Descript. Valde variabilis. Perennis, dense caespitosus, gracilis, glau- 
cus (?) Radices filiformes, pallide fuscae, fibrosae, diam. 0,5—0,75 mm. Rhizoma 
horizontale, internodiis brevissimis, caules conferlos emittens, diam. 2—3 mm. Caules 
erecti, graciles, tenues, teretes, in statu humido vix, in statu sicco distincte valleculati 
20—50 (raro usque 80 cm et ultra) alti, diam. 0,75—4,5 mm (raro ultra), medullá eximie 
asterisciformi plerumque lacunoso-interruptä repleti. Folia basilaria cataphyllina, an- 
guste vaginantia, plus minus nitida, straminea, rarius ferruginea vel etiam castanea,

natum (arista usque 4 cm longa); folium unicum frondosum turionis sterilis teres cauli- 
forme, caule brevius. Inflorescentia pseudolateralis, composita, gracilis, ple rumque 
diffusa (raro contracta); rami graciles tenues; flores saepe distantes, secundi. Bractea 
infima erecta, teres, cauliformis, elongalionem caulis simulans, subulata, ca. 8—10 (raro 
20) cm longa, ceterae hypsophyllinae; prophylla floris late-ovata, obtusa, fere toto sca- 
riosa, flore pluries breviora. Flores parvi, 2 usque 3 mm longi, pallide-straminei 
rarius fulvij. Tepala glumacea, aequilonga (vel externa paullulo longiora), externa 
lanceolata, acuta, interna ovata, obtusa, omnia straminea, marginibus latis membra- 
naceis, serius saepe evanescentibus, in statu maturitatis fructus plerumque patentia.

antherae lineares, flavidae, filamenta fere aequantes. Pistillum perigonium subaequans ; 
ovarium trigono-ovatum, obtusum ; stilus brevissimus; stigmata 3. Fructus trigono- 
ovatus (raro trigono-sphaericus, , obtusus, muticus, rarius brevissime mucronatus, ple-

apiculata, pallide ferruginea, regulariter transversim reticulata. 
Var. J. pauciflorus R. Br. var. Gunnii Fr. Bucnexav. Differt a plantà 
typicà: staminibus plerumque 6, catapbyllis basilaribus et floribus intense 
coloratis, fructibus longioribus apice saepe fere castaneis. J. Gunni

recht gute Kennzeichen zu seiner Unterscheidung.

longa, pallida. Flores in glomerulos paucos (saepe 1 usque 3. raro 4 vel 5j

Eine üuBerste Form, welche vielleicht verdient, als besondere Art beschrie-
