250 APPENDIX. 103. SELAGINELLA. 



short-acuminate, the upper base plicate-auriculate, the lower base truncate- 

 cordate to truncate-cuneate, the largest leaves 3 mm. long, I'A mm. 

 broad; of the branchlets smaller, blunt or bluntish, not or only slightly 

 phcate on the upper base; intermedial leaves erect, remote on the 

 secondary rachises, imbricate on the ultimate branchlets; of the secondary 

 rachises falcate-oval, bluntish, obliquely truncate-subcordate at the base, 

 to 2 mm. long, to ^U mm. broad; of the branchlets smaller, bluntly short- 

 acuminate, the outer base rotundate-truncate, the inner base narrowed. 

 Spikes sohtary, 'A — IVz cm. long, I'A mm. diam.; sporophylla rather 

 broadly deltoid-ovate, shortly acuminate, hardly keeled, entire or subentire, 

 or obsoletely denticulate towards the base; macrospores whitish to dark- 

 yellow-brown, densely verrucose; microspores whitish or cream-yellow, 

 densely verruculose, the projections tuberculiform or shortly cylindrical, 

 the latter not rarely thickened at the apex. — A form received as var. 

 mindorensis Hieron. differs from the type principally by its proportionally 

 longer and narrower leaves on the stem and principal rachises.

Shoots ascending or erect, to 100 cm. long, the lower part simple, 

 stipitiform, to 4 mm. thick, smooth or somewhat roughish, 5 — 9-stelical, 

 laterally grooved when dry, greenish, stramineous or pale-brown, the 

 upper part copiously 3-pinnate or sub-4-pinnate, not rarely provided vrith 

 accessory pinnae springing from the axils of the pinnae ; pinnae ascending, 

 rather remote, to 25 cm. long by 7V2 cm. broad, the rachis 5 mm. broad 

 including the lateral leaves; accessory pinnae articulated at the base; 

 ultimate branchlets 8 — 4 mm. broad at or towards the base, narrowed 

 gradually towards the apex. Leaves entire; leaves of the stipe very 

 remote, subisomorphous, erect or suberect, nearly straight or falcate, 

 oblong-ovate or triangular-oblong, bluntish or subacute, 2-auriculate at the 

 base, the auricles more or less hamate-incurvate, the largest leaves to 

 8 mm. long, to Vi as broad; leaves of the branches heteromorphous; 

 axillary leaves 2-auriculate at the base, the lower broadly deltoid-cordate 

 or ovate-cordate with the auricles slightly incurved, the higher cuneate- 

 spathulate or cuneate-obovate with the auricles plicate; lateral leaves 

 approximate or contiguous, subspreading or suberecto-patent; of the 

 secondary rachises falcate-ovate, unequal-sided, bluntish to subacuminate, 

 the upper side cuneate-rotundate in the lower half, auricled at the base,
