rugineae, laves, nervo dorsali in mucronulum abeunte et aliquot cidem adjectis obsoletis preditae, glabrae ; 

 squamaa inferiores aliquot minores et steriles. Stamina tria, filamentis compressis. Perianthium subcylin- 

 drieura, sulcatum, truncatum, ovario angustius, in caryopseos stipitem longum abiens. Stylus compressus, 

 utrinque ciliatus, bifidus, basi bulbulosus et solubilis. Caryopsis obovato-lenticularis, stipitata, filamentisque 

 ad basin stipitis persistentibus cincta, obtusa, subtilissime punctulata, albida, margine discreto obtuso cincta. 



[Mr. Arnott, in Wight's Contributions, p. 97, has pointed out that the var. /3 of Prof. Nees v. Esenbeek, 

 so far at least as relates to the synonym of Scirpus tristacliyus, Roxb., is identical with Dr. Wight's speci- 

 mens of -F. schasnoides, Vahl, as determined by Nees v. Esenbeek himself,]

Species est distinctissima ; quod ad spiculas quidem F. diphyllm haud absimilis, sed statura humiliori, 

 semipedali culmo, foliis brcvioribus subfalcatis ciliatis, plerumque vaginis margine late membranaceis oblique 

 truncatis, umbellaque vix pollicari, bi-tri-quinqueradiata, radiis pollicem longis, longioribus tri-penta- 

 brevioribus mono-di-stachyis, spiculis lateralibus pedicellatis media sessili, in centro spiculis aliquot brevi- 

 pedicellatis congestis, prsesertim autem earyopsi magis compressa, margine. obtuso sulculo discreto cincta 

 utrinque parum convexa costulisque tuberculato-crcnulatis praedita, quarum interstitia angusta lineam puneto- 

 rum insculptorum monstrant. Squama, in nostris, glabrae, subrotundae, obtusse, ferrugineae, costa media 

 viridi in inferioribus brevem mucronulum formante et striis aliquot nervosis lateralibus praeditae. Stamina 

 duo-tria, infra urceolum stipitiformem inserta. Stylus latus, compressus, ciliatus, apice bifidus. Urceolus 

 discretus distincte stipitatus rufulus aut pallidus caryopsin attollit. 



3. F. tomentosa. Vahl. — N. ab E. 1. c. p. 100. (cum char, et syn.) 



Umbellm partiales 4-8-radiatse, radiolis vel omnibus monostachyis, vel uno alterove longiori distachyo. 

 Involucella di-triphylla, foliolis setaceis umbellula duplo ettriplo brevioribus. Squama; spicularum chartacea;, 

 ovatae, brevi-mucronatae, costa viridi, basi albae, superius fuscae, plerumque glabrae. Caryopsis obovata, 

 albida, exteriori latere gibbosa, costis novem, interiori planiusculo costis undecim, interstitiis transversim 

 sulcatis. Culmus sulcato-angulatus, glaber. Folia culmum sequantia vel paulo breviora, linea vix latiora, 

 flava, obtusiuscula, utrinque cum vaginis striata et pilosa. Vaginarum tubus truncatus, altero latere ferru- 

 ginous, punctulatus.

5. F. decora. Nees et Meyen. — N. ab E. I. c. p. 101. (cum char.) 



Rhizoma validum, repens, fibris ramosis sparsis radicans, foliorum culmorumque fasciculos in caespitem 

 collectos gignens. Culmi 4-8 pollices longi, rigiduli, sulcato-angulati, setulis exiguis adpressis inspersi, basi 

 dense f'oliosi. Folia flabellatim disticha e vaginis imbricatis membranaceis ferrugineis subpuberulis fasti- 

 giata, l-li pollicem longa, linea angustiora, attenuata et acutiuscula, apice plerumque sphacelato, plani- 

 uscula, recurva, glauca, supra dense argenteo-sericea subtus sparsim puberula; quae in culmo paullulum ad- 

 scendunt, ad f-i pollicem decrescunt folia, maxima pars culmi aphylla. Involucri folia 2-3, vix 3-4 lineis 

 longiora, basi membranaceo-dilatata, glauca, sericea. Umbelloe radii 3-G, ^-1-pollicem longi, compressi, 

 glauci, cum capitulo centrali sessili. Spiculm 2-4, sessiles, 2-2^ lineas longae, ovato-oblongae, teretes, dense 

 imbricatae. Accedit quandoque in radiis longioribus radiolus brevissimus, distachyus. Squama ovatae, 

 pubescentes, margine late membranaceae albae, pulchre ciliatae, carina dorsali viridi in mucronem excurrente, 

 latere utroque nervis tornis subtilibus. Stamina tria, squama paullo longiora. Stylus ad ^ bifidus, non com- 

 pressus, nee ciliatus, basi bulbosus, latitudine germinis ovalis. Caryopsis obovata, obtusa cum umbone 

 exiguo, fere laevis, pallidc fusca, extrorsum convexa cum vestigiis sulcorum quatuor obsoletis, latere in- 

 teriori planiusculo obtuse carinato. Ad basin caryopseos filamenta ad maturitatcnuisque persistunt.
