Var. A. maeilenium, Kunze. — All parts stronger, stiffer, thicker, 

 raehis margined, 1 \ li. w. ; pinnse subentire lobed or pinnatifid on both 

 sides at the base ; segments ovate ; sori abundant, more divergent from 

 the midrib. — PL 111. t. 46. 



Yar. A. rigidum, Sw. — Resembling the type in texture, &c , but 

 pinnae pinnato— pinnatifid on both sides within. —A. longipinnatum, 

 Tourn. 



Var. parvulum, Jenm. — Fronds half the size, pinnae ineiso-serrate or 

 pinnatifid, cuneate and equilateral at the base. 



Common in woods and forests and more open places, on trees, decay- 

 ing logs and on rocks from the lower hills up to 5,000 ft. alt. ; highly 

 variable, of which beside the varieties described there are numerous 

 well marked forms. The pinnae vary from quite entire and equila- 

 teral to deeply pinnatifid or fully pinnate, the commonest form per- 

 haps being that which is freely serrated and having a single free lobe 

 on the upper interior base. The texture varies as much as the form. 

 Though easily recognised in any of its forms, the more compound 

 clearly connect it with fragrans. The plants spread into wide masses 

 by means of viviparous buds on threads or fibres from the rootstock. 



29. A fragrans, Sw. — Stipites erect, gray- green, channelled, 3-6 

 in. 1. naked, tufted from a small upright scaly rootstock ; rachis similar ; 

 flattened in the upper part ; fronds ovate-lanceolate, bi-tripinnate, 6-10 

 in. 1. 3-5 in. w. broadest at the base, very acuminate, chartaceous, light 

 green, naked, highly fragrant ; pinnae spreading obliquely, the shape 

 of the fronds, lower petiolate and usually larger, 2-3J in. 1. 1-2 in. w. ; 

 pinnulae lanceolate, stipitate, lobed or fully pinnate on both sides, the 

 largest f-1 in. 1. \— \ in w. situated on the superior base ; final seg- 

 ments ovate-oblong or lanceolate, 2-4 li. 1. 1-2 li. w. sharply dentate 

 round the outer part, and also the sides of the larger ones, acute, base 

 cuneate; veins pinnate in the larger, once or twice forked in the 

 smaller segments ; sori 1-1J li- !■ 011 0Iie or bo.th sides of the midveins 

 of the segments, and sub-parallel therewith ; involucres pale, thin.- — 

 Hook, and Grev. Icon. Fil. t. 92. 



Var. A. fceniculaceum, H. B. K. — Fronds tripinnate, finely cut, the 

 ultimate segments narrow, linear. A. delicatulum, Pr. 



Frequent in forests and sheltered, moist situations on logs 

 and stones, especially near streams, from 2,000-5,000 ft. alt. As 

 mentioned under auritum, the simply bipinnate forms of this 

 species are not very clearly marked from the most compound state of 

 that. Generally, however, this is well distinguished by its more 

 multifid state, and the sweet fragrance it emits in drying. The var. 

 is most common at the higher elevations.
