Culmus suffruticosus, crectus, subsolidus, intcniodiis l|-2-pollicaribus ; ramis paucis, ercctis, adpressis, 

 cito divisis in ramulos oligophyllos, (5-16 poll, longos, apicc spicigcros. Folia lanceolata vcl lineari- 

 lanceolata, 1-2^ poll, louga, l^-S liii. lata, basi obtusa, vix petiolata, apice loiigissime subulata, 

 margine serrata vel basin versus pilis longis fimbriata, subtus venulis transversis crebris conspicue 

 tessellata et ssepe pubescentia. VagiruB striatae, hirsutse, subconcolores, margine saepe longe fim- 

 briatie, ligula brcvi, hirsuta, obtusa, ciliata. Panicula spiciformis, vix basi interrupta, angusta, fusca, 

 4-6 poll, longa, rbacbi hirsuta, pedicellis brevissimis. Spiculce seepe monoiese, acutse, vix 3 lin. longae, 

 pubescentcs vcl hirsutse ; glumis brevibus, hirsutis, obtusis. Flosculi ueutri mueronati, dorso sca- 

 briusculo-liirsuti, conspicue nervosi, infe(juales ; longior hermaphroditum glabriorcm superaus vel 

 vix sequaus. Palea inferior mucronata, superiorem fcrc membranaceam involvens. 



This approaclies the preceding species, C. spicata, in many respects, but is at once 

 distinguished by the conspicuously tessellated leaves. M. Triana says it is called " Car- 

 risa " in Bogota. 



17. C. ABISTATA, Munro. Panicula elongata, apice fere spicata, ramis inferioribus com- 

 positis; glumis aristatis, longissimis, flosculos multo superantibus ; foliis lato-lanceo- 

 latis, subtus conspicue tessellatis.

" Cultni erecti, 5-6-pedale8, fruticeta impenetrabilia struentes." (Partem superiorem simplicem tantum 

 vidi.) Folia lato-lanceolata, 6-8 poll, longa, 9 lin. lata, glaberrima, basi vix attenuata, subito arti- 

 culata, apice acuta, margine coriaceo, subtus venulis transversis crebris elevatis conspicue tessellata. 

 Vagina glabrae, vel juniores hirsutae, ligula nulla. Panicula terminalis, 9 poU. longa, fere jubalis, 

 apice subspicata, radiis inferioribus sub 3-pollicaribus, compositis, subfalcatis, rliachi hirsuta, pedicellis 

 basi glandulosis, brevibus, spiculas vix aequantibus. Spicula ovata, (glumis exelusis) \ix 3 lin. longa, 

 subpTibescens. Glum<B 6 lin. longa, enerviie, basi latse, atteuuatse in aristam longissimam scabram. 

 Flosculi neutri subseqaales, acuminati, scabri, fere enervii, hermaphroditiim scabriusculum, apice 3-5- 

 nervosum aequantes. Squamula 3, basi callosae et multinervosae, apice lanceolatas enei'vosae. Stylus 

 cito bifidus, stigmatibus divaricatis et rocurvis. 



A very curious grass, resembling some species of Echinochloa in general appearance. 

 Jameson says, " It is a tall reedy grass, found only ou the Eastern chain of the Andes. At 

 13,000 feet it first makes its appearance, in irregular patches ; at 15,000 feet it com- 

 pletely covers the whole surface, forming what the natives call a ' carizal,' impenetrable 

 to man or beast. It continues upwards nearly to the limits of perpetual snow." 



18. C. Eendleri, Munro. Panicula elongata, angusta, longe exserta, composita, ramis 

 laxifloris adpressis, glumis obsoletis, ilosculis neutris paucinerviis ; foliis angustis, 

 subtus glabris.

 gati, l-l|-pedales, foliis 5-6, alii florifcri, bre\aores, foliis 1-2, ad nodos subtumidos fasciculati. 

 Interdum ramuli foliiferi abortivi, brevissimi, cito recurvi, spiniformes hunt. Folia in ramulis 

 foliiferis sub 4 poll, longa, in floriferis brevioribus saepe 1 poll, et ultra longa, 2—4 lin. lata, lineari- 

 lanceolata, basi attenuata, apice longe setaceo-acuminata, margine longe serrata, glabra, uer\is 

 secundariis 6-8 couspicuis. Vagina glabrje, margine stepe ciliatie, interdum nudic, ligula conspicua.
