CXII. GEAMINEiE 



[Melocalamus 



thick coriaceous, shorter than internodes, blade linear-lanceolatej recurved. 

 L. 9-12 by 1-2 in,, pet. \ in., n. 20-30 on J in. M. frequently, panicle large^ 

 often leafy, branches iistulose, bearing half -whorls of long hairy spikes, with 

 globose compact fl. heads J in. diam., like the beads of a rosary, |-2 in. apart, 

 Spikelets small, | in. long and as broad, fertile ii. 2, lodicules large, ciliate, 

 ovary glabrous, style short, stigmas 2 or 3. Er. 1-1 1 in. diam., the pericarp 

 fleshy while immature, ultimately coriaceous, the embryo has a large scutellum 

 without endosperm. The seed often germinates while attached to the branch, 

 putting forth a shoot and tuft of roots before falling to the ground.

Spikelets usually 2-5 on an arrested axis, so as to appear fascicled, in the 

 axils of large bracts, each spikelet with numerous empty glumes and one fl., 

 rarely bisexual, usually ^ with a rudimentary pistil or $ with sterile 

 anthers. In the axils of the lower empty glumes, or rather bracts, are 

 frequently buds which develop into short branchlets with a spikelet at the 

 end. The fascicles of spikelets are on unilateral spikes, which are 1-6 in. 

 long and are arranged in long narrow pedunculate more or less unilateral 

 panicles. The peduncle of these panicles consists of several often elongated 

 internodes, at the nodes with sheathing bracts, rarely with well -developed 

 L The panicles are of unequal length (the longest up to 3 ft.) and stand in 

 dense lateral fascicles at the nodes of the culm. Most of these panicles are 

 androdynamous, that is predominantly or exclusively male, while others, 

 chiefly the shorter panicles, are gynodynamous, that is, predominantly or 



exclusively female, bisexual 

 fl. occurring occasionally in 

 either. In some cases the 

 spikelet is 2-fld., and the 

 palea of the lower fl. has one 

 or two pairs of nerves. Fr. 

 large, pyriform, beaked, the 

 cells of the thick fleshy peri- 

 carp filled with starch. Seed 

 when ripe, without endo- 

 sperm, the embryo with a 

 large scutellum, which is 

 separated from the pericarp 

 by a thin layer of thin-walled 

 more or less crushed cells. 

 When the seed gei-mi nates 

 the embryo derives its first 

 nourishment from the starch 

 of the pericarp. (This descrip- 

 tion relates to 31. bam- 

 biisoideSj fl. and fr. of the 

 other species not being 

 known.)
