 % 1. LOMARIOPSIS. 



(4a) S. areolaris, Copel., Philipp. Journ., II, 406; Lomaria areola- 

 ris, Harr., Journ. of Linn. Soc, Bot., XVI, 28; Blechnum areolars, Copel., 

 Polypod. Philipp., 90. 



Rhizome long, slender, naked, twisted. Stipes of barren fronds + 15 

 c.M. long, naked. Barren fronds ovate, 10 — 15 c.M. long, 7 — 10 c.M. broad, 

 pinnate. Pinnae 7 — 9, lateral nearly sessile, terminal stalked, linear-lanceo- 

 late, o — 8 c.M. long, 1 — 2 c.M. broad, acute, finely serrate, truncate or rounded 

 at the base. Texture coriaceous; surfaces naked; costae and veins slightly 

 chaflfy beneath; veins free, simple or forked, united at the base by a series 

 of arches ± close to the midribs, thus forming on each side a row of long, 

 narrow costal areolae. Fertile ^fronds on stipes + 30 c.M. long, the pinnae 

 narrowly linear, o^j^—^ c.M. long, rather distant. Sori protected by the specia- 

 lized, recurved, indusium-like margin when young. — Near S. palustris, Bedd. 

 I saw a plant, probably a form of this, which had the pinnae with 2 glands 

 at the base, 1 on the upper and 1 on the lower edge.

(3) A. evecta, Moffm. — This variable species is construed as 

 including several forms (considered by de Vriese as distinct species) united 

 by intermediates which are difficult of determination (*). 

 a. Recurrent veinlets present, reaching at least ^l^-way down to the casta. 

 h. Pinnae rather thick, chartaceous to coriaceous. 



c. Largest pinnulae ± 17% m.M. or more broad. (5a) A. evecta. 



(36) A. Miqueliana. 

 c.c. Largest pinnulae + 9 — i7^j^ m.M. broad. 



d. Pinnulae pruinose beneath. (3c) A. pruinosa. 



d.d. Pinnulae not pruinose beneath. 



(') Determining these forms one should bear in mind that: a, the complete fronds are 

 very large; b, the collectors commonly gather only some pinnae ol a frond; c, the gathered 

 pinnae often are those having not the largest pinnulae; d, the limit between opaque (impel- 

 lucid) and pellucid veins or veinlets is not well-marked and it is often uncertain whether a 

 transparent vein or veinlet should be regarded as an opaque or pellucid one; and e, the 

 cuneate or rounded bases of the pinnulae are not rarely 'imperfectly cuneate or rounded, 

 i. e. often + intermediate between both.
