20 AUIANTUM. 



cimen of this kind with very imperfect fructification, marked " A. Kunzei 

 Miq. (Surinam),'' I possess from Dr. Miquel. Under A.nhtusum, Kunze, 

 in ' Linnrea,' 1. c, refers to this, where he says in a note, " A. Kunzei^ Mi- 

 quel in Diiiv. Inst. Reg. Bat. a. 1843, p. 5, f. I, et Ad. hirtum, Splitz. in 

 Tydschr. voon Naturl. Gescheids, en Phys. t. 7, p. 40 (non Klotzch), sunt 

 species mihi nondum visa?." 



40. A. hirtum, Kl. ; rather small, fronds bipinnale, pinnro 

 10 — 14 or 15 linear-lanceolate acuminate patent, pinnules 

 numerous dark green glaucous and concave beneath charta- 

 ceous ditnidiately oblong very obtuse approximate villous 

 with rufous hairs beneath truncated at the superior base, 

 lowest pinnules subrhomboid, terminal one narrow trapezi- 

 form superior margin and apex crenato-serrate, lobules sori- 

 ferous, sori copious small close-placed, involucres oblong- 

 reniform often jagged at the margin, stipes ebeneous nearly 

 glabrous smooth, rachis ferruginous subtomentose. (Tab. 

 LXXXII. A.) Klotzsch, in Linnaa, xviii. p. 563. " A. termi-

 Hook.). Brazil, Ilhios, Moricand. Para, Spruce, n. 14, var. P Panama, 

 Seeinan (sterile. Pinnas glabrous). — I have drawn up my character and 

 made the figure from Klotzsch's specimen ; and all my other specimens 

 from the several localities above-mentioned precisely accord with it, save 

 the var. ? noticed from Panama, which seems to differ only in having the 

 pinnules destitute of any villosity. 



41. A. Cai/ennense, WiWd. mst. ; large, fronds bipinnate, 

 pinnge oblong-lanceolate subchartaceous acuminate patent, 

 pinnules subdimidiato-oblong (almost aparallelogram) deorsely 

 subfalcate full green very dense rather shining truncate at 

 the base, superior margin and apex coarsely crenate serrulate 

 in the sterile ones, lobides soriferous, involucres oval-oblong 

 approximate regular 9 — 12, ultimate pinnule lanceolate much 

 acuminated serrated, lowest ones flabellate, rachis stout 

 densely clothed with rusty hairs, stipes triangular black with 

 dense deciduous hairs. (Tab. LXI. A.). — Klotzsch, in Lin- 

 n(ea, xviii. p. 552. Kunze, in Linnam, 1848, p. 223.

 Sm. Surinam, Keppler. Dry sunny places, Serra de Araripo, Brazil, Gard- 

 ner, n. 1906. — ^. pinnules narrower. British Guiana, Sir R. Schornburgk. 

 Cayenne, Montague de Malveri, Le Prieur, in Herb, nostr. Tumaco, Cen- 

 tral America, Pacific side. Hinds. Jamaica, Dr. Distin. — Whether this 

 be a species or not, I feel no hesitation, (having seen an authentic specimen) 

 in considering Mr. Gardner's ' Lindsaea,' n. 1906, as identical with it, and also 

 in pronouncing some otherwise puzzling plants from Cayenne, Central Ame- 

 rica and Jamaica, to be varieties having narrower pinna. It is a rather 

 large species (frond H to 2 feet) with stipes and rachis stout, very tomentose.
