Vagina ssepissime apice fimbriate ligula semper prasente, nunc brevi, nunc longiorc et quandoque fim- 



briis ciliata.

Squamulce typice 3, interdum plurimae, abortu 2 vel nullse. 



Stamina 3-6 vel plurimae, filamentis basi liberis vel monadelphis. 



Styli plerumque ima basi conjunctly vix unquam indivisi, ssepissime 2— 3— 4-fidi. 



Caryopsis libera vel in sectione " Bacciferce n perigynio arete inclusa. 



Bambusacea, ob characteres supra enumerates, meo sensu, ab omnibus aliis graminum tribubus bene 



distinct se sunt. 



Genera Bambusacea in sectiones tres dividua sunt. 



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



Nees in Linn. ix. 466 (1831), et in Lindl. Nat Syst. et in FL Afr, Aust. 463, Bupr. /. c. Ill, 

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

 Culmus semper inermis, fistulosus, teres vel in f € Phyllostachy " semiteres, ssepissime fruticosus, vix 



arborescens, ssepe scandens, e nodis ramosissimus, interdum nanus, Tabasheer nunquam fundens : in 

 Platonia tantum lierbaceus enodosus. , Panicula in multis depauperata, simpliciter racemosa vel fere 

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

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

 Rettbergia, Chusquece) vel spatha vel bracteis perpaucis (e. g. Thamnocalamus et P hy Host achy s) quasi 

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

 in perpaucis (Arundinariis quibusdam et Thamnoc alamo) culmi floriferi et foliiferi discreti sunt. 

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

 imperfecta, Glumce ut plurimum paucinervise, interdum minimae vel obsolete, nunquam gemmiparre, 

 ssepe consistentia et colore flosculis perfectis aliense. Paha superior semper bicarinata. Stamina 

 3, basi libera, connectivo 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 conspicuo. 

 Gramma subseetionis primae, Arundin aria* , in liemisphserio utroque ; omnia alia hujus sectionis tantum in 



occidentali crescunt. 



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

 compressed and boat-shaped, to distinguish this section from true Bamboos, in which, he 

 says, the upper palea is depressed and broader at the back. I, however, do not find 

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

 palea of all the three sections. Link describes Triglossce as having 3 stamens, and 

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

 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), namelv
