§ Euliypolepis. Rhizome widc-oceping, fronds ample, tri- or quadripinnatifid. 

 Sp. 1-10." 



1. II. temiifolia, Bernh. ; rhizome wide-creeping, puberuloiis ; st. 1 ft. 1., 

 strong, erect, slightly asperous, naked or pubescent ; /;•. 4-.5 ft. 1., quadri- 

 pinnatifid ; lower pinna; ovate-acuminate, 12-18 in. 1., G-9 in. br. ; piinil. lan- 

 ceolate ; scfjm. rather distant, 1-1^ in, 1., h i"* ^^'•' lanceolate, cut down to 

 the rachis into numerous linear-oblong toothed ultimate divisions ; texture 

 herl)aceous ; rachiscs tomentose, the costa and sometimes the surface beneath 

 slightly hairy and glandular ; sori 2 to G to an ultimate division, placed at the 

 sinuses of the teeth. — HI: >Sp. 2. p. 60. t. 89. C. and 90. A. II. dicksonioides, 

 Hi'. Sp. I. c. II. pallida, IIL <Sp. 2. p. G4. 



H.ab. Java, Polynesian Islands, New Zealand, Australia, Norfolk Island. — Closely 

 allied to this are a number of Javan forms, deseribed as species by Blume and Kunze, for 

 which I cannot give distinctive characteristics ; viz., C. setigera, alpina, rcsinifcra, poly- 

 podioides, javanica, and 2MUida of the former, i-udis and stenophylla of the latter author. 

 For an account of these, reference may be made to Blame's " Flora," Hooker's " Species 

 Filicum," and the volume of the "Linnfea" for 1848. H. resktens and amaurorachis of 

 Kunze are referred by Mettenius to Polijpodium rugidosum. 



2. H. distans, Hk. ; st. 6 in. high, slender, flexuose, chesnut-brown, naked, 

 slightly asperous ; fr. about 1 ft. 1., 4-5 in. br., ovate-lanceolate, bipinnate ; 

 pinnce spreading at right angles with the rachis, distant, especially the lower 

 ones, lanceolate, 2-3 in. 1., \ in. br. ; pinnl. oblong, the lower ones approaching 

 to deltoid, cut about halfway down ; texture herbaceous ; rachis scabrous but not 

 tomentose ; sori small, 2 to 4 to a pinnule, placed in the lower sinuses. — Hk. 

 Sp. 2..p.1Q. t. 95. C. 



Hab. New Zealand. — Habit of a slender form ol Atlii/rium JilLr-fcBmina, 



3. II. anthriscifolia, Presl ; st. 1-2 ft. 1., strong, erect, straw-coloured, naked 

 hut rather rough, with small raised points ; fr. ample, quadripinnatifid ; lower 

 pinnoi deltoid-lanceolate, 1 ft. or more I., 4-6 in. br. ; pinnl. lanceolate, rather 

 distantly placed, the segm. cut down to the rachis into small oblong deeply 

 pinnatifid ultimate divisions 2 lin. 1., ^ lin. br. ; texture thinly herbaceous; 

 rachis and under surface slightly hairy ; sori 2 or 4 to each of the ultimate 

 divisions, placed in the lower sinuses. — III: Sp. 2. p. 66. t. 95. A. 



Hab. Bourbon, Mauritius, Cape Colony, Fernando Po. — The fronds are said by Bojer, 

 who called h Adianium datum, to be from 10 to 18 feet in length. II. data, Fresl, 

 and //. aspera, Presl, appear to be forms of this species. This is generally a more flaccid 

 and more finely-cut plant than H. repens and tenuifolla ; but some of the Fernando Po 

 specimens have the rachis brown and very rough. 



4. II. rcpcns, Presl ; st. 1-2 ft. 1,, strong, erect, naked or puberulons, straw- 

 coloured, more or less densely prickly ; /)•. 3-4 ft. 1., quadripinnatifid ; lower 

 pinnce 1-2 ft. 1., 6-12 in. br., ovate-acuminate ; pinnl. about 6 in. 1., lj5-2 in. br., 

 lanceolate ; segm. oblong-lanceolate, blunt, cut down nearly to the rachis into 

 numerous bluntish lobes ; texture herbaceous ; rachises like the main stem ; sori 

 2 to 6 to a segm., placed at the sinuses. — Hk. Sp. 2. p. 64. t. 90. C. — /3, inermis, 

 Hk. ; St. and rachis not at all prickly. 



Hab. Tropical America, from the West Indies southward to Brazil and Peru. 



6. H. nigrescens, Hk. ; st. 12-18 in. 1., strong, erect, glabrous, rather thickly 

 armed with strong prickles ; //'. ample, quadripinnatifid ; pinnce numerous, 

 spreading from the main rachis at rigiit angles, the lowest 1 ft. 1., in. br. ; 

 pinnl. 8-4 in. 1., 1-1^ in. br., lanceolate, spreading or even deflexed ; segm. ovate- 

 oblong, cut down to the rachis below ; texture herbaceous ; rachises like the main
