COLONEL MUNRO'S MONOGRAPH OF THE BAMBUSACE.E. 51 



5-nervis, carinatus, in sul)\ilam longara scabram abruptc acuminatus ; sccundus similis, set! longior ct 

 7-iiei'vis. Palea inferior (fiosculi fertilis) 17-19-nervis, apicc longc rostrato-acuminata, plerumque 

 dorso subglabra, scd semper ad margiues pilis fuscis hirsuta ; superior sublongior, bicarinata, carinis 

 ciHatis vel hirsutis, utroque latere 4-nervia, apice plus minus conspicuc bifida. Flos tcrminalis 

 ]-paleaceus, magis evolutus quam in reliquis speciebus, pediccllo brcvi. Squamula ^,\ax\cto\&t<R, 

 superne fimbriatse, infequalcs, duoe latiores, fere encrvosEe. Stylus basi simplex, stigmatibus superne 

 divergentibus. Ovarium immaturum. 

 The details of the structure of this curious species are remarkably well represented in 

 Sir William Hooker's drawing above quoted, although I do not find the squamulse united 

 at the base as there shown. There are occasionally some abortive spiculae mixed with 

 the others ; and sometimes, indeed often, both palese of the fertile floret have green her- 

 baceous points, which in the upper palea are sometimes remarkably divergent ; and in 

 those cases it is considerably longer than the lower palea. Gardner says this grass is 

 common in low woods about Rio, rising to a considerable height, climbing among and 

 supporting itself on the branches of shrubs amongst which it grows. I have but little 

 doubt that this is Steudel's Chusquea fimbriata, which, at any rate, is certainly not a 

 Chusquea, in consequence of the terminal incomplete flower. 



Duse sequentes, tantum absque floribus notse, segre discernendse sunt. 



9. M. Sellovii, Munro. " Culmo primario exasperate, vaginis ore herbaceo-barbatis, 



foliis glaucescentibus serrulato-scaberrimis." — Nees, Agr. Bras. 531, adnot. iii. ; 



Rupr. I. c. 127, adnot. 

 Hab. Paraguay in acumine montis Cabo do Butucai-ay, Sallow, s. v. Nees. 



The herbaceous beard to the vaginae, which, I confess, is a term I do not quite under- 

 stand, appears to keep this distinct from other species, although Nees considered it might 

 be a young state of one of the three he has described. 



10. M. BuRCHELLii, Munro. Foliis lineari-lanceolatis, l-3-5| poll, longis, 7-9 lin. latis, 



supra glabris, subtus glaucescentibus, glaberrimis sed punctulis minutissimis tactu 

 subasperis, vaginis glabris, superne uno latere oreque fibris pallidis longis fim- 

 briatis. 



Hab. in Brasilia australi, pr. Santos ("Taquarra vel Taquarri miri" incolis), no. 3243 ! Burchell. v. s. 



" Culmus solidus vel farctus (maturus eavus est) , gracilis, 30-40-pedalis, apieem versus flagelliformis, pen- 

 dulus, non ramosus sed verticillatim ramulosus" (Burcliell), interuodiis supremis fibformibus, vix 

 I lin. diametro, pilis rcversis per totam longitudinem asperrimis. Rami vel ramuli (fide Burchcll, 

 10-12) foliiferi tantum visi, basi strigoso-hirsuti et bracteis imbricati, apicc 4-foliati, 6-9 poll, longi, 

 diametro culmum superantes, ad uodum quemque semiverticillati. Folia (ramorum) infima poUicaria 

 ovato-lanceolata, superiora lineari-lanceolata, fere setaeeo- acuminata, basi attenuata in petiolum 

 brevem nigrescentem, margine aspera, supra glabra sed nervis 2-3, margine uno setulis bre-\-issimis 

 subasperis, subtus glaucesccntia, glaberrima, punctulis minutissimis vix tactu aspera, nervis 

 secundariis utroque latere 7. Vagina subglabrse, superne uno margine oreque fibris pallidis longis, 

 sajpc subcirrhosis, fimbriatae. 

 The internodes which I have seen of this species are extremely rough to the touch,
