(26) Ij. rupicoluni, r. A. r. n., Bull. Btz., 1914, XVI, 39. 



Shoots probably erect or nutant, about 25—50 cm. long, 2—3 times 

 dichotomously branched, the central branches 2 — 2Vs cm. diam. including 

 the leaves. Leaves crowded, 8-farious, horizontal or spreading, or the 

 lower deflexed, rigidly coriaceous, acerose, lanceolate-subulate, 12Vj mm. 

 long, 2 mm. broad above the base, entire, acute, the edge somewhat 

 revolute, the base slightly rotundate-cuneate, decurrent, the decurrent 

 portion often 2-costate when dry. Spikes solitary or double, simple or 

 forked, the branches 5 — 6 mm. diam.; sporophylla spreading, triangular- 

 ovate, subulate-acuminate, 3 — 4 mm. long, the lower a little longer. — 

 Readily distinguished from L. squarrosum Forst. by its proportionally 

 shorter and broader, spreading sporophylla.
