OF THE GENUS RESTIO. ` 251 
Culmus 2-3-pedalis, erectus, teres v. subcompressus, crassitie pennae 
corving, versus medium dichotome ramosus, ramique ascendentes, 
elongati, olivacei, tuberculis albidis parvis obsiti, iterum subfascicu- 
latim ramulosi, ramulis ultimis diffusis, filiformibus, rigidiusculis 
(aphyllis?). Vagine, nisi ad ramificationes, arctz, ellipticze, striate, 
marginibus superne membranaceis, sub apice obtusiusculo setaceo 
aristate. — Spicule in apice ramulorum solitarize, ovato-oblonge, 1-2 
lin. long., vix 1 lin. lat., pluriflore. — Bractee laxe patentes, oblonge, 
coriacez, ferruginez, sub apice membranaceo acute mucronate, flores 
oblongos vix superantes. Glume externe 3, equales, oblonge, rigidius- 
culz, pallide ferrugineæ, laterales duz conduplicatz, ad carinas ferru- 
gineo villose ; glume interne 3, externas longitudine zequantes, lati- 
tudine autem eas superantes, oblongz, spathulate, chartacez, pallide 
ferruginee. Staminodia nulla? Ovarium ut videtur oblongum, sub- 
trigonum, stigmatibus linearibus villosis tribus superatum. 
The specimen examined was too imperfect to allow of the struc- 
ture of the ovary being satisfactorily determined. Sprengel is 
stated by Nees (UL ei to have referred this plant to the genus 
Thamnochortus.

Kunth has erroneously placed this species in the two-styled 
section. The female flowers have staminodia and a trigonous two- 
celled ovary surmounted by three styles. 
R. suBTILISs, Nees, MS. Culmis sterilibus erectis, subcompressis, fili- 
formibus (sesquipedalibus), suleatis, parce dichotome ramosis, ramisque 
tenuissimis, erectis, longissimis, remote vaginatis, stramineis : culmis 
fertilibus consimilibus, longioribus, supra medium ramosis; vaginis 
arctis, tubulosis, unguicularibus, coriaceis, sulcatis, marginibus superne 
vix membranaceis, sub apice obtusiusculo foliaceo-mucronatis ; spiculis 
remotis, in paniculam laxam cymosam elongatam dispositis, sessi- 
libus v. longiuseule pedicellatis, singulis ovatis, acutis, bifloris (vix llin. 
longis, 3 lin. lat.); bracteis arcte imbricatis, late ovatis, coriaceis, fuscis, 
marginibus superne membranaceis, apice vix acuminato-mucronatis ; 
floribus (masculis) ovatis, subcompressis, bracteis stipantibus, vix 
brevioribus; glumis externis ovato-oblongis, rigidiusculis, pallide 
fuscis, lateralibus conduplicatis, vix carinatis; glumis internis aqua- 
libus, conformibus, vix brevioribus, hyalinis; antheris linearibus, 
flavis; pistilli rudimento minuto, trigono : spiculis femineis ut in mare, 
nisi numero paucioribus magnitudineque parum majoribus ; stami- 
nodiis ligulzeformibus ; capsula trigona, triloculari (trisperma?), angulis 
salientibus dehiscente, superne stylorum vestigiis coronata, purpurea.
