- 

 gin, stipes and rachis tetragonal dark glossy brown. (Tab. 

 LXII. D.) 



Hab. French Guiana, in mountainous places, M. Leprieur (Herb. Ro- 

 thery). — Plant small, scarcely a span high. Stipes dark brown, almost black 

 and glossv. Pinnules an inch or more long, decurvo-falcate, especially the 

 lower one. Lower valve of the involucre much narrower than the upper 

 which is quite foliaceous, not diftering in texture from the rest of the pinna. 

 Terminal pinna formed of 3 combined pinnae, with a main nerve running- 

 through the centre. 



18. 1a. falclformis, \ioo\s..; small tufted, caudex creeping 

 clothed with chaffy hairs, stipes very short brown and as well 

 as the rachis somewhat 4-angled, fronds lanceolate pinnate, 

 pinna? half oval-oblong obtuse falcate deflexed especially at 

 the very obtuse apex, involucre continuous marginal, lower 

 vein parallel to, but distant from, the margin. (Tab. LXIV. 

 B.) 



Hab. British Guiana, Schombimik. — Stipites tufted, very short. Fronds 

 somewhat rigid, small, with rather numerous and rather close-placed pinnce. 



19. L. crenata, Kb; caudex creeping clothed with fulvous 

 hairs, fronds erect strict rigid oblong-lanceolate pinnate, 

 pinna) approximate horizontal subcoriaceous opaque (not 

 shining) dimidiato-oblong (almost 4- sided) very obtuse sub- 

 falcate the upper margin and apex crenato-serrate with a nar- 

 row raised border or margin, the lower edge costate, sori 

 " continuous within the superior margin," stipes dark brown 

 glossy tetragonal. — K/otzsc/i, in LiniKca, 1844. p. 546. 



Hab. British Guiana, Sclmmhirgk. — It is to be regretted that this cu- 

 rious plant is not known to nie in fructification. The stipes is short, and 

 as well as the erect and straight rachis, dark brown, glossy, as if varnislied. 

 Frond scarcely a span high, oblong-lanceolate. I'innBe closely placed, ri- 

 gid, subcoriaceous, approximate, somewhat imbricating, horizontal ; the 

 lower edge constituting the costa or midrib, of the substance of the ra- 

 chis (more distinct than in any other of the EuJindscECE). The upper mar- 

 gin, and the very blunt apex especially, are crenato-serrate and edged by a 

 narrow elevated border of a Hrm cartilaginous character. I have only seen 

 it in Mr. Smith's collection, but without sori.
