Obs. Ordo medium tenet inter Restiaceas et Asphodeleas ; 

 ab illis Embryone incluso ssepiusque radicula centripe- 

 ta, et staminibus dum tribus foliolis exterioribus perian- 

 thii oppositis : ab Asphodeleis integumenti seminis peri- 

 anthiique textura, et ijabitu diversus.

Junci species. Linn. Juss. Cephaloxys, Marsippospermum, 

 Rostkovia. Desvaux injourn. debotan. 1. p. 321. et seq. 



Perianthiwm 6-partitum, glumaceum, bibracteatum. Sta- 

 minaQ, v. 3. Stylus brevis, Stigmata 3. Capsula 3- 

 locularis, (raro subunilocularis) 3-valvis, polysperma. 

 Folia glabra, cylindracea v. carinata, nunc plana adversa, 

 quandoque planb-compressa verticalia. 



Obs. A Junco haud separandae sint species triandrse, quia 

 invicem dissimiles habitu et capsulae dissepimentis comple- 

 tis v. semicompletis obsoletisve. Nec secernendse eae semi- 

 nibus scobiformibus, testa nempe, quse in pluribus utrin- 

 que laxa, in his valde elongata : inter se enim capsularum 

 structura pariter diversse sunt. Genus autem his charac- 

 teribus commode distribui posset in phalanges, ad quarum 

 posteriorem inter Europsas pertinent Juncus triglumis L. 

 biglumis L. castaneus Smith. horum omnium folia aversa 

 plus minus compressa, ideoque duplici nota Nartheeio 

 Huds. conveniunt, et transitum ad Asphodeleas facilem 

 reddunt.
