Planta spithamaiia usque tripedalij', cnjus stirpes niasculae femi- 

 neis multo freqnentiores. Folia |-3'" luta^ iu locis silvaticislaxiora, 

 in apertis rigidiora. Panicula interdum ad racemtim simpliciter 

 verticillarem reducta.» Flores usque 50 in verticillo. Pedicelli 

 florum masculorum capillares, semiunciales v, breviores, nonnuu- 

 quam vix calycem longitudine ffiquantes. Calyx masculus circiter 

 sesquilineam longus^ dum iuexpansus fere pyriformis ; sepala 

 exteriora dorso magis minusve purpurascentia ; interiora lute- 

 scentia et apice paulo protracta. Filamenta alte aduata, Auther» 

 ovata?, paulisper cordatoe. Calyx femineua masculo rigidior, 

 2-2^'" longus- Capsula 3-4'" alta^ apice non depressa. Semina 

 oblique ovata^ 2'" longa^ livida.

X, dura (F, ]M. in Transact. Vict. Inst. 1855, p. 42, Sond. in 

 Linnaea^ 1856, pag. 219), quam prope sinus St. Vincent's et 

 Spencer*8 Gulf et montes EIder's Range detexi, calycibus mas- 

 culis sessilibus basi minus insigniter protractis, sepalis florum 

 femiueorum latioribus et brevioribus sicut capsula la^vi minore 



prtecipue a X. Brownii distinguenda et ulterius observanda est. 



Xerotcs suaveolens (Endl. in Lehm. Plant. Preiss. ii. 50 ; X. 

 umbrosa, Eudi. 1. c.) ad fluvios Canning-River et Swau-River a 

 Preissio detecta fuit, e cujus collectionibus planta mascula mihi 

 anteponit. Folia ^-1'" lata ; basis amplexans mox infibras soluta. 

 Flores ^impliciter capitati vel breviter glomerato-spicati. Bractese 

 involucrantes pallldae, acutiusculoe, haud nitentes^ floribus tene- 

 riores. Calyces ferc medio tenus tubulosi, deorsum sensim valde- 

 que attenuati, epedicellati^ in lobos fere £equales fissi, 2-3'" longi, 

 basi bracteis hyalinis sfepe ter brevioribus stipati. Antherte prope 

 faucem calycis sessiles, aliquoties longiores quam latiores. Fila- 

 menta adnata. Species j uxta X. glancam in systema bene inseretur. 



' X. sericea (Endl. I. c. p. 51) certe e genere excludcnda.
