Shoots erect, the upper part pinnate, the stem 3-stelical with a ten- 

 dency to become 4 5-stelical, grooved when dry; pinnae linear-lanceolate, 

 15 20 cm. long, 2 4 cm. broad; pinnulae ascending, to 4 cm. long, the 

 largest pinnate with 13 branchlets on a side; branchlets to 2 cm. long, 

 4 5 mm. broad including the lateral leaves. Leaves heteromorphous; 

 lateral leaves remote and horizontal on the stem, close to imbricate and 

 ascending on the branchlets; of the stem triangular-oblong, nearly straight, 

 3 4 mm. long, acute, entire, unequally truncate-cordate at the base, 

 broadest on the upper side, the upper auricle incurved; of the ultimate 

 branchlets falcate-oblong, the largest 3 mm. long, Y as broad, subacute, 

 entire, the upper side rather pellucid-margined, subcuneate in the lower 

 part, conspicuously plicate-auriculate at the base, the lower side truncate 

 at the base; intermedial leaves erect, much smaller; of the stem acute, 

 obliquely truncate-cordate at the base; of the branchlets acute or acuminate, 

 nearly longitudinally adnate at the base, the inner side straight, the 

 outer side rounded, pellucid-margined, decurrent-cuneate at the base.

 v. A. v. R., Bull. Btz., 1914, XVI, 52; S. Willdenowii, A. Br., MS. 



Shoots springing from a scandent, 5 8-stelical main stem, pinnately 

 compound, the lower part simple, orchraceous, the stem 3-stelical; pinnae 

 3 4-pinnate, with ovate or flabellate pinnulae. Leaves of the stem erect, 

 oblong, subobtuse, with the base varying from rotundate-cuneate to 

 narrowly incurvate-2-auriculate ; leaves of the branches heteromorphous; of 

 the lower plane rather spreading, oblong, subfalcate, bluntish or subacute, 

 entire, nearly equal-sided, rounded and more or less plicate on the upper side 

 at the base, truncate-cuneate on the lower side at the base; of the upper 

 plane adpressed, lanceolate, oblique, acuminate, the point bluntish, entire, 

 the base more or less rounded on the outer side. Spikes numerous, 2 1; 2 4 

 cm. long when fully developed; sporophylla triangular, shortly acuminate.
