EUCEPHALOZIA . 151 



cortical cells about 10, large, pellucid, inner about G in diam., smaller 

 subopaque. Lower leaves smaller and distant, upper larger and 

 subimbricate, diagonal at base or where closer, almost transversely 

 inserted, ovate-orbicular, bilobed to about the middle, concave, 

 sometimes complicate, segments connivent or patent, ovate- 

 lanceolate or subtriangular, postical acute, antical a little 

 narrower, sub-acuminate, sometimes shortly apiculate ; cells rather 

 large, 4-, 5- and G-sided, pellucid, no trigones or thickened angles. 

 Stipules wanting, except rarely on the female flowers. Inflor- 

 escence clado-acrocarpous ; branches ? very short, rarely more or 

 less elongate. Bracts about 3 pairs, innermost almost 3 times 

 longer than the leaves, partly free, to the middle bilobed, segments 

 lanceolate acuminate, entire or towards the base 1-2 spinose, 

 rarely sublaciniate; bracteole similar; sub-bracts smaller, roundish; 

 sub-bracteoles also smaller, lanceolate, spinulose, rarely bifid, 

 sometimes obsolete. Perianth 4 times longer than the leaves, 

 linear, prismatic, or subfusiform, mouth constricted or rarely 

 open, denticulate, setulose or ciliolate ; at first tricarinate at 

 the base, when older subterete, above trigonous, areolation lax, 

 pale green or white, sometimes below of a beautiful purple colour, 

 apex canescent, the whole length (except at the very base, which 

 is 2, 3 cells thick) composed of a single layer of cells, about GO 

 cells round. Calyptra small, delicate. Pistillidia about 12, 

 small. Capsule cylindrical-oblong. Spores purple, Androecia 

 spicate, perigonial bracts situated at the apex or middle of the 

 branches, or occupying the whole length, very rarely immediately 

 below the $ flowers, closely imbricate, ascending, similar to the 

 leaves, but broader at the base, which is swollen, sometimes v/ith 

 a third, small, antical tooth. Antheridia oval, single.
