lobes. Lateral segments unequal-sided, the upper side cut + '/,-way down 

 into erecto-patent lobes, the lower lobes shorter than the medial ones, the 

 lower side broader than the upper, deeply pinnatifid into entire, toothed or 

 lobed lobes, the lowest of which are much elongated, pinnatifid, falcate. Tex- 

 ture herbaceous; surfaces naked. Fertile fronds of the same shape, but all 

 the divisions linear, 1—1 V2 m.M. broad. — Stipes to 45 c.M. long. 



Var. minor: Dimensions '/s smaller than those of the type. 



Malaya; Salomon Isles; — var. minor: Celebes. 



(2) S. pinnata, Copeh, Philipp. Journ., I, SuppL, 146. 



Rhizome stout, erect. Stipes tufted, black-fuscous, or yellowish towards 

 the frond, clothed with a few distant, deciduous scales, 25 — 40 c.M. long, the 

 fertile fronds on the longest stipes. Barren fronds deltoid-ovate, ± 30 c.M. 

 long, ± 20 c.M. broad, pinnate, the rachis densely short-hairy. Lowest pin- 

 nae stalked, subfalcate, ovate, acuminate, pinnatifid to "/j on the way to the 

 costa, with the lobes on the lower side produced, those near the base shor- 

 ter, the edges serrate, the sinuses provided with minute setae; next following 

 pinnae sessile, higher adnate, highest connected. Texture membranaceous; 

 surfaces nearly naked. Fertile fronds ± 10 c.M. long, 2-pinnate.

 Nat. Pfl. Fam., P, 198; Acrostichum Teysmannianum, Bk., Becc, Mai., Ill, 56. 



Stipes castaneous like the rachis, naked, + 45 c.M. long. Sterile fronds 

 ohlong-rhomboidal, 45 — 90 c.M. long, 30—60 c.M. broad, pinnate. Pinnae 

 erecto-patent, the lower ones short-stalked, acuminate, S'/^ — 6 c.M. broad, 

 deeply pinnatifid nearly to the costa into numerous linear-oblong, bluiltish, 

 entire or inciso-crenate to toothed lobes 5 — 8 m.M. broad, the lower lobes 

 shorter. Texture herbaceous, firm; surfaces naked, or the costae and costu- 

 lae clothed with numerous short, gland-like hairs. Fertile fronds similar, but 

 smaller and narrower; ultimate divisions linear, ± 2 m.M. broad, united by 

 a very narrow costal wing. 



Sumba Island. 



SS. HY]\IE]VOLEF»IS, Kaulfuss. 



Sporangia densely covering the under side of the much contracted, linear 

 or spoon-shaped apex of simple fronds, often protected by the recurved edge 

 when young.
