as to justify the species being placed in § Lilobruchia. (See Pi. IJ'allichiana, 

 Ag., at our p. 206, 11. 70.) 



I would observe that I have more confidence in the several descriljcd species 

 I have brought as synonyms under Pi. triparlila (and 1 possess, fortunately, 

 authentic specimens in my herbarium) than 1 have in the two varieties I have 

 made — /8 and 7. The first, from Java, has a form of pinnae and segments almost 

 approaching those of P/. ji;orfo7;/(yWa (our next species), but the texture is much 

 thinner ; and that is, I believe, a native only of tropical America : the second 

 var. 7 (Tab. CXXXVIII. IJ), from the Feejee Islands, has very much the 

 habit and structure of Pi. (Eupteris) quadriaurila, and of PL (Campteria) biau- 

 rita, but the venation is quite that of the present species. The Society Islands 

 plant, also referred there, has a peculiar habit, but the frond is sterile and the 

 segments serrated. 



110. Pt. (Litobrochia) podopliylla, Sw. ; fronds ample ter- 

 nate suljcoriaceous glabrous, lateral branches 3-4-partite, 

 intermediate one simply pinnate, ultimate pinnee or pinnules 

 petiolate broad-linear acuminate deeply and regularly pin- 

 natifid, segments approximate dimidiato-oval falcate acute 

 (scarcely mucronate) serrate at the apex, sinuses rounded, basal 

 veins monoarcuate, tertiary series of areoles marginal, stipes 

 very stout submuricated near the base and as well as the 

 rachises tawny glossy. — Siv. Syn. Fil. p. 100. Willd. Sp. PL

 (var. minor). Bogota, Hollon, n. 50. Ecuador, Jameson. Ocaiia, 4-5000 feet 

 elev., Schlim, n. 661. — This is a very fine and really veiy characteristic species, 

 figured by Patrick Browne in his History of Jamaica, published more than a 

 century ago. It was for a long time supposed to be peculiar to Jamaica, but the 

 researches of travellers prove it to be not uncommon in the northern portion of 

 South America. The form of the pinnules and segments of the Pt. propinqua, 

 var. Cumingiana, Ag. (Pt. apicalis, Liebm.), often resembles these, but the habit of 

 the two is very diflferent ; our plant is of a firm and rigid texture, with very long 

 straight pinnated pinnae, narrower pinnules, almost quite sessile, and muticous or 

 nearly muticous and more falcate segments. The primary branches or rachises 

 are thicker than the human finger, very smooth, rich tawny colour. 



111. Pt. (Litobrochia) longibracliiata, Ag. ; "fronds ter- 

 nate, lateral branches 2-3-partite and as well as the inter- 

 mediate simple one pinnate, pinnfe subpetiolate ovato-lan- 

 ceolate pinnato-partite, segments lanceolate falcate nearly 

 entire, basal veins forming a single arc, the fourth and fifth 

 areole marginal," Ag. Sp. Gen. Pterid. p. 75. — Pt. aculeata,
