Culmus arboreus, excelsus, 50-70-pedalis, cavus, inermis. Folia lanceolata, basi subcordata vel attenuata, 

 petiolata, petiolo supra subhirsuto et saepe transverse ruguloso, margine hispida et interdum basin 

 versus longe ciliata, utrinque viridia vel raro glaucescentia, 6-12 poll, longa, 1-2 poll, lata, supra 

 tactu scabra, subtus pilis breribus, demum deciduis liLrsuta, ner^ns secundariis utroque latere 7-11, 

 venulis transversis distantibus, plus minus conspicuis. Folia inflorcsccntiam iutrantia multo minora 

 sunt. Vagina striatae, setis diaphanis, dein deciduis hirsutje, apice truncatje, ore plerumque nudae 

 vel pUis paucis ciliatae, ligula producta, obtusa, ciliata vel glabra. Inflorescentia "scapus radicalis, 

 spicis verticillatis, verticillis interdum proliferis" (teste Roxburgh) ; interdum panicula composita, 

 internodiis subteretibus, apice hirsutiusculis, ramis ad nodos paucis, 2-3, simpUcibus vel raro com- 

 positis, 6-18 poll, longis, internodiis uno latere sulcatis et hirsutis, spiculis plerumque subdense 

 glomeratis in verticillos, vel approximatos, vel 1-2^ poll, a scipsis invicem remotos; interdum {e.g. in 

 spec, e C. B. S. in herb. Hook.) panicula infeme ramosa, ramis inferioribus et spicigcris ct foliiferis 

 ad eundem nodum, superne subverticillato-spicata, verticillis densis, globosis, ramulos 1-2 breves 

 interdum emittentibus. (Hjcc forma B. capemis, Rupr. est.) Spicula 4-6 lin. longa, ovata, mollis,

 rhachilla abscondita. Palea inferior nervosa, membranacea, ovata, mucronata, margine superne 

 fimbriata, (laevis, Roxburgh), pallide straminea vel demum fiiscescens, inflata; superior vix brevior 

 sed angustior, inter carinas nervis 4 anastomosantibus percursa, carinis et margine hispido-cUiata. 

 SquamuUe 3, variabiles, plerumque ovales, membranaceae, longe ciliatae, inaequales, duse obtusissimae, 

 tertia longior, sublanceolata. Anthera seta cito caduca apiculatae. Stylus hirsutus, ad vel paulo 

 infra medium in stigmata 3 sublonga, flexuosa, hirsuta divisus. Ovarium fimmaturum) rostro hir- 

 suto, in stylum attenuatum. 



In numerous respects, especially in the form of the spicula, this species very closely 

 approaches B. Beecheyana and B. Oldhatni ; but the much thicker and more deeply trifid 

 styles have induced me to place it in the first section of the genus. Roxburgh, whose 

 drawing represents apparently a young undeveloped flowering culm, states that lie never 

 saw this species but once in flower : and dowering specimens must still be very rare ; for 

 I have never seen anything like a perfect one ; and most of those which I have quoted
