P. ffavido affine; culmi inferne valde robusti, superne graciliores, erecti, usque ad apicem foliati, 

 cum paniculis circa 4 dm alti ; folia unacum vaginis glaberrima laeviaque; vaginae infimae elongatae, 

 dilatatae, demum subpatentes, uti caeterae omnes glaucae et striatulae ; laminae usque 2 dm longae, planae 

 et usque plus 4 mm latae, subtus glauco-pallidae , dum siccae plerumque marginibus involutae, striatae, 

 glabrae laevesque; ligulae in cilias breves dissolutae; lamina folii culmei supremi paniculae dimidium saepe 

 superans; panicula circa 10 — 15 cm longa, parte inferiore ramos breves, distantes, spiculigeros . parte 

 suprema spiculas singulas, approximatas gerens; paniculae rami infimi circa 2 cm longi, spiculas six vel 

 septem magnas, fere monostichas vel interdum indistincte distichas, haud imbricatas gerentes ; rami superiores 

 simpliciores ; spicula suprema rami cuiusque rhachide aristifornh sterili circa 6 — 8 mm longa fulcrata; 

 spiculae distincte sed breviter pedicellatae , pallidae, valde tumidae, fere globosae, breviter acutae, circa 

 4.5 mm longae et totidem latae: glumae glumellaeque subrigidae; gluma I. valde concava, spiculam per- 

 fecte amplectens, latissima, breviter acuta, 7 -nervis, spicula circa dimidio brevior; gluma IL latissima, 

 semigloboso-concava, pro more 13 nervis, nervis prominulis; gluma III. similis 11 — 9 nervis, dorso bicarinato- 

 impressa, nervis minus prominentibus, palea vix breviore, acuminato-mucronata instructa: glumella perfecte 

 laevis (nervis obsoletis), breviter apiculata. 



Queensland: Springsure (Wuth) ; Peak Downs (Burkitt). 



Species distincta, spicularum dispositione et dimensionibus, rhachi aristiformi, glumis multinervibus, 

 nervis prominuhs etc. excellens; P. flavidtim , cui species nostra affinis esse videtur, jam spiculis dense 

 biseriatis , pro more valde incurvis et minoribus, glumis tenuioribus, glumarum nervis minus numerosis 

 facile distinguitur. 



405. P. retiglume Dom. in Fedde Repertor. IX. 199 (1911). 



Habitu P. flaiido simile; culmi fasciculato-caespitosi , foliati, molles, 4.5 — 5 dm alti; folia mollia 

 laeviaque, convoluta, unacum vaginis glaberrima; panicula elongata, usque plus 2 dm longa: paniculae 

 rami distantes, suberecti, circa 2 cm longi, omnes usque ad paniculae apicem similes; ramulorum rhachi* 

 fiexuosa, compressa, dilatata, circa 0.75 mm lata, apicenuda; spiculae subsessiles, distichae, densae, parvae, 

 vix 3 mm longae; gluma I. membranacea, amplectens, truncata, obtusissima. interdum in apicem parvum, 

 acutum contracta, pro more 3-nervis et quam gluma IL subtriplo brevior; gluma IL gibboso-multinervis, 

 nervis circa 11, interdum nonnullis intermediis apice evanescentibus, omnibus prominulis et conspicue 

 transverse reticulatis; gluma III. similis sed longiuscule acuminata; palea lata; glumella acuta, subtiiiter rugosa.
