long, green, inclining to pale-green at tips of branches ; branches 

 bi-pinnate throughout, very close set and overlapping. Leaves : 

 lateral, distichous, spreading, imbricate, ovate, acute, slightly 

 and distantly serrate at tips, margined ; nerve very stout and 

 broad at base and extending beyond middle ; cells rhomboidal, 

 larger at base ; the dorsal leaves broadly orbicular, apiculate, 

 margined ; margins entire, slightly uneven ; nerve vanishing 

 beyond middle ; cells oblong, small at tip and margins, larger 

 at centre and base ; stem leaves similar to dorsal ; perich^tial 

 narrow oblong-lanceolate, very acuminate, entire ; cells narrov? 

 oblong rectangular. Fruit- stalk : 8-9 on one plant, each singly 

 arising from the base of a branch on the main stem, or from a 

 fork of the primary branches, slender, erect, red, 6 lines high, 

 shorter than frond ; base very filiform, vaginaut ; vagina large, 

 cylindrical, dark-brown. Capsule sub-erect and horizontal, 

 about 1 line long, oblong, reddish, smooth, slightly rugose at 

 base ; outer teeth dark-brown, subulate, with a dark median 

 line, very closely transverse-sulcate, edges much roughened 

 (sub-denticulate) with numerous dark teeth, greatly acuminate, 

 tips flexuous, curved; inner teeth just as long as outer, pale, 

 remotely barred with a median line, acuminate, bifid for one- 

 third of length from tip, with three filiform jointed cilijB, shorter 

 than teeth, alternate between them.

 pressed, hairy, J^ inch wide. Leaves small, f line, sexfariously 

 disposed, obovatc-oblong, very obtuse, slightly narrowed at base, 

 imbricate, very thin, glossy, of a pleasing bright-green (lighter 

 in age), wavy, tips recurved, margin entire, thickened, and (with 

 nerve) red in age ; nerve extending ^ ol leaf, diverging near tip 

 with a very short branch at divergence, stout at base, fine at 

 top ; cells orbicular, small, particularly at apex and sides, 

 larger and oblong at lower centre and base ; pcrichjetial leaves
