4. CYATHEA. 23 



34. C. canaliculata, W. ; unarmed or indistinctly tuberculate ; fr. glabrous, 

 bipinnate ; prim, pinnae 8-18 in. ]., oblong, acuminate, bipinnate, pinnatifid at 

 the apex ; pinnl. sessile, 1-1 J in. I., oblong, subacute, entire or serrated ; veins 

 copious, twice or thrice forked ; sori copious near the costa ; invol. at first globose, 

 then breaking down into 3-4 tolerably regular lobes ; st. and the stout main rachis 

 brown or purple-black. Rk. Sp. 1. p. 23. t. 11. B. ]3 latifolia ; larger pinnL 

 broader./^. Fil p. 24. t. 13. A. 



Hab. Mauritius and Bourbon ; Madagascar, Neivton. It is possible that this may have 

 tripinnate fronds, but my numerous specimens are not large enough to indicate if it be so. 

 The species is very distinct, but varies much in the s^ze of the pinnules. 



ff Species of India, including Ceylon and the Malay Peninsula and Islands. 

 Sp. 35-45. 



35. C. spinuloscty Wall. ; st. and main rachis strongly aculeated, often dark- 

 purple ; fr. glabrous, ample, subflaccid ; pinnl. oblong, acuminate ; lobes acute, 

 serrulate, small bullate scales on the costules beneath ; sori copious, close to the 

 costules ; invol. globose, very thin, membranaceons, fragile, soon breaking irre- 

 gularly. Watt. Cat. n. 178.* Hk. Sp. I. p. 25. t. 12. C.

36. C. crenulata, Bl. ; unarmed ; fr. bipinnate, subcoriaceous ; pinnl. oblong, 

 lanceolate, short-acuminate, 2-3 in. 1., dark, livid green, paler beneath, minutely 

 chaffy at the costse ; lobes approximate, oblong, subacute, subfalcate, crenulato- 

 serrate ; sori close to the costa ; invol. membranaceous, pale or chestnut-brown, 

 fragile, soon breaking into very irregular lobes. HJc. Sp. 1. p. 25. Mett. in Miq.

Hab. Java. This presents no very striking specific character. Mettenius, who gives 

 a very full description, 1. c. , remarks, " Indusio conditione et consistentia ab speciebus 

 antecedentibus diversa ; viz. C. Javanicci, Korthcdsii, hymenodes, Zollinyeriana, orientalis, 

 and SecheUarum." 



37. C. Javanica, Bl. ; " arboreous, unarmed ; fr. bipinnate, subcoriaceous ; 

 pinnl. lanceolate, acuminate, deeply pinnatifid, bullato-squamulose at the base of 

 the costa ; lobes linear-subfalcate, obtuso-crenulate or entire, plane ; sori 2-5, 

 parallel to the costa ; second, rachis paleaceo-tomentose ; prim, one asperulous, 

 with minute bristles." /. En. p. 245. Hk. Sp. I. p. 26. Mett. in Miq. Ann. Mus. 

 Bot. L. Bat. 1. p. 56. 



Hab. Java, Sumatra. Mettenius describes the involucres as rigidly membranaceous, 

 but breaking down into a nearly plane circular base : this is true in some of my authentic 

 'pecimens ; in others it breaks into unequally-lobed cups. Notwithstanding the careful 

 lescriptions of Dr. Mettenius of the Malayan species of Cyathea, I fear we have yet much 

 io learn with regard to their limits. 



38. C. integra, J. Sm. ; unarmed ; fr. firm-membranaceous, brownish-green, 

 laler beneath, glabrous ; prim, pinnae ample, 1^ ft. 1. ; pinnl. sessile or petiolate, 

 3-5 in. L, from a subtruncated base oblong-acuminate, pinnatifid -|-f of the way 

 ;o the costa,*broad-oblong, subfalcate, acute, serrated ; sori in 2 series, intermediate

Hab. Amboyna, and Philippine Islands. 



39. C. Sarawakensis, Hk. ; caud. 12 ft. 1. ; gen. and part, rachises smooth and 

 ;lossy ; fr. ample, glabrous, subcoriaceous, bipinnate ; prim, pinnce distant, peti- 

 >late, 20 in. 1. or more, 6 in. w., broad-oblong, pinnatifid only at the acuminated 

 ipices ; pinnl. numerous, approximate, horizontal, sessile, 4-6 lines wide, oblong- 

 icuminate, crenato-serrate, obliquely cuneate at the base ; veins approximate, 

 )i-trifurcate ; sori dorsal or, rarely in the axils of the veins, globose ; invol. a thin,
