103. SELAGINELLA. As. PLEIOSTELICAE. 207 



leaves. Leaves of the lower plane oblique, subfalcate-oblong, subacute, 

 entire, unequal-sided; of the branchlets rather close, ascending, the upper 

 base cuneate, auriculate, the auricle revolute, the lower base produced, 

 with a rounded corner, the margine entire, pellucid, the largest leaves 

 3V4 mm. long, Vk mm. broad; of the stem distant, horizontal, to 7 mm. 

 long, cordate and auricled on both sides at the base, with the upper 

 auricle the largest; leaves of the upper plane entire, erect; of the branch- 

 lets imbricate, falcate-ovate, subinequilateral, acuminate, pellucid-margined, 

 pellucid-dotted, decurrent at the outer base, cuneate at the inner base; 

 of the stem distant, oblong, 5. 'A mm. long, 2 'A mm. broad, acute, truncate- 

 cordate at the base. Spikes 5 — 35 ram. long, rather square, I'A — 2 mm. 

 diam.; sporophylla subisomorphous, equal-sided, ovate, shortly acuminate, 

 entire, pellucid-margined, keeled, the ventral ones somewhat larger than 

 the dorsal, and paler, the largest IV2 mm. long, 1 mm. broad; macrospores 

 fulvous, whitish when dry, verruculose on the basal side; microspores 

 yellow, provided with stipitate-capitate projections on the basal side. — 

 Specimens occurring in the Buitenzorg Herbarium and probably belonging 

 to this species differ from Hieronymus' diagnosis in having the shoots 

 partly independent (young forms?), partly springing from a divaricating- 

 scandent main stem (adult forms?), with the stems 3 — 5-stelical, if 3- 

 stelical, then commonly with a tendency to become 4-stelical, with the 

 lateral leaves spreading and very remote on the main stem, remote on 

 the principal rachises, subascending and approximate or contiguous on 

 the branchlets, not positively auricled but conspicuously plicate on the 

 upper side at the base and therefore apparently revolute-auriculate, the 

 macrospores densely rotundate-verruculose, the microspores white, yellowish 

 or pale-orange, provided with densely crowded projections which are 

 either narrowly subcylindrical or coarsely verruciform, whether or not 

 thickened (clavate or capitate) at the tip. 



Forma typica. — Borneo, Snmbawa (?). 



War. Iiiinidifolia: Axillary leaves attached by a basal tume- 

 faction, the lowest relatively small, obliquely broadly deltoid-ovate, 

 unequal-sided at the base, the following growing gradually larger and 

 more lanceolate-ovate, the higher growing gradually smaller. — Amboina.

 Shoots probably large, pinnately compound, the stem 3-stelical, 

 straminjeous, smooth, the main rachis subterete, when dry slightly 2-
