(49) E<. scariosuni, Fofst., Spring, Mon., 1, 108; Bk., Fern All., 29. 

 Main stem wide-trailing or ascending; branches ascending, irregularly 



dichotomous, reaching a length of 15 — 30 cm.; branchlets flattened, dorsi- 

 ventral, 3— 4V2 mm. broad including the lateral leaves. Leaves rigidly 

 coriaceous; those of the main stem isomorphous, scattered, erected, adpressed, 

 sublanceolate, at length scariose at the apex; leaves of the branchlets 

 heteromorphous, placed in 2 parallel planes; lateral leaves (of the lower plane) 

 laxly placed in 2 opposite rows, arcuate-ascending, lanceolate, 3 — 4V2 mm. 

 long, entire, acute, keeled, distinctly decurrent; intermedial leaves (of the 

 upper plane) closely placed in 2 close rows, erect, adpressed, sublinear- 

 oblong or sublanceolate, very small, entire, often scariose at the apex. 

 Spikes single or rarely double, 2'/2 — 5 cm. long, cylindrical, thick, sessile 

 or stalked at the end of the branchlets, often several to many to a branch, 

 the stalks provided with remote, subulate, minute bracts; sporophylla 

 broadly ovate, apiculate, the apex and margin finally lacerato-scariose.

Main stem wide-scandent, vriry, stramineous, copiously branched, 

 bearing radially arranged, uniform, ascending, subulate leaves ca 3 — 5 

 mm. long; barren branches flattened, dorsiventral, erecto-patent, compound, 

 the ultimate branchlets divaricating, 5 — 10 cm. long. Leaves of the 

 branches heteromorphous, pale-green, thin but firm, placed in 3 parallel rows; 

 lateral leaves (of the central plane) arcuate-ascending, 3 — 6 mm. long, 

 acute, entire, with a decurrent base 2 mm. broad ; dorsal leaves (of the 

 upper plane) smaller, linear, acute, approximate, adpressed, in 2 close planes; 

 ventral leaves (of the lower plane) very small, spine-like, distant, placed 

 in 1 row. Spikes very abundant, pendulous or nutant, cylindrical, 1 V2 — TVj 

 cm. long, terminal and lateral on copiously branched, bracted peduncles 

 forming panicles apart from the barren branches; sporophylla ascending, 

 imbricated, broadly ovate, small, acuminate, toothed below the cusp.
