L. mirabile and australe, Willd. Sp. Pl. v. 11.—Rumph. Herb. Amb. vi. t. AL fig. 1; 
Rheede, Hort. Mal. xii. 14. 
Soonderbun. Nepaul, Sikkim, Assam, Khasia, in hot valleys, alt. 500-3500 feet ; not 
common.—Distrib. South India, Ceylon, Malaya, Australia, Polynesia, Africa and its 
eastern islands. 
Var. numularifolia, (sp.) Blume, Enum. Pi. Jay. Fil. 263. Leaves elliptic obtuse.— 
L. rotundifolium, Wall. Cat. 2183 ; Roxb. in Cale. Journ. Nat. Hist. iv. 473; Hk. & 
Grey. Ic. Fil. 212. 
Malay Islands.—This is not, I believe, a North-Indian form; but Mr. Baker regards 
the whole of Spring’s 9th section (containing L. Phlegmaria and allies) as but one 
species, 
tt Leaves of the stem and fertile branches quaquaversal, of the ultimate sterile branches 
decussate, so that these branches appear flattened. 
10. L. compLanatum, Linn. Sp. Pl. 1567. Stems elongate; leaves of the ultimate 
barren branches 4-ranked, the two marginal ranks faleate oblong-linear, the dorsal 
and ventral ranks much smaller, straight, linear; peduncles long, with several 
straight catkins.—Schk. Krypt. Gew. t. 163; Hk. & Bauer, Gen. Fil. 117 4 ; Spring, 
Monogr. Lycopod. 101; Milde, Fil. Europ. 257. Z. thyoides, Humb. & Bonpl. ; 
Blume, Enum. Pl. Jay. Fil. 263. ZL. sabinefolium, Willd.; Blume, Enum. Pl. Jav. 
Fil. 263; Spring, Monogr. Lycopod. 84. 
Assam, Griffith. Khasia; Moflong, Griffith, J. D. Hooker, C. B. Clarke; Syung and 
Mumbree, J. D. Hooker.—Distrib: Java, Northern Europe, Asia and America. 
Milde (Fil. Europ. 257) doubts whether the Deccan L. Wightianwm (Wall. Cat. 2184, 
Spring, Monogr. Lycopod. 103) differs from Z. complanatum. There is now good 
material of L. Wightianum collected; the leaves on the ultimate sterile branches are 
not of two forms, and they are only very obscurely 4-ranked: the plant seems nearer 
the Malabar Z. annotinum above referred to. 
11. L. CASUARINOIDES, Spring, Monogr. Lycopod. 94 and 2nd pt. 45. Stems elongate; 
leaves of the ultimate barren branches 2-ranked, narrow-oblong, closely adpressed, 
often with a hyaline or spreading hair-point ; peduncles very short, bearing several 
curved catkins.—Hook. Ic. Pl t. 968. D. rubellum, Presl, Bot. Bemerk. 153.

Leaves on the main stem scattered, not imbricated, often hyaline. Plant rambling 
many feet; very red in Khasia. When not in fruit there is often no — foliage,
