POUR SERVIR A LA CONNAISSANCE DES CYCADÉES. 69 
6. M. Macleayi Miq. n. sp. Truncus (junior) ovoideus ; folia 
distincte petiolata, petiolo trigono-cylindrico basi villoso ; foliola 
antrorsum erecta facie superiore ob levem baseos antice incras- 
satæ et puniceo-coloratæ torsionem sursum spectantia, numerosa, 
lanceolato-linearia spinoso-acuta versus basin et apicem parum 
anguslata, coriacea, rigida, subtus pallidiora 6— 8-nervia, lati- 
tudine maxima in medio obvia ; genitalia incognita. 
Exemplaria sterilia quae juvenilibus M. Fraseri non absimilia, aliis no- 
tis ad M. spiralem et M. Miquelii spectant, ab his autem trunci et petio- 
lorum baseos villoso indumento, ab omnibus foliolis basi rubro-pictis et 
antrorsum erectis (unde lamina antice canaliculata) facile discernitur. 
In hortis non nisi junior exstat, adulta quantum e semine quod habeo 
concludere licet, probabiliter staturam M. Fraseri æmulans. Specimen 
vivum horti Rheno-Trajectini : truncus ovoideus squamosus, squama- 
rum vestigiis et lanugine propria parce griseo-villosus 1 pedem altus; fo- 
liis duobus. Petioli semipedales virides nitidi basi antice et postice - 
compressi, cæterum trigono-cylindrici ; lamina folii 12-2 pedes longa, ob 
pinnas antrorsum directas non plana ; foliola utrinque 48, ima breviora 
sed reliquis æquilata, summa breviora et angustiora, reliqua omnia con- 
formia, supra saturate viridia hic illic verrucellosa, nitidula, subtus 
pallidiora et nervis 6-8 vulgo 7 striulato-subdepressis notata interque 
eos stomatifera, apice pungenti-spinoso-acuta, a medio versus basin et 
apicem regulariter angustata, ima basi presertim antice et in axilla glan- 
duloso-subeallosa et rubro-puniceo- colorata (unde elegans folii facies) ; 
medic frondis 51-6 poll. longa, 2-21 lin. in medio lata; rachis sursum 
valde angustata, tota utrinque sulco longitudinali exarata. Supremis fo- 
liolis macula rubra deest. — Folia novella tota lanuginosa, adulta præ- 
ter basin glaberrima. 
In foliis a Van Houtte nomine Catakidozamiæ Mac Leayi missis, alio- 
rumque hortorum nomine Cat. Mackenzii vel Mackeani (ex errore pro- 
babiliter), e seminibus ad Moreton-Bay lectis educatis petioli novempol- 
licares deorsum semitereti-compressi, lamiræ 1-pedales, foliola utrinque 
28, media 71 poll. longa, 13-fere 2 lin. lata, suprema basi leviter decur- 
rentia. Semen, cujus tantum pars lignea adest, 12 poll. longum, inæquila- 
teraliter obtuso-4-sub-5-gonum, faciebus 2 multo latioribus, ellipsoi- 
deum, utrinque obtusum, iis M. Fraser? non absimile. 
Nascitur in Nova Hollandia orientali, in regione fl. Moreton, 
ubi probabiliter detexit Mac Leay.
