1. Leaves little different from the sporangia-bracts and passing into them 
gradually. 
2. Stout, the leaves linear-lanceolate, spreading, 1 to 1.5 cm long. 
1. L. squarrosum 
2. Slender, the leaves appressed, less than 1 cm long........ 2. L. carinatum 
1. Leaves very different from the bracts, the sporangia in distinct, slender, 
elongated, simple, forked spikes. 
2; ‘eaves ovate, .5’to. 8 mmGlong ee oe ee ee eee 3. L. filiforme 
2. Leaves lanceolate, 1 to 1.5 em long, less than 5 mm wide. 
4. L. play icovtedtan 
1. L. squarrosum Forst. 
A stout pendulous epiphyte 40 to 70 cm long, once or twice dichotom- 
ously forked, the stems about 1 cm in diameter. Leaves very numerous, 
crowded, spreading, or somewhat ascending, lanceolate, acuminate, shining, 
1 to 1.5 em long, less than 2 mm wide, entire, the midrib distinct, the spikes 
stout, 5 to 12 cm long, the bracts leaf-like and little smaller than the leaves. 
Occasionally cultivated in hanging baskets, etc.; widely distributed in 
the Philippines. India to the Mascarene Islands through Malaya to Poly- 
nesia. 
2. L. carinatum Desv. 
A slender pendulous epiphyte 40 to 80 cm in length, several to many 
times dichotomously branched, the stems 2 to 3 mm in diameter (without 
the leaves) the branches somewhat 4-angled by the 4-ranked leaves or 
bracts. Leaves rather close, ascending, lanceolate, acute or acuminate, 6 
to 8 mm long. Spikes elongated, square, 3 to 4 mm in diameter, up to 40 
cm in length, simple or forked, the bracts 4 to 5 mm long, prominently 
keeled. ‘ 
Occasionally cultivated in hanging baskets, etc.; of local occurrence in 
the Philippines. India to Formosa, southward to Malaya and Polynesia. 
3. L. filiforme Roxb. 
Slender pendulous epiphytes, the stems 2 mm in diameter or less, usually 
several times dichotomously branched. Leaves ovate, acute, 5 to 8 mm 
long, 3 to 6 mm wide, acute, spreading, laxly disposed. Spikes very slender, 
simple or dichotomously branched, 5 to 20 em long, less than 2 mm in 
diameter, the bracts ovate, about 1 mm long, but little longer than the 
sporangia. 
Occasionally cultivated in hanging baskets, etc.; widely distributed in 
the Philippines, but local. India to Malaya.
