Folia angusta; lincari-lanpcolata, acuta, viridi-glauccscciitia, 1-2 poll, longa, 1-3 lin. lata, basi sub- 

 attenuata in iJctiolum flavescentcra pilosum vel glabrum, supra glabra, vel uno latere pubcsccntia, 

 subtus scabra [Steud.) vel, prajcipuc basin versus, plus minus pubescentia, nervis secundariis incon- 

 spicuis. VagincB pubcsccntes vel subglabrae, apice parce fimbriatae. Racemus simplex, sccundus, 

 arcuatus, terminalis, vix 2 poll, longus, rhachi hirsuta, spiculis pluribus scssilibus fere imbricatis. 

 Spicula pubescens, linearis, 2-4-5-flora; flosculo infimo 1-paleaeeo, neutro, palea ovata subito mu- 

 cronata, reliquis breviore. Gluma 2, lineares, distantes, mucronato-acutissunse, dorso pubcsccntes. 

 Palea inferior (flosculi fertilis) pubescens, acuminata, nervosa. Genitalia evoluta nunquam vidi. 



I liave never had an opportunity of examining a perfect spicula of this plant ; but I 

 believe that it is generally 3-flovvered, with only 1 (the intermediate one) fertile. Fen- 

 dler's Plant has no flowers, and the leaves are more glabrous than in the Mexican spe- 

 cimens, but I believe it to be the same. Fendler says it is found only in the highest 

 mountains of Venezuela. This species is very closely allied to the following : —

Culmus valde inanis, ramulis innumeris, fiUformibus, tenuibus, erecto-patulis, subsimplicibus, pedalibus, 

 apice fioriferis, inferne foliosis, ad nodes fasciculatis. Folia angusta, lineari-lanceolata, acuta, 

 glaueescentia, lg-2g poll, longa, 2-3 lin. lata, basi parum attenuata in petiolum hirsutum, margine 

 aspera, supra glabra, subtus (basin versus tantum) pubescentia, costa ner\'isque secundaidis (in tota 

 lamina sub 7) subobsolctis. Vagina inter nervos prominulos tcnuissime undulato-scabrae, superne 

 margine ciliato-scabrse, efimhriata (fimbriatae fide Rupr.) brevibgulatae. Racemus simplex, termi- 

 nalis, siibpollicaris, spiculis sub 8, approximatis, sessilibus. Spicula pallide straminca, 5 lin. longa, 

 subcylintb'ica, glabra, 3-6-flora, flosculo infimo subulato neutro, i)alea acuminata 5-nervia, rbachillae 

 articulis brevibus. Gluma inferior linearis, apice scabra ; superior longior, 3-nervis, apice acuminata. 

 Palea inferior (flosculi fertilis) 7-nervis, attenuata, apice scabro, nervosa, dorso glabra, margine su- 

 perne tcnuissime ciliata; superior subobtusa, longior. Squamulce 3, insequales, duae majores, apice 

 attenuatse et fimbriatae. Stylum et ovarium nunquam \ddi. 



Steudel and Ruprecht both state that it is probable that Chusquea? lejitophyllu, Nees 

 in Linn. ix. 489, may be the same as A. Trinii \ but I think the size of the leaves alone 

 keeps it distinct. Ruprecht describes this plant as having "vaginae fimbriatae;" but 

 that is certainly not the case in Claussen' s specimens, which I have seen. This species 

 is evidently very closely allied to the preceding, A. racemijlorum, and is princii^ally dis- 

 tinguished by the glabrous spiculse, of rather different structure, and leaves with decided 

 ligules and no fringe to the vaginae. Rujirecht's drawing is evidently made from an 

 abnormal spicula, as, in the analysis, one stamen is represented as becoming converted 

 into a style.
