(140) S. Junghulmiana. Spring, PL Jungh., 276. 



Shoots very small, caespitose, ascending, 2Y 2 4 cm. long, branched 

 from the base, triangular in outline, the stem very slender, yellow when 

 dry, the lower branches spreading, with 1 2 short branchlets, the higher 

 ascending. Leaves pale, whitish beneath, thin, diaphanous, flaccid; those 

 of the lower plane spreading, spaced on both stem and branches, lanceolate- 

 oblong, 2 3 mm. long, 1 2 mm. broad, subentire, or very minutely den- 

 ticulate on the upper edge, broadly rounded at the upper base, the higher 

 ones acute, the lower bluntish ; those of the upper" plane very minute, 

 lanceolate, long-cuspidate, subentire. Spikes 5 mm. long; sporophylla of 

 the upper plane oblong, acute, minutely denticulate, rather keeled, con- 

 tiguous, the higher growing gradually shorter; of the lower plane Vs as 

 long, ovate-lanceolate, adpressed, long-acuminate, paler, minutely serrulate- 

 denticulate, erected. -- A plant gathered in Java (Junghuhn No. 255), 

 which is probably the original specimen, has the lateral leaves minutely 

 serrulate on both sides, the leaves of the upper plane with the cusp 

 nearly twice as long as the blade, the macrospores pale-yellow-brown, 

 rather smooth, the microspores orange-coloured, sparingly punctulate- 

 verruculose.

(141) S. Zollingeriana, Spring, PI. Jungh., 278; Bk., Fern 

 All., 114. 



Shoots erect or ascending, caespitose, 2V 8 cm. long, lanceolate or 

 triangular in outline, branched from the base, the stem slender, moderately 

 firm, yellowish when dry, the branches erecto-patent with 3 4 short 

 branchlets, or more compound in the larger specimens. Leaves hetero- 

 morphous, pellucid; lateral leaves erecto-patent, spaced on both stem and 

 branches, ovate-oblong; of the stem 1 2 mm. long, Y 1 mm. broad, 

 bluntish or subacute, nearly equal-sided, minutely denticulate, obliquely 

 rounded at the base; of the branchlets smaller, to 1 mm. long; intermedial 

 leaves to */ as long, ovate-oblong, subequilateral, subacuminate, keeled,
