Spicai f-1^ unciam longse, pennae anserina; minoris crassitie. Spicule lineam longie. Squamaruni ner- 

 vus carinalis viridis basin versus tenuis sursum validior et latior, denique in mucronem etiamque virideni 

 rectum vel patulum validum procurrens. Squamm dua; inferiores minorcs et sterilcs. 



We have given the above character, in order that it may be compared with that of C. diijitatus, traced 

 by Nees Von Esenbeck, 1. c. (where the leaves and involucres are said, by a typographical error, to be 

 " margine rubris," instead of " margine scabris,"): and the two will be found scarcely to differ. Nees Von 

 Esenbeck, in his MS. remarks of this plant, " distinguitur inter confines spicis in radiis umbellute 1-2-polli- 

 caribus quinis senis septenisve, f-1 pollicem longis, 3-4 subaequalibus majoribus, reliquis minoribus, crassitie 

 pennas anserina?, a basi, ubi quandoque nonnihil curvantur, densissime imbricatis, manum cum digitis suis 

 bene referentibus :" the first part of which agrees with our one, but the latter is not so evident either in the 

 specimen before us, transmitted for our inspection by Professor Henslow of Cambridge, or in Roxburgh's 

 description and figure, with which the Chinese plant agrees exactly.]

Vera Iriarum socia, spiculis angustis, squamisque alternatim dispositis, dorso viridibus, laeviter quinque- 

 nervibus obtusissimis cum vel sine mucronulo, margine albido membranaceis caryopsin aequantibus bene dis- 

 tincta. Stamina 3. Involucella 3-4-phylla, lineari-setacea, umbellam sequantia.

1. M. cyperinus. Vahl.—N. ab E. 1. c. p. 90. (cum char, et syn.)— Vachell, n. 73. a. 



Spicule vix linea aut sesquialtera longiores, lineari-subulata?, e 4 vel 5 squamis exstructse, quarum inferior 

 patula, lanceolato-subulata, spicula triplo brevior, secunda ovata, obtusa, hac autem sterilis; turn tertia ex- 

 teriorque major ovato-lanceolata primo in subulam convoluta, dein obtuse carinata, margine alba, dorso 

 viridis, trinervis, amplectens in spicula uniflora alteram flosculum minorem angustioremque et sterilem, in 

 bifloris quarta sequitur squama, tertiae conformis eademque fertilis, \-^ longior. Stamina tria, valvula lon- 

 giora. Stylus ad medium trifidus. Caryopsis oblonga, obtuse trigona, Isevis. Structura spiculae in uni- 

 floris omnino Kyllingim, nullaeque adsunt rhacheos ala? valvulare3 hie autem in bifloris adsunt distinctissimse, 

 apice liberae. Turn vero inflorescentia, valvule convolute; nee carinatse, stigmata tria et caryopsis trigona 

 Mariscorum. Folia culmo plerumque breviora sunt, uti et in icone Rheediana. (Hort. Mai. 12. t. 63.) In- 

 volucrum 3-6-phyllum, foliolis plerisque umbellam excedentibus. Spicula adultae et fructifene patentes et 

 subreflexae. Color foliorum glaucus.
