branches. Leaves moderately dense, spreading, secund, lanceolate, 
acute, in. long, with a distinct midrib. Spikes cylindrical, 1-2 in. 
long, erect, simple, with a stiffly-erect peduncle much longer than 
themselves ; bracts deltoid-cuspidate, 2-3 times the length of the 
capsules. 
Mauritius, in damp woods at Savanne and Grand Bassin. Cosmopolitan in the 
tropical and warm temperate zones. 
9. L. clavatum, Linn. ; Spring , Monog. Lycop. i. 89. Stem trail- 
ing to a length of several feet, with distant spreading dichotomously- 
forked branches. Leaves i in. long, linear, hair-tipped, erecto-patent, 
furnished with a distinct midrib. Spikes cylindrical, 1-2 in. long, 1-5

Mauritius, on plateaux at Nouvelle Decouverte, Bojer . Cosmopolitan"’ in tem-

We have at Kew a specimen of L. rigidum , Willd. (L. Sieberianum, Spring) in 
Sieber’s Synopsis Filicum, No. 148, labelled as Mauritian, doubtless in error, as it is 
otherwise known only in Tropical America. It has stiffly erect stems under a foot 
long once or twice equally forked, rigid linear spreading or ascending leaves in. 
long and capsules hidden in the axils of unaltered leaves all down the stem. 
2. PSILOTUM, Sw. 
Capsules depresso-globose, 3-celled, 3-valved, scattered down the 
branches in the axils of the very minute leaves. Spores marked with 
a single line. — Stems glabrous, coriaceous, simple in the lower part, 
copiously dichotomously branched upwards. The only species. 
Branchlets triquetrous .• 1. P. nudum. 
Branchlets flat 2. P. complanatum. 
1. P. nudum, Griseb. Flor. Brit. West Ind. 130. Stems 1-2 feet 
long, erect, the ultimate branchlets triquetrous, not more than in. 
thick. Leaves at most as long as the thickness of' the branches, shorter 
than the capsules. P. triquetrum, Sw. ; Bojer , Hort. Maur. 123. 
Mauritius and Rodriguez, frequent in the forests, both on rocks and trees. Cos- 
mopolitan in the tropics. 
2. P. complanatum, Sw.; Spring, Monog. Lycop. ii. 271. Stems 
1-2 long, pendulous except near the base, the ultimate branchlets flat,

the capsules placed in the teeth, and leaves represented only by a 
minute cusp to each tooth. P. flaccidum, Wall. ; Kuhn. Fit Afric.
