100 18. DAVALLIA, LOXOSCAPHE. 



Hab. Polynesian Islands. M. papillosa of Brackenridge seems to belong here. 

 D. Amboynensis, Hk. Sp. 1. p. 178. t. 56. C., is apparently a reduced form of this, with 

 only the lowest pinnules cut down to the rachis. 



63. D. (Micro.) Denhami, Hk. ; rhizome creeping ; st. 4-8 in. 1., slender, 

 erect ; fr. 12-24 in. 1., 6-12 in. br., ovate, quadripirmatind ; pinnl. of the lower 

 pinnae lanceolate, 1^-3 in. 1., 1 in. br., cut down to the rachis into oblong 

 toothed segm., the lower ones \ in. 1., \ in. br. ; texture herbaceous, both surfaces 

 naked ; sori numerous, very small, terminal in the teeth ; invol. half-cupshaped. 

 - Hk. 2nd Cent. t. 47. Brack, p. 236. 



Hab. Fiji and Samoa. Near D. campyleura, but much more finely cut and thinner 

 in texture. 



64. D. (Micro.) hirta, Kaulf. ; st. strong, 12-24 in. 1. ; fr. 3-6 ft. 1., 12-24 in. 

 br., deltoid, tri- or quadripinnatifid ; lower pinnae 6-12 in. 1., 3-4 in. br., ovate- 

 lanceolate ; pinnl. lanceolate, cut down to the rachis into oblong broadly-toothed 

 lobes ; texture coriaceous ; rachis and especially the under surface pubescent ; 

 veins beneath prominently raised ; sori 2 to 20 to a segment, placed one or more 

 together at the base of the teeth. Hk. /Sp. 1. p, 181. f). proxima, Blume ? 



Hab. North of India, Ceylon, Malayan and Polynesian Islands. This has the stature 

 and habit of D. Speluncce combined with the coriaceous texture and prominent venation 

 of D. strigosa. 



65. D. (Micro.) Speluncce, Baker; st. strong, 12-18 in. 1. ; fr. 3-6 ft. 1., 12-24 

 in. br., deltoid, tri- or quadripinnatifid ; lower pinnae 6-12 in. 1., 3-4 in. br., 

 ovate-lanceolate ; pinnl. lanceolate, cut down to the rachis below into oblong 

 deeply-toothed lobes ; texture herbaceous ; rachis and under surface hairy ; veins 

 beneath neither prominent nor rigid ; sori 2 to 20 to a segment, placed one or 

 more together at the base of the lobes. Polyp., L. D. polypodioides, a and /3,

 Sp. I. p. 183. D. Madagascariensis, Kunze. 



Hab. Hindostan, ascending in the Himalayas to 1-7,000 ft., S. E. China, Ceylon, and 

 Polynesian Islands, southward to Norfolk Island, and Queensland, Madagascar, Bourbon, 

 West Tropical Africa, andMacalisberg mountains, west of Natal. West Indian Islands, 

 southward to Brazil. This is much more tender in texture than D. strigosa and hirta, 

 so much so, that the pin nee are liable to shrivel up when the plant is gathered in a hot 

 country. It resembles Dicksonia rubiginosa considerably in general appearance, and has 

 a wide geographical range. 



Loxoscaphe, Moore. Invol. forming a compressed suborbicular or cup- 

 shaped pouch at the side of the segments, which is open only at the top. All 

 decompound with linear ultimate segments. Sp. 66-69. A very natural group, 

 allied in habit to Darea, but quite different in the fructification. 



. D. (Lox.) concinna, Schrad. ; st. tufted, 3-4 in. 1., erect, naked ; fr. 6-9 

 i., 2-3 in. br., oblong-acuminate, bipinnate ; lower pinnce erecto-patent,-

 in. i. 



1^-2 in. L, ^ in. br., with simple or forked branches equalling the rachis in 

 breadth, 2-3 lin. L, \ lin. br. ; texture stoutly herbaceous, surfaces naked ; sori 

 half-cupshaped, 1 lin. br., sunk in the dilated apices of the segments. Hk. Sp. 1.

 12-18 in. L, 6-9 in. br., .lanceolate-deltoid, quadripinnatifid; pinnl. of lower 

 pinnce lanceolate-deltoid, 2-3 in. 1., 1 in. br. ; segm. cut down to the rachis with
