136 TIUCHOMANES. 



for the species from a named specimen of the late Capt. Carmichael, and I 

 liave reason to believe it to be the same with that of Bory ; but it is the 

 T. meifiltum of Kaulfuss, who has given a good representation of it. Its 

 mode of growth is very erect, with a stout caudex and rachis and finely cut 

 segments, which may be compared to a larch-tree in miniature. Stipes 

 3 — 5 inches, rising 3 or 4 together from a stout, horizontal, setose caudex. 

 Fronds (i— 7 inches high, with very close and very fine almost setaceous 

 divisions. Sori copious on the upper part of the frond. 



61. T. mijriophyllnm, Desv. ; "fronds 4-pinnate, pinnules 

 vatlier remote, secondary ones siibsecundly pinnate and ulti- 

 mate ones capillary, sori axillary, receptacles somewhat in- 

 cluded, rachis downy hairy at the base, stipes terete." Desv. 

 in Mem. Soc. Linn. Par. ii. p. 329. 



Hab. Madagascar, {Desvaux). " Frond and stipes 8—10 inches high. 

 Very near T. fceniculaccum,\)\xi different." 



G'i. T. bijidum. Vent.; "fronds bipinnate, pinnules pin- 

 natilid, segments linear all bifid at the apex and acute, rachis 

 setose." Vent, in Willd. Sp. PI. v. p. 511. 



Hab. East Indies? {WilUhnow). " In habit very like T. rigidum, but 

 sufficiently distinct in the narrow segments of the pinnules, and in all, even 

 the terminal ones, being bifid." — It is more than probable that this is one 

 of the East Indian forms of T. rigidum. Blume had probably seen an au- 

 thentic specimen, for he says, under his T. obscurum {T. rigidum P), " T. 

 bifidum, Vent, cui simillimum, differt laciniis omnibus bifidis indusiorum- 

 qiie receptaculis multo brevioribus." 



63. T. strictum, Menz. ; tufted very erect, fronds lanceo- 

 late rigid straight pinnated, pinnai approximate lanceolate 

 bipinnatifid, the segments linear obtuse loosely reticidatedy 

 involucres urceolate free, the mouth slightly spreading entire 

 not 2- lipped, the rachis margined, the stipes elongate terete 

 quite naked. — Hook, et Grev. Ic. Fil. t. 122. T. leptophyl- 

 lum, A. Cunn. Fl. Nov. Zel. in Hook. Comp. to Bot. Mag. 

 ii. p. 368. 



Hab. Dusky Bay, New Zealand, and Otaheite, Menzies. Hokianga, 

 Northern island. New Zealand, A. Cunningham. — Very distinct, first found 

 by Mr. Menzies in the southern extremity of the middle island of New 

 Zealand, and in Otaheite. This has the largest stipes and narrowest frond 

 of any of this division: the shape of the segments and the nature of the 

 reticulations most resembling the following species, T. meifolium and T. 

 gigantcum. Autlientic specimens of T. leplophi/llum of A. Cunningham, 

 in Mr. Howard's herbarium, prove that to be the same with T. strictum, 

 Menz. 



64. T. gigantenm, Bory in Willd. ; tufted .? erect very tall, 

 fronds broadly ovato-lanccolate bipinnate, primary pinna; dis- 

 tant lanceolate acuminate elongate, secondary (or pinnules) 

 ovate the lowermost superior ones applied to the rachis sub- 

 tripinnatifid, the segments linear obtuse, involucres supra
