lata, erecta, stricta, lineari- attenuata, subtus convexa sul- 
cata et glabra, supra striata villosula, margine denticulato 
aspera et longe ciliata, vaginis suis quadriuncialibus laxis 
basi dilatatis sulcatis glabris margine parce vel non ciliatis

$— 6 pollices longa, 33 lineas lata, supra glabra, pulcher- 
rime ciliata; in var. 7. pollices 21 longa, demum complicata 
et ob cilia margini adpressa ad speciem tota glabra. Ligula 
villosa. Caulina folia radicalibus similia, sed inde a quarto 
ab apice sursum longitudine decrescentia 8 — 1 - pollicaria, 
margine minus, vaginis vero circa oras distinctius ciliata, 
his etiam collo plus minusve barbatis; summum subulatum. 
Ligula eadem atque in inferioribus, Panicula in «. pedalis, 
in &. 8-pollicaris, in y. pollices 3 —32 longa, erecta, basi 
acuta, apice attenuata, hinc circumscriptione oblongo-lan-

vissimi, linea parum longiores, ramo subadpressi, flexuosi, 
glabri, basi nudiusculi, inferiores quadriflori, superiores 
wiflori, spiculis subsessilibus, alternis quidem, sed adeo 
approximatis, ut fasciculum fere forment spiculaeque multi-

hians, et tunc in multis spiculis truncata; superior istam 
valvulam aequans, paulo firmior, uninervis colorisque inten-

vis; superior isia paulo brevior atque tenerior, at latior, 
elliptico- ovata, obtusa, dorso plicato - canaliculata et secun-
