nitidse, superne sulcato-striatae et pilis brevibus canescentibus subhirsutae, demum glabrae, infra 

 petiolum membrana chartacea terminate, ore ciliis pallidis fimbriate. Panicula dioica, rhacbi bre- 

 vissima, fere nulla; spiculis 5-8-10, insequalibus, glomeratis, 1-2 erectis, reliquis pendentibus, vix 

 e vagina suprema exserta et folio superata, Spicula (mascula tantum visa) 1-2 poll, longa, nervoso- 

 costata, 7-10-ftora, flosculis 2-3 inferioribus unipaleaceis, neutris, sequentibus 3-4 bipaleaceis, mas- 

 eulis, 2-3 terminalibus gradatim tabescentibus, rhachillae articulis brevissimis. Gluma 2, breves, 

 mucronatse. Flosculi neutri lati, nervis 16 validis notati, subobtusi, breviter mucronati. Palea 

 inferior (flosculi masculi) neutris simillima sed longior, 7-9 lin. longa, mucrone interdum incurvo ; 

 superior multo brevior, multinervia, lata, bicarinata, carinis late alatis et superne longe ciliatis. 

 Stamina 6, filamentis brevibus. Squamulce 2-3 in flosculis masculis, ovatse, obtusse, inultinervosae. 

 Styli rudimenta nulla. 



Spruce, in his notes, mentions having sent male and female specimens ; but all the 

 spiculse I have examined contain male flowers only. In foliage this approaches very 

 closely to G. latifolia; but the spiculse are very different, and in this latter respect it 

 approaches G. amplexifolia, from which, however, it is well distinguished by having very 

 simple instead of compound inflorescence.

This species has narrow leaves, very similar to those of G. wujudifolia ; but the spicula' 

 (sometimes very hirsute, but always more or less so) distinguish it at once from all other 



Sta/ui 



spee.es with large spicule. The squamute are different from those of all other specie,
