COLONEL MUNRO'S MONOGRAT'II OF THE BAIMBUSACEtE. 11 



Fa^i»« saepissi me apice fimbriatu-, %«/« semper prrcseutc, nunc brevi, nunc longiorc ct (juan(lofjuc/(«(- 



briis eiliata. 

 " Inflorescentia: ])anicul:i perraro valdc composita, scepius contraetior ct depauperata, dcniqiic in (jui- 



busdam ad formam racemi aut spieic (in aliis verticillatffi in aliis siniplicis) (piin ad peduuculum mo- 



nostachyiim redacta " (Necs.) 

 Sfiicula multiflorte vel pauciflora; vel scsquiflonr, nunquam uniflonc. Nisi in subscctione " Arvndinarite " 



omnium flosculi infcriores 1 vel plurimi, abortivi, univalves, sscpc glumas refcrentes. Intcrdum 



quasi in Paniceis spiculae deorsum tantum, in plerisque quasi in Arundineii quibusdam sursura 



deorsumque, in subsectione " Arundinarice," quasi in Festuceis plerisque, sursum tantum imperfcct;e. 

 Palea inferior semper plurinervis, sviperior 2-6- plurinervis, carinata vel ecarinata, intcrdum (rarissime) 



deficiens. 

 SquamulcB typice 3, intcrdum pluriraffi, abortu 2 vel nulla;. 

 Stamina 3-6 ^el plurirase, filamentis basi liberis vel monadelphis. 

 Styli pleriimque ima basi conjuneti, vix unquam indivisi, sfepissime 2-3-4-fidi. 

 Caryopsis libera vel in sectione " Baccifera " perigynio arete inclusa. 

 BambusacecE, ob eharacteres supra enumerates, meo sensu, ab omnibus aliis graminum tribubus bene 



distiuctse sunt. 



Genera Bambusacea in seetiones tres dividua sunt. 



1. Trigloss^, Link, in Hort. Berol. i. 248 (1827) ; Nees in Agros. Bras. 520 (1829). Anindinaria, 

 Nees in Linn. ix. 466 (1834), et in Lindl. Nat. Syst. et iu Fl. Afr. Aust. 463, Rupr. I. c. Ill, 

 Steud. Syn. 331, jNIiquel. /. c. 361. 



Culmus semper inermis, fistulosus, teres vel in " Phyllostachy " semiteres, sjepissime fruticosus, vix 

 arboreseens, ssepe scandens, e nodis ramosissimus, interdum nanus, Tabasheer nunquam fundens : iu 

 Platonia tantum herbaceus enodosus. Panicula in multis depauperata, simplieiter racemosa vel fere 

 spicata, etiamve subrotunda capitulum referens, in aliis tlijTsoidea decomposita, amplissima effusa- 

 que ; saepissime basi nuda, interdum vagina folii terminalis (e. g. Merostachys) vel foliis ipsis (in sect. 

 Rettbergia, Chiisquece) vel spatha vel bracteis perpaucis (e. g. Thamnocalanms et PhyUustachys) quasi 

 involucrata : in plurimis terminalis i. e. ex apice ramorum vel ramulorum foliiferorum egrediens ; 

 in perpaucis [Arundinariis quibusdam et Thamnocalamo) culmi floriferi et foliiferi discreti sunt. 

 Spicula pluriflora vel raro sesquiflora, in subsectione prima sursum, iu aliis vel deorsum vel utriuque 

 imperfecta. Gluma ut plurimum paucinervise, interdum minimae vel obsolete, nunquam gemmiparse, 

 ssepe consistentia et colore floseulis perfectis aUense. Palea superior semper bicarinata. Stamina 

 3, basi libera, conneetivo nunquam elongato. Squamulse 3 semper adsunt. Stylus, plerumque 

 cito, supra basin 2-3-partitus. Caryopsis ovalis oblonga aut lineari-oblonga, sulco laterali notata, 

 scutello extus eonspicuo. 



Gramina subsectionis primae, Arundinaria , in liemispliDerio utroque ; omnia alia hujus sectionis tantum in 

 oecidentali crescunt. 



Nees has principally trusted to the form of the upper palea, which he describes as 

 compressed and boat-shaped, to disting-uish this section from true Bamboos, iu Avhich, he 

 says, the upper palea is depressed and broader at the back. I, howcAer, do not lind 

 this distinction of sufficient value, as both forms are found indiscriminately in the upper 

 palea of all the three sections. Link describes Trif/lossce as having- 3 stamens, and 

 spiculae with 1 or 2 bracts at the base, and thus distinguished from Bracteijlorce, 

 which have 6 stamens and several bracts. Grisebach, at p. 529 of the ' Flora of the 

 British West-India Islands,' includes 3 genera of this section (Triglossce), namely
