38. ASPLENIUM, EUASPLENIUM, 205 



described the form with simple pinnae. A. cyrtopteron and Jtabellatum of Kunze have 

 them deeply lobed and pinnatifid, especially in the lower half, whilst the plant called 

 rhizophorum by Swartz is fully bipinnate, and A. rachirhizon, Kaddi, and A. amabile, 

 Liebm., have distinctly separated oblong- rhomboidal pinnules again deeply cut iato- 

 narrow segments. 



76. A. anisodontum, Presl ; st. tufted, firm, erect, grey, naked or slightly 

 fibrillose ; fr. 12-18 in. 1., 4-6 in. br., with numerous horizontal or subfalcate 

 sessile pinnae on each side, which are 2-3 in. 1., ^ in. br., the point acuminate, 

 the edge inciso-crenate, the base on the upper side auricled and narrowed rather 

 obliquely, on the lower side obliquely truncate ; texture subcoriaceous ; rachis 

 firm, erect ; veins oblique, mostly once branched ; sori parallel, in 2 regular rows, 

 reaching nearly from the midrib to the edge. Hk. Sp. 3. p. 153. 



Hab. Java and Philippines. 



77. A. contiguum, Kaulf. ; st. tufted, 6-9 in. 1., firm, erect, chesnut-brown, 

 naked ; fr. 12-18 in. L, 4-6 in. br., with 20-30 horizontal subfalcate pinnae on 

 each side, which are acuminated at the apex, the edge more or less sometimes 

 deeply inciso-serrated and slightly lobed, the base narrowed suddenly, and some- 

 times auricled on the upper, obliquely truncate in a curve on the lower side ; 

 texture subcoriaceous ; rachis firm, naked or slightly villose, chesnut-coloured ; 

 veins oblique, obscure ; sori close, copious, falling considerably short of the 

 margin. //. JSp. 3. p. 156. t. 194. 



Hab. Sandwich Islands, Philippines, Neilgherries. The alliance of this and the pre- 

 ceding is with A . falcatum, but the fronds are narrower, and the sori more uniform. 



78. A. hirtum, Kaulf. ; st. tufted, 2-4 in. L, strong, erect, brownish, deciduously 

 fibrillose ; fr. 12-24 in. L, 4-8 in. br., with very numerous horizontal pinnae on 

 each side, which are 2-3 in. 1., J- in. br., the point acuminated, the edge broadly 

 not deeply toothed, the base on the upper side conspicuously auricled, on the 

 lower side rather suddenly but obliquely narrowed ; texture coriaceous ; rachis 

 dark-coloured, strong, more or less fibrillose ; veins oblique, inconspicuous ; sori 

 in 2 regular rows, which fall considerably short of the edge. Hk. Sp. 3. p. 149. 

 t. 191. 



Hab. Mauritius, Madagascar, Seychelles, Malayan Peninsula and Islands, Hong-Kong, 

 the Philippines, Ladrones and Solomon Islands. This has the simple veins and regular 

 sori of A , lineatum and longissimum, but the pinnae are unequal-sided. A . induratum, 

 Hk. 2nd Cent. F. t. 61, from Fiji, seems to be only a small form of this with blunter 

 pinnae. A . pellucidum, Lam., is apparently this species ; and if so, that name (a very 

 inappropriate one) is the oldest. 



79. A. hastatum, Klotzsch ; st. tufted, 4-6 in. L, firm, erect, greyish, scaly 

 below ; fr. 6-12 in, L, 3-4 in. br., oblong-lanceolate, with 8-12 horizontal sub- 

 sessile pinnae on each side, which are 1^-2 in. 1., about ^ in. br., the point acu- 

 minate, the edge deeply crenato-dentate throughout, the two sides unequal, the 

 upper one narrowed at nearly a right angle, the lower one very oblique ; texture 

 subcoriaceous ; rachis compressed ; veins obscure, very oblique ; sori distant, 

 falling short of both edge and midrib. //. Sp. 3. p. 116. 1. 172. 



Hab. Columbia and Ecuador. A.fragrans, Hk. Ic. t. 88, is a small Andine form with 

 a winged rachis. This is very near A.firmum and awiculatum, but is thicker in texture. 

 The Chinese A. cnnicaule, Hance, is said to be like this, but to have a wingless rachis 

 clothed like the stem with long lanceolate vinose scales with a filiform point. 



80,. A. enatum, Brack. ; st. tufted, 6-8 in. 1., firm, erect, naked ; fr. about 

 1 ft. 1., 4-5 in. br., with 9-15 pinnae on each side, which are 2-3 in. 1., i-f 

 in. br., the point acute, the upper part bluntly crenated, the two sides very 

 unequal, the upper rounded or narrowed suddenly at the base, the lower
