APPENDIX. 103. SELAGINELLA. 247 



with 13 branchlets on a side; ultimate branchlets 2V* mm. broad. 

 Leaves heteromorphous ; lateral leaves remote on te stem, less so on the 

 branches, whether or not contiguous on the branchlets; of the stem 

 oblique-ovate, horizontal or spreading, bluntish, unequal-sided, the upper 

 side pellucid-margined, minutely serrulate, broadly rounded or subcordate 

 at the base, the lower side subentire, or obsoletely serrulate-denticulate 

 towards the apex, truncate-rotundate at the base, the largest leaves 

 2V mm. long, IVz mm. broad; of the branchlets more oblique, smaller, 

 nearly equal-sided, rotundate-cuneate at the base; intermedial leaves erect; 

 of the stem ovate, more or less sparingly serrulate, narrowly pellucid- 

 margined towards the shortly cuspidate-acuminate apex, the cusp V< Vs 

 as long as the blade, the base obliquely rounded or subcordate, the 

 largest leaves 1V mm. long; of the branchlets smaller, with the cusp 

 proportionally longer. Spikes solitary, short, 1V mm. broad; sporophylla 

 of the upper plane spreading, oblong, subacute, minutely serrulate, keeled, 

 narrowly pellucid-margined on the upper side, to 2 mm. long; of the lower 

 plane erect or suberect, deltoid-ovate, acuminate, minutely serrulate ; macro- 

 spores yellowish-white or yellow, opaque, very minutely punctulate-verru- 

 culose, nearly smooth; microspores minium-red or orange, the projections 

 crowded, tuberculate or subcapitate. A duplicate of Elmer's No. 14267, 

 received as S. Wormskioldii Hieron., agrees nearly absolutely with this.

Hieronymus gives no description of this. A duplicate of Elmer's 

 No. 14267 differs from that, mentioned under S. Eschscholtzii Hieron., in 

 having the stem 7 mm. more or less broad including the lateral leaves, 

 the ultimate branchlets 3 3Vz mm. broad, consequently the lateral leaves 

 larger, those of the stem 3V mm. long by 2 mm. broad, the macrospores 

 more distinctly provided with numerous minutely verruculiform or shortly 

 ruguliform projections.

 2045; var. obtusifolia, Hieron., 1. c., 2046. 



War. brevifolia: Lateral leaves shorter, oblique-ovate, less 

 unequal-sided, subacute; spikes somewhat narrower, 2 mm. broad; sporo- 

 phylla of the upper plane shorter, subacute. Luzon, Negros.
