tale, in facie inferiore, utrinquc ad lineam medianam, antheras gerens, atque partem elongatam trian- 

 gularem sursum recurvatam et in acumen terminatam. Haec pars in cono integro corpus subjacens 

 antheriferum quasi obtcgit. Corpus horizontale longum est 4 ad 4j centim., et superne 3§ latum. Acu- 

 men fere § longitudinis habet. Spadices inferiores sunt minoies, acumine saepe brevissimo. — Antherae 

 in diias areas collectae sunt, quae areae mediana linea separantur; nec valde confertae sunt; saepe qua- 

 ternatim conjunctae; fissura qua aperiuntur, totam longitudinem occupat. — Conus totus absque pcdun- 

 culo 42 centim. longus est. 



Conus femineus est multo crassior, cylindricus, vel ovali-cylindricus , obtusus, pedunculo crasso, 

 brevi, costato innixus; G centim. longo, 6 — 7 crasso. Axis coni etiam adeo crassus, angulosus, versus 

 apicem parum angustatus. Longitudo coni 42 centim., diameter 21. Spadices pauciores ac in mare, 

 spiraliter affixi, ita ut 6 in sectione transversa appareant. Spadices sunt crassi, pedunculati, pedun- 

 culis sexangular ibus , qui in corpus peltatum, rhomboideurn, margine superius in longum ac adscen- 

 dens acumen elongatum, incrassantur; corporis peltati margines lalerales introrsum recurvati utrinque 

 in fovea ovarium gerunt. Spadices 8 centim. longi, diameter pedunculi 1, corporis peltati 6—7 centim. 

 Superiores spadices majores sunt et longius acuminati quam inferiores. Ovaria angulis oppositis trans- 

 vcrsalibus affixa sunt inversa, ovoidea, inaequalia, paulisper angulosa, pedunculi longitudinis. Nucleus 

 ovoideus, oblongus, 4 et { centim. longus. 



Embiijonis structura similis videtur ac in genere Cycadis (conf. Ron. Browiv 1. c. p. 347. (203). 



Adnotatio. Omnes auctores post Salisburidm, excepto R. Browjv, foliola hujus speciei apice Iri-vel 

 quinquedentata vocant, quod autem nec cl. Browiv descriptio confirmat, nec eximiae Baueri icones. 

 Quam ob rem credere posses , speciem ab his auctoribus recensilam a vera Zamia spirali Salisb. differre. 

 Cum autem cl. Brown suae plantae hoc synonymon addat, hunc sequi consultius videbatur. — An plan- 

 tarum juvenilium foliola dentata? — An Encephalartos tridentatus Lehm. cum hac planta, cui similis, 

 confusus? — Plantac enim, quas nomine Zamiae spiralis vel Encephalarli ^piralis in Hortis inveni, 

 nunquam ad veram Macrozamiam spiralem pertinebant, sed ad Encephalartum tridenialiim vel 

 E. pungentem.; saltem si comparatio instituatur cum iconibus Bauerianis. 



2. MACBOZAMIA FRASERI. 



M. Caudice elato (30 pedum) squamis undique tecto, frondibus. . .. (fere ut in praccedente), conis.... 

 spadicibus spiraliter insertis. 



Habitat in insula quadam ad ostium fluvii Cygnorum J\"ovae Hollandiae occidenlalis (Fraser 1. c). 



Desckiptio et Adnotatio. Prima hujus speciei notitia Carolo Fraser debetur, qui confirmat quac 

 Robertds Brown de specie majore, praecedenti simillinia dixit (Prodrom. Flor. ffovae llollandiae edit. 

 Londin. p. 347. edit. germ. p. 203). Haec Fraseri verba sunt: »The islands on the flats are composed of 

 a rich deposite carried down by the floods. Their margins are covered with Melrosideros and Casua- 

 rina, and their interior with sea-side succulent plants. On one of these islands I caught sight of a plant 

 with an arborescent habit, which, on examination, proved to be a species of Zamia, with spiral 

 fruit, differing only from Zamia spiralis in habit. Here the equatorial Goodenia diappears." (Fraser 

 1. c. p. 227). »One mile up the river, from the last point, is a sinaU creek of fresh water issuing from 

 an extensive lagoon clothed with arborescent species of Metrosideros of great beauty. The banks are 

 covered with the most interesting plants. ... The Zamia, seen from the islands, was here observcd to 

 attain the height of thirty feet. Zanthorrhoea arborea, too, was of equal sizc, and, associated with 

 the splendid Banksias, imparted to the forest a character perfectly tropical" (1. c. p. 229). »It is worthy 

 of remark, that m New South Wales, the presence of Banksia, Zamia and Zanthorrhoea are conside- 



sed sure criterions of a bad soii" 1. c. p. 230.
