26 COLONEL MUNRO'S MONOGRAPH OF THE HAMBUSACE^.

 brevibus. Stylus cito bifidus in stif^raata 2 brevi-plumosa. Ovarium (inimaturum) in styhim attenuatum. 



In many respects, especially the heterogeneous spicula; and the vanishing of the midrib 

 of the leaves above the middle, this species approaches Arthrostijlidium maculutum, 

 ilupt., affording another indication of the proximity of the two genera. However, the 

 vi'ry long cilia to the vagina) and short ligulu; at once distinguish this from Ruprecht's 

 plant. M. Triana's specimens contain very few perfect spicukc.

The specimens which I have seen of this species contain each a panicle with 1 or 2 

 leaves, and therefore give no information as to the habit of the plant. Gardner says 

 that it grows 6 feet high, and is found in the virgin forest and iu moist rocky places. 

 Ruprecht describes and figures the style as trifid, and the squamulae quite smooth ; l)ut 

 iu the specimens which I have examined, including oue from Sellow, the style is decidedly 

 bilid, and the squamulae are much fringed.
