 5-7-flora, glumis 2, brcvibus, muticis, nunquam gemmiparis ; flosculis 4—5 inferioribus neutris, \\m- 

 paleaceis, nervoso-costatis, intcrstitiis pubescentibus vel hirsutis ; penultinio neutris simillimo, 

 bipaleaceo, hermaplirodito, paleis subiequalibus. Palea superior angusta, in suleo canaliculato rudi- 

 mentum pedicellatum recipiens. Genitalia et caryopsis ut in genera descripto. 



Bory, in the Itinerary quoted above, gives a very good drawing and interesting descrip- 

 tion of this plant. He says it is a most beautiful grass, flowering in September and 

 October, when the stamens are exserted and hanging from the spiculse. It is quite an 

 alpine plant, and forms a well-marked and remarkable belt all round the island of 

 Bourbon, interrupted only in places where the flow of lava prevents vegetation. 



Species valde incerta et sine dubio anomala, stylo bifida. 



2. N. BARBATUS, Trin. in Act. Petrop. I. c. 627, sub nom. Bambiisa harhata. " Sjiiculis 

 sessilibus, in fasciculos dense aggregatis, 5-floris, foliis latis, ovato-oblongis, basi 

 subcordatis." — Euprecht, /. c. 132, tab. xvii. fig. 41 ; Steud. /. c. 332. 



Hah. in Brasilia, in collibus sylvaticis Bumadinlise, Riedel. s. v. Ruprecht. 



" Cultnus 20-25 -pedalis, raniis paniculatis, ad internodia ramulos 2-3-nos, basi floriferos, medio oligopliyllos 

 vel apliyllos, apice spiculas capitatas emittentibus. Folia ovato-oblouga, 6-84 poll, longa, 16-18 lin. 

 lata, basi rotundata, subcordata, longe pctiolata, plicata, opaca, nervis secundariis 10-11, venulis 

 transversis infra prominulis remotis. Vagina infra petiolum 3-linealem dense unilateraliter sericeo- 

 barbatse, ore fimbriatae. Spicula in fasciculos dense aggregatae, sessiles, 3-5 lin. longse, 4-5-florae, 

 glumis inaequalibus, obtusis (interdum gemmiparis ?) Flosculi 2-3 inferiores neutri, Isevigati, glabri, 

 nervosi, glumis similes. Palea inferior (flosculi penultimi hermapliroditi) acuta, superior involuta, 

 pedicello flosculi sterilis longo, firmo. Squamulce sequales, lanceolatae, nervosae. Stylus superne 

 bifidus. Caryopsis hirsuta, attenuata." " Quoad spiculas affinis N. Borbonico, quoad liabitum 

 autem Guaduce distortm." — Ruprecht, desc. et icon. 



It will be observed from the above description, which is the only acquaintance I have 

 with this plant, that it is widely separated from Nastns Borbonicus, especially if the 

 drawing is correct, in the glumes being occasionally gemmiparous. I do not feel certain 

 to what genus it does really belong, and have therefore kept it where Euprecht 

 placed it.
