60 CLXXIII. GBAM1NE2E. (J. D. Hooker.) [Panicum. 



tichously spreading spikes. In t. 796 there are 10, all secund. The grain oft. Ill is 

 ovate-lanceolate, acuminate, with three dorsal lines; oft. 212 ovate-lanceolate, 

 acuminate; of t. 796 elliptic-oblong, acute. It is evident that in this as in other 

 cases, Eoxhurgh had not named his Icones in accordance with the descriptions prepared 

 for the " Flora Indica." 



P. SERICEUM. Soland. in Ait. Sort. Eew, 88, is a West Indian plant erroneously 

 entered as from " Ind. Or." by Steudel. 



P. SIMPLICISSIMUM, Koen. in Neue Schrift. Naturf. xxiii. (1788) 209 (ex Index 

 Kewensis). There is no such species described in the work cited, but Mr. Rendle 

 has pointed out to me that at the bottom of the page Koenig mentions a very 

 fine grass sent by him to Dr. Solander, adding, " Er hat eine Paniculam simpli- 

 cissimam." 



P. TENUE, Eoxb. Fl. Ind. i. 310 ; stem 1-6 ft. erect, ramous, panicle thin, spike- 

 lets binate on a common hairy pedicel with unequal partial pedicels, gl. Ill paleate, 

 grain ovate transversely waved. Wild in the Circar Mts. (Roxh.). Stem sometimes 

 prostrate and rooting. Leaves large, upper surface hairy, margins with very sharp 

 points ; sheaths shorter than the internodes, hairy, mouths bearded. Panicle erect, 

 till fruiting, then bowing as in P. miliaceum, of alternate compound nearly secund 

 racemes ; rachis 4-5-angled, branchlets 3-angled, flexuons hairy. Sp'ikelets smooth, 

 gls. many-nerved, III male in luxuriant plants. I have altered Eoxburgh's 

 phraseology to bring it into harmony with that of this work. I have seen no plant 

 answering to the above description except perhaps a small state of P. maximum. 



P. TRACHYPTTS, Trin. Panic. Gen. 170 ; rays subracemiform, shortly compound 

 from the base alternate, ray lets spreading, pedicels very short, spikelets lineal obovate 

 submucronulate pubescent, gl. 13-4 times shorter than the spikelet, 3-uerved, II 

 5-nerved, 4 mucronate rugose. Leaves glabrous lanceolate from a cordate base.

5. XCHNANTHUS, Swartz. 



'Annual or perennial branching grasses. Leaves broad. Spikelets 

 1-2-fld., long panicled, ovate or lanceolate, terete, articulate (but often per- 

 sistent) on their pedicels. Glumes 4, I II and III subequal or II longest, 

 strongly nerved ; III paleate or not, male or neuter ; IV much shortest, 

 stipitate, paleate, bisexual, oblong or oblong-lanceolate, stipes with 

 an anticous simple or 2-fid or 2 lateral appendages. Lodicules 2, minute. 

 Styles free, exserted apically. Stamens 3. Grain coriaceous, acute or 

 acuminate, polished, articulate at the base of the stipes. Species about 

 20, tropical. 



This genus differs from Panicum in the appendaged base of gl. IV. 



1. X. pallens, Munro in BentJi. Fl. Honglc. 414; stem slender elon- 

 gate, leaves broadly lanceolate, panicle open, rachis and subsecund 

 branches slender, gls. spreading, I ovate-lanceolate acuminate, III paleate 

 neuter or male, IV when mature exposed, turned on one side, oblong 

 obtuse, appendages 2 adnate to its sides. Thw. Enum. PI. Zeyl. 361 ;
