THICnOMANES. 141 



Hiib. Jamaica, Sloane, Su-art:, liuncroft, Macfadym, Purdie^ ^c. Mex- 

 ico, Schirdc ct Dej)p(', (utleotti. — An elepant, very distinct, hut little under- 

 stood species, often perhaps confounded witli T. radicans, hut totally dif- 

 ferent in a variety of particulars. It lias indeed the same lonp creeping 

 caudex ; hut the frond (0 iiichcs to a fool lon<>;) is rtinarkahly thin, niem- 

 hranaceous, pellucid, ycllow-fjrccn, glossy, and truly bipinnate; the invo- 

 lucres wholly sunk in the froud. Stipes 3 — 1 or o inches long. — Linna>us, 

 Willdenow and others have referred to Plumier, t. f>3, for this plant; hut it 

 is quite different, and possibly our T. Kjinzcuiium ; though it docs not cor- 

 rectly resemble any species known to me. Sloane's figure, on the other 

 hand, is very cliaractcristic. I have only seen West Indian and Mexican 

 specimens. 



70. T. nn(/us(aiftm, Carm. ; caudex creeping slender and 

 matted, iVonds pendent? ilaccid lanceolate ])innate, pinna) bi- 

 jiinnatilid, the segments narrow-linear glabrous simple or bi- 

 fid obtuse, involucres urceolato-cylindrical sunk in the frond, 

 the mouth spreading obscurely ^-lipped, the rachis through- 

 out and stipes slender filiform terete naked. — Carm. in f.inn.

 7i. 1784. Gouga Sokoo, yia>c7ay. — Caudex short, ^ an inch to 2 inches 

 long, slender, filiform. Frond varying in length, 3 — 5 inches, very flaccid, 

 slender, graceful aud probably pendent. 



77. T. exsectitm, Kze. ; caudex creeping, fronds pendent 

 ilaccid lanceolate or oblong ])innate, pinuic bipinnatifid, the 

 segments narrow linear glabrous simple or bifid obtuse, in%'o- 

 lucres oblong sunk in the frond, the mouth sjireading scarce- 

 ly 2-lipped, the rachis winged above naked below as is the 

 whole stipes. — Kze. Anal. Pteridoyr. p. 47, t. 29,/. 2.

 L'apt. P. P. King, R.N. (in. Herb. Ilcward), Cuming, n. 13:35. Chiloe, 

 Cuming, ( Kunze J. Valdivia, Bridges, n. 800. — Professor Kunze has well 

 distinguished this species from T. angustatum, and his figure gives a good 

 representation of our smaller specimens (for they vary from 4 inches to more 

 than a foot), but the receptacle is longer than in ours, probably from being 

 more perfect. It is a larger plant generally than T. angjistatu'm, the rachis 

 is decidedly winged above, the involucres are more oblong, almost cylindri- 

 cal, but tapering at the base, and the lips are much smaller. 



78. T. trichoideum, Sw. ; caudex creeping, frond broadly 

 lanceolate tripinnate, segments linear-capillary a little broad- 

 er upwards bifid or forked, involucres terminal on short lateral 

 segments slijntate urceolato-cylindrical, the mouth spreading 

 entire, stii)es slender filiform. — Siv. Fl. Ind. Occ. p. 1741.
