lax, older ones purplish ; ligule membranous, truncate ; the 

 single cauline leaf has a narrow closely appressed sheath about 

 equal to the blade which reaches the base of the cylindrical spike ; 

 spikelets small, in a densely crowded panicle, ovate or ovate- 

 lanceolate, acute ; glume I. H of gl. III., broadly ovate, blunt with 

 sheathing membranous edges and 3 well-marked pui-ple veins ; 

 gl. II. longer than gl. III., oval with an abruptly acute apex 

 and 5 broad purjjle veins ; gl. III. very broadly oval, acute, 

 5-veined, enclosing a small barren pale ; fertile glume about }, 

 gl. II., oval, smooth. 



Leaves \}r to 2i^' in. long, blade not exceeding }r line broad, 

 tapering to a point ; inflorescence 10 to 15 lines long; spikelets 

 ^ line long. Glume I. .V line long, gl. II. |^ line, gl. III. t line,, 

 fertile gl. less than I line. 



Has somewhat the appearance of a small form of P. mi/osnroides^ 

 but is distinguished by the large first glume of the spikelet and 

 the acute second and third glumes.

25. P. catumbense Eendle sp. nov. 



Shoots slender, erect, annual (9 to 12 in.), rising from a 

 perennial woody rhizome from the lower side of which spring- 

 numerous wiry roots ; basal leaves short, membranous, sheathing : 

 upper ascending, sheaths nan^ow, terete, closely striate, sparsely 

 pilose, ligule very short, truncate, pilose, blade very narrowly 

 linear-lanceolate, acuminate; inflorescence short (1,V in.), dense, 

 interrupted, strict, linear or linear-oblong ; spikelets laterally 

 compressed, ovate-lanceolate to oval, glabrous, 2 lines long ; gl. I. 

 ovate, acute, 7-nerved, H length of spikelet; gls. TI. and III. equal, 

 strongly nerved, 2 lines long, the second cymbiform, acuminate,, 

 the third convex, ovate, acute, subtending a short narrow pale and a 

 ^ flower ; fertile gl. ^ length of two lower ones, broadly ovate, acute. 



The short woody nodulose rhizome 1 to 2 lines thick, bears a 

 few crowded yQung shoots and the charred bases of older ones. 

 Leaf-sheaths closely enveloping and generally exceeding the very 

 slender internodes, 2 to 4 in. long ; nodes glabrous. Leaf -blades 

 almost erect, 1^ to 2!", in. long, a little more or a little less than 

 1 line broad, sparsely pilose on the upper face, the midrib and 

 sometimes the lateral v( ins, protruding on the lower. Glume I. 

 convex, 1 1 line long, 2 outermost nerves short ; gl. II. when 

 flattened ovate from a broad truncate base, 9-nerved, barely 2 lines 

 long, gl. III. similar but slightly broader, pale, slender, thin, 

 lanceolate, 1 line long, anthers of flower ^ line long. Fertile gl. 

 subcoriaceous, inconspicuously .3-nerved, 1] line long, pale of equal 

 length, anthers of $ flower 1] line long (ovary still very small). 



Approaches some large-flowered forms of P. indicicm, but easily 

 distinguished by its habit, interi'upted spike, and acute glumes.
