to Chusquea, from which, as far as the structure and details of the spicula arc concernedj 

 it can scarcely he distinguished, althovigh in inflorescence and foliage the two genera are 

 widely apart ; and I have already, at pp. 52 and 53, stated in what respects these two 

 genera differ from all other grasses.

1. P. ELATA, Munro. " Panicula 13-14-pollicari, ramosissima, contracta, ramis fasciculatis 



approximatis, rhachi angulata hispido-scahra, glumis jparwis, subrotimdo-ovatls, acu- 

 minatis, foliis 9-10 lineas latis, vaginis hirtellis demum glabris." — Flatonia elata,

" Culmus erectus, 4-5-pedalis (Kunth), 12-18-pedalis (Bonpl.), simplex, teres, sulcato-striatus, glaber, 

 basi foliosus. Folia longissima, culmo parum breviora, lanceolato-lincaria, apice angustato-acutata, 

 plana, inferiora angustiora et canalieulata, cum vagina continua, striato-nervosa, nervo medio crasso 

 subtus prominente, coriacea, glabra, margine obsoletissime serrulato-scabra, 9-10 lineas lata. 

 Vagince sulcatae, hirtellse, tardius glabrae, ligula ovata, obtusa, glabra. Panicula elongata, 13-14- 

 pollicaris, ramosissima, contracta, ramis fasciculatis, approximatis, brevibus, adpressis, rliachique 

 angulata liispido-scabris ; spiculis vix 2 lin. longis, ovato-ellipticis, pedicellatis. Gluma parvae, sub- 

 rotundo-ovatte, acuminatae, fuscescentes, nitidulae, glabrse ; inferior brevier, subcarinata. Flosculi 

 neutri ovato-elliptici, acuti, obsolete triuervii, Iteves, glabri, flosculo fertili breviorcs. Palea inferior 

 (flosculi fertilis) coriacea, glabra, subrotundo-ovato-aeuta, obsolete nervosa, superiorem obsolete 

 binerviam, apice bilobam vix superans. Squamulce 3, subrotunda;, ciliata;, glabrte, inferne tnutti- 

 nervia. Styli 2, terminales, breves, recurvati, stigmatibus subplumosis. Ovarium (immatui'um) eybn- 

 draceo-oblongum, subarcuatum." — " Descrip. secundum specimen Humboldt." (Kunth.) . 



This plant, as represented by Kunth in his fine drawing, has very much the general 

 appearance of a large Eragrostis, and is extremely like P. acuminatissinui, which, how- 

 ever, is well distinguished by its long glumes.
