orris, valde elevatis et saepius apice longitudinaliter depresso latiusculo marginibus aeutis 
pilosis ; later alibus obliquis dorsum versus tendentibus sensim declinantibus et prope 
medium lateris desinentibus in lineas cursum oblique anticum servantes pauloque supra 
basin ventris coalescentes ; ventrali elevatiore recta, longitudine ascidii, apice semper 
latiusque depresso : Intus nitentia et e majore parte nigro-purpurea, paulo infra an- 
nulum costatum oris aucta margine prominulo integerrimo. Ore plusquam seiniorbi- 
cutari, paulo infra marginem extus cincto annulo tenui, ortum prrebente processubus 
numerosis (19-23), parallelis costreformibus, adnatis, extremitate interiore soluta brevi 
incurva acuta. Operculo e petiolo derivato et postico lateri oris ascidii lata basi inserto, 
foliaceo orbiculato-obovato emarginato planiusculo viridi, venis nigro-purpureis latis 
ramosis apice anastomozantibus picto, extus pilosiusculo intus glabro. 
Scapus simplicissimus erectus pedalis sesqutpedalis villosus pilis simplicibus aeutis, 
instructus bracteis nonnullis alteruis remotis deciduis ; dimidio inferiore quandoque an- 
gulato, superiore semper tercti. Spica terminalis erecta biuncialis, composita spiculis 
numerosis, superioribus confertis, inferioribus sensim remotioribus, omnibus pedunculatis 
4-5-floris, floribus subcorymbosis ebracteatis. Bracteee pedunculos spicularum subten- 
dentes subulate -lineares deciduae. Flores parvi. Calyx albus, alt& 6-fidus simplici serie, 
regularis aequalis, extus pube adpressa simplici, laciniis ovato-lanceolatis patulis apice 
denticulo interiore auctis : basi intus incrassata pilisque capitatis brevissimis bispidula. 
Stamina margini tubi calycis inserts, ejusdem laciniis breviora ; sex laciniis alternantia 
longiora et praecociora : Filamenta subulata erecto-conniventia glabra purpurascentia : 
Antherce conniventes subrotundae didymte, lobis appositis purpurascentibus longitudina- 
liter dehiscentibus, connectivo subgloboso fungoso celluloso albo adnatis : Pollen flavum. 
Pistilla 6 approximata, staminibus minoribus breviora : Ovana cum laciniis perianthii 
alternantia subovata parum compressa glabra, margine ventrali truncato dorsali rotundato, 
monosperma; Ovulo erecto, magnitudine fere loculi et intra testam membranaceam con- 
tinente sacculum magnitudine cavitatis testte, pendulum : Styli terminates teretiusculi : 
Stigmata simplicia. Fasciculus laxus albus villorum centrum receptaculi intra ovaria 
occupat. 
Obs. Cephalotus has been referred by its discoverer Labillardiere to 
Rosace®, to which, notwithstanding its coloured calyx and the absence of 
petals, it seems to have the nearest affinity ; a knowledge of the fruit, how- 
ever, is wanting to determine absolutely its place in the natural method. 
From the structure of its ovulum, even in the unimpregnated state, I enter- 
tain no doubt that the radicule of the Embryo points to the umbilicus of 
the seed and therefore downwards ; a circumstance in which it would
