wliich genus I should have heen inclinod to iiaclude them had they hocn dwellers in the 

 East instead of the West. 



GuADUA PARVIFLORA, Pi'esl in E,cliq. Useiik. =Arthrost!/lidiiim maculatum, Rupr.

Schreber, (len. Plan. no. G07 (1789); Roxburgh (179.5). Armidurbor, Cusp. Bauliiu (1671); Ruinijli. 

 Herb. Amboin. iv. 5 (17uO). Ann) do, sp., Tjinn. ct Lour. Buvibos, Retz. Obs. v. 24' (1789) ; Pers. 

 Syn. (1805). 



Spicula multiflora vel rare paucittora, si/rsum deorsuinque imperfecta, vcl cylindi-ica, elongata, rhachilla 

 plus minus conspicua, vel ovata aut oblonga, rhauliilla abscondita, interdum fere obsoleta, plenimquc 

 sessilis, raro glumis distantibus, quasi pedicellata. GIuiikb dufc aut numero indefinite, iuferiores 

 plerumque gemmiparfe et breves, superiores paleis inferioribus flosculorum similes et pro flosculis 

 habendie, sfepe plurinervcs. Palea inferior plurinervis, mutica aut mucronata, plerumque glabra 

 coriaceo-chartacea ; superior membranacea, angustior, vel subsequilonga vel longior, bicarinata 

 cai'inis non alatis sed ssepe conspicue fimbriatis. Squamulce typice 3, plerumque obtusie, ciliat'cc, 

 membranaeese, raro abortu 1-2 deficientes. Stamina 6, basi libera, antheris vel obtusis vel apiculatis 

 vel apice peniciUatis. Stylus in sectione prima brevis, cito et ssepe fere ad basin S-Jidu.s, in 

 secunda ad basin subbulbosus, non tam profunde 2-3-fidus, in tertia longus, basi simplex, super ne 

 taniuin in stigmata 2-3 secedens. Stigmata vel brevia plumosp,, vel longa et pilosa. Ovarium vel 

 obovatum, apice hirsutum, vel lineari-oblongum, vel rostratum. Caryojjsis oblonga vel lineari-ob- 

 longa, obtusa aut acuta, sulco longitudinali conspicue notata, palea supcriorc plerumque arete inclusa. 



Oramiua arborescentia, vel pauca suffruticosa, interdum seandentia. Species unica [B. vulgaris) cosmopo- 

 litana, reliquse omnes orbis antiqui orientalis incolffi. Culmus saepe altissimus, usque ad 120-pedalis, e 

 nodis ramos saepe ramosissimos emittens, interdum spinosus, ramis juuioribus saepe pungentibus. 

 Folia varia, angusta vel lata, venulis transversis vel nidlis vel conspicuis, vagiuis plerumque ore fim- 

 briatis. Inflorescentia vel " scapus radicalis," vel panicula, in culmo inferne foliis denudato, interdum 

 ramosissima et quam maxime decomposita, ramis simpliciter vel composite spicatis, saepe laxiusculis, 

 adjectis interdum ramulis foliiferis quorum folia minora sunt reliquis, spiculis ssepissime semi- 

 verticillato-spicatis. In B. nana et paucis aliis, panicula saepe in ramulis (basi foliatis) teraiinalis, 

 fere simplex et interdum valde depauperata. 



I have already, at p. 76, mentioned how very little Bambusa differs as a genus from 

 Guadtia. I have not included any species in Bambusa in which the filaments are mona- 

 delphous, but have placed them in one or other of the two following genera. It appears 

 to me that the united filamental tube of these two genera indicates an interesting transi- 

 tion between the true Bamboos and the berry -bearing ones, in which the peculiar envelope 

 enclosing the real fruit, which I have already referred to at page 4, may possil)ly prove 

 to be an interior staminodium, or series of stamens of which the tube only is perfected. 

 This envelope, in its youngest state, is very soft and impressive ; for I have often ol)- 

 served it bear the impression of the vascular bundles of the true filaments. 



Conspectus Specierum. 



Sect. I. Stylus breWs, cito fere ad basin 3-fidus, vel (in B. balcooa) ad vel paulo infra medium 3-lidus, 

 stigmatibus plerumque brcvibus, phimosis. 

 Culmus inermis. Ovarium obovatum. Spicula cylindrica, elongata. 

 Folia plerumque angusta et subtus discoloria, venulis transversis nnllis.
