Murchisonii extendit, Valva^ fructus e bracteolis auctis ortae 
dorso emergente tuberculato-rugosa^, quo modo planta paulo ad C. 
torulosam (C, tenuissimam Sieb.) et C. microstachyam approximat. 
Brcvitas et densitas amentorum masculorum satis insignes. Semi- 
uum ala truucato-obtusa, mutica, conspicue latior quam longay 
nucleo luceuti-spadiceo semiovato-rhombeo longUudine vix aiqualis. 
Species apparet dioica, Eamuli nunc magis angulati, nunc magis 
teretes, ssepe pallidius virentes. Anthera^ pa^ne latiores quam 
longse. 
Casnarina Huegeliana sequaliter tantum Australiam occidentalem 
extratroplcam inhaLitat a fluvio Phillips River usque ad flumeu 
Murchisonii. Arbor minor, monoica. Strobili maturl ovato- 
cylindracci rarius ovato-globosi, scepe sesquipollicem lougi, passlm 
apice sterili contracti, Seminum nucleus nigro-fuscus, ala mutica 
rotundato-obtusa paulo brevior. 
Casuarina Fraseriana, optime Yer Huellio depicta (in Miq. C 
t. vi, D.) nuper illustro amico C. strictee adscripta est (Ephemer. 
Ratisbon. 1865, 20), abs qua autem fructu valde discedit. Occurrit 
tantum in Australia extratropica occidentali. Bracteola^ valvares 
dorso crassse, tomentellce et veiTuculoso-rugosa^. Seminum nucleus 
fusco-niger; ala cuneato-semiovata, nucleo fere duplo major, mu- 
tica. 
Casuariua strlcta, Ait. Hort. Kew. ed. i. vol. iii. 320, crescit 
sparsim per magnam Australlaa extratropica^ partem tum litoralem 
tura ripariam et rupestrem.

hanc speciem pertinet plauta Sieberi, Flor. Mixt. 605. In mon-
