Hab. St. Catherine, Brazil, Macrae, Becchey, Tweedie. S. Brazil, Cha- 

 misso. Rio, Dmujlas ; at San Gaetano, Gardner, n. 5326. — Kaulfuss first 

 doscriltcd this species, and was at some pains to distinguish it from T. si- 

 nuosinn, to which, it must be confessed, it is too nearly allied. It diflfcrs in 

 the more delicate texture, more hairy fronds, which are more attenuated at 

 the apex, with long^er, deeper, and more divided so<^ments, always more or 

 less glaucous : and the characters now mentioned are constant in my speci- 

 mens from several localities. 



25. T. Ankersii, Parker in Hook, et Grev. Ic. Fil. ; caudex 

 exceedingly long creeping more or less tomentose, fronds nu- 

 merous distant nearly sessile broadly lanceolate subacuminate 

 obtuse at the base deeply pinnatifid, the segments oblong ob- 

 tuse angulato-dentate the lowermost sometimes auricled at 

 the base or subpinnatifid, involucres subcylindrical pedicel- 

 late from the apex of a tooth and solitary at the superior base 

 of each segment or numerous along the margins. — Hook, et 

 Grev. Ic. Fil. /. 201. 



Hab. Trunks of trees, British Guiana, C. S. Parker. — Allied in habit to 

 T. hravhypus, but very distinct, with the segments undivided. Caudex 

 cree])ing apparently to a very great length, 2 feet and proV.ably nnuh more, 

 simple or branched. Fronds numerous but distant, 3 — t inches to a span 

 long, membranaceous yet tolerably firm, turning nearly black in drying. 

 Veins pinnated, simple. Receptacles long, much exsertcd. 



20. T. hrachijpufi, Kze. ; caudex much elongated creeping, 

 trends numerous nearly sessile flaccid ])rocumbent, ovato-ob- 

 long bipinnatifid, the segments all patent, jirimary divisions 

 oblong, secondary bi-trifid, segments rather acute costa root- 

 ing, involucres terminal on the ultimate segments cylindrical 

 attenuated at the base completely exsertcd and jicdicellatc, 

 the mouth short spreading scarcely 2-lii)ped, the receptacles 

 fdiform much exsertcd. — Kze. PI. Cn/pl. Poopp. p. 105. T.
