 canaliculatum, Gaud., Freyc, Voy. Ur. Phys., Bot., I, 287. 



Shoots ascending from a more or less creeping base, to 60 cm. long, 

 the lower part simple, unequally quadrangular, deeply grooved, 5-stelical, 

 asperous, the upper part branched; pinnae unequal, irregularly spreading, 

 simply pinnate; pinnulae irregularly parallel, 3 — 3 'A mm. broad including 

 the lateral leaves, narrowed towards the apex. Leaves rigid ; of the stem 

 regularly arranged, approximate, ovate-acuminate, straight, soon hetero- 

 morphous, falcate, erected; of the branches heteromorphous; leaves of the 

 lower plane spreading; of the branchlets close, falcate, ovate-oblong, 2 — 2 'A 

 mm. long, 1 — VU mm. broad, acuminate, entire, with the upper base rounded, 

 the lower base truncate-rotundate to truncate-cordate ; leaves of the upper 

 plane erect; of the branchlets, oblong, 'A — 'A as long, parallel or incurvate- 

 falcate, acuminate, entire, obliquely rounded at the base, or the outer 

 base rotundate-cordate, the inner base rotundate-cuneate. Spikes

Shoots erect from a creeping or ascending base, the lower part simple, 

 obtusely 3-angular, rather subterete, irregularly sulcate when dry, smooth, 

 glossy, dirty-stramineous, to 3 mm. thick, 5 — 7-steUcal, sparingly foliate, 

 the upper part branched, densely foliate; pinnae articulated at the base, 

 copiously pinnate, linear-lanceolate, to 20 cm. long; pinnulae approximate, 

 hardly more than 2 'A cm. long, the lower often forked; ultimate branch- 

 lets 5 mm. broad including the lateral leaves. Leaves of the branches 

 conspicuously heteromorphous, those of the branchlets rather the largest; 

 of the lower plane falcate-oblong, narrowed at the apex but blunt at the 

 point, somewhat unequal-sided, entire, obsoletely pellucid-margined on the 

 upper side by a single row of sclerotic cells, cuneate and revoluto- 

 auriculate at the upper base, truncate and rotundate-subauriculate at the 

 lower base, with the midrib thickened gradually towards the upper ';s, 

 the largest leaves S% mm. long and TA mm. broad; of the upper plane 

 falcate-ovate, nearly equal-sided, shortly acuminated into an oRtuse mucro, 

 entire, finely pellucid-dotted, narrowly pellucid-margined by a single row 

 of sclerotic cells, decurrent with an adnate auricle on the outer side at 

 the base, subtruncate-rotundate at the inner base, the largest leaves I'A 

 mm. long and 'A mm. broad.
