A SYNOPSIS OF THE GENUS SELAGINELLA. 23 



IcBvigata Spring Men. ii. 137. — Lycojwdimn IcBvigatum Willd., non 

 Lam. — L. Willdenovii Desv. ; Hook. & Grev. Ic. Fil. t. 57. — L. 

 peUucUlum Desv. — L. hicolor and ciBsium-arhoreum Hort. - — • Stems 

 climbing to a lengtli of 12-20 ft. or more ; pinnae spreading, 

 deltoid, reacliing a length of 1-2 ft., the pinnules deltoid and 

 decompound, the ultimate branchlets short and contiguous. 

 Leaves of the lower plane crowded, ascending, ovate or oblong, 

 l-12th to l-8th in. long, green with a tint of blue, moderately firm 

 in texture, not ciliated, obscurely petioled, cordate on both sides at 

 the base, not imbricated over the stem ; leaves of the upper plane 

 one-third as long, oblique oblong, acute, not cuspidate. Spikes 

 square, ^-1 in. long, f lin. diam. ; bracts suborbicular, with a 

 short cusp, scarcely larger than the sporangia. 



Hab. East Himalayas, Philippines, Cochin China, Malay 

 Peninsula and Isles. Well known in cixltivation. I have not 

 seen the Brazilian plant referred here by Spring ; his African 

 locality refers to S. scandens. 



211. S. EXALTATA Spring Mon. ii. 145. — Lycopodium exaJtatiun 

 Kunze. — Stems climbing to a length of 50-GO ft. ; pinna; deltoid, 

 reaching a length of 3-4 ft. ; pinnules lanceolate, with numerous 

 erecto-patent simple parallel tertiary branchlets seldom above an 

 inch long. Leaves of the lower plane contiguous, oblong-lanceolate, 

 falcate, acute, l-12tli to l-8th in. long, bright green, moderately 

 firm in texture, nearly equal-sided, not ciliated, nearly truncate at 

 the base, not imbricated over the stem ; leaves of the upper plane 

 very small, oblique oblong, shortly cuspidate. Spikes square, 

 ^-1 in. long, f lin. diam. ; bracts broad ovate, little longer than 

 the sporangia, strongly keeled. 



Hab. Forests of Tropical America from Panama to Peru. 



212. S. usta Vieill., n. sp. — Stems 9-12 in. long, erect, simple at 

 the biise, compound in the upper three-quarters, the branches 

 erecto-patent, the lower simple or little compound, the upper short, 

 rhomboid, copiously compound. Leaves of the lower plane 

 crowded, erecto-patent, ovate or oblong, subacute, i lin. long, 

 bright green, rigid, dilated, cordate, serrulate, and imbricated over 

 the stem on the upper side at the base ; leaves of the upper plane 

 one-third as long, oblique oblong, acute, much imbricated. Spikes 

 square, J-^ in. long, ^ lin. diam. ; bracts ovate-cuspidate, acutely 

 keeled. 



Hab. New Caledonia, on mountains near Wagap, Vieillardl 

 Puncher ! 



213. S. Arbuscula Spring Mon. ii. 283. — Lycopodium Arbuscxda 

 Kaulf. — Stems 4-6 in. long, erect, simple in the lower third or half, 

 decompound iipwards, with deltoid crowded ascending branches, 

 the ultimate branching midAvay between pinnate and flabellate. 

 Leaves of the lower plane crowded, ascending, ovate-rhomboid, 

 subacute, ^ lin. long, bright green, firm in texture, rather pro- 

 duced, broadly rounded, denticulate, and imbricated over the stem 

 on the upper side at the base ; leaves of the lower plane one-third 

 as long, oblique ovate, acute, much imbricated. Spikes short, 

 square, ^ lin. diam. ; bracts ovate-cuspidate, sharply keeled.
