I have never had an opportunity of examining a perfect spirilla of this plant; hut I 

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

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

 cimens, hut I helieve it to he 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, filiformibus, tcnuibus, erecto-patulis, subsimplicibus, pcclalibus, 



apice floriferis, inferne foliosis, ad nodos fasciculatis. Folia angusta, lincari-lanceolata, acuta, 

 glaucescentia, 1|-2| poll, louga, 2-3 lin. lata, basi parum attcnuata in petiolum hirsutum, margine 

 aspera, supra glabra, subtus (basin versus tantum) pubescentia, costa nervisque secundariis (in tota 

 lamina sub 7) subobsoletis. Vagina inter ncrvos prominulos tenuissime undulato-scabraj, superne 

 margine ciliato-scabrse, efimbriata (fimbriate fide Rupr.) breviligulatse. Racemus simplex, termi- 

 nals, subpollicaris, spiculis sub 8, approximatis, sessilibus. Spicula pallide straminea, 5 lin. longa, 

 subcylindrica, glabra, 3-6-flora, flosculo infimo subulato neutro, palea acuminata 5-nervia, rhachill tt 

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

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

 perne tenuissime ciliata; superior subobtusa, longior. Sguamula 3, inscquales, due majorat, apice 

 attenuate et fimbriate. Stylum et ovarium nunquam vidi. 



Steudel and Ruprecht both state that it is probable that Chusquea? leptophylla, 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 fimbriate ; " 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 principally dis- 

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

 ligules and no fringe to the vaginas. Ruprecht's drawing is evidently made from an 

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



into a style.
