86 GENERAL REMARKS ON THE 



CORTSANTHES FIMBRIATA. Tab. 10. 



Corysanthes fimbriata. Prodr.fl. nov. holl. 328. 



In shady places, especially under rocks and large stones, near Sydney, and 

 in other parts of the colony of Port Jackson. 



DE8C. Bulbui solitarius pisiformis radicem longam teretem fibris nonnullis 

 alternis simplicissimis instructam terminans. 



Folium vinicum, quasi radicale, sed caulem brevissimum demersum, basi 

 squama unica semivaginanti subovata acuta instruotum terminans, subrotundum 

 mucrone brevissimo, basi altfe cordata, lobis posticis rotundatis altero alterum 

 equitante, explanatum horizontale, viride subtus dilutius, diametro subunciali, 

 venosum venis dichotomis crebre anastomozantibus in nervummargini approxi- 

 matum et parallelum desinentibus. Flos solitarius, pro ratione plantae magnus, 

 purpureus ; ovario intra folium subsessili postice bractea semilanceolata erecta 

 subtenso. Pma^zttzam petaloideum sexpartitum ringens : Foliolatria exteriora, 

 quorum Oalea hyalina cum maculis crebris purpureis insequalibus, e basi erecti- 

 uscula arouata angustiore, superne dilatata obovata magis concava porrecta, 

 apice incurvo, marginibus longitudinaliter nndis ; duo aniica cum lateralibus 

 interiorum labium inferius descendenti-porrectum efformantia, subulata plana 

 alba immaculata, ipsis basibus invicem connatis : tria interiora, quorum duo 

 lateralia anticis exteriorum similia, e basi brevi porrecta adscendentia. La- 

 bellum maximum unguiculatum indivisum ; ungue brevissimo erecto albo : 

 lamincB dwiidio inferiore adscendenti galeae basi appte^so, marginibus nudis 

 injflexis tubum completum efformante, intus nigro sanguineo sursum dilutiore, 

 paulo infra apioem albo virescenti rugoso subglanduloso ; superiore dilatato 

 ovato concavo deflexo, dilute purpureo maculis numerosis confluentibus rufo- 

 sanguineis, disco intus paulo infra apicem glandulis sessilibus sparsis ornato 

 marginibus inflexis fimbriatis lacinulis subulatis sequalibus. 



Columna fructificationis inclusa, brevissima, adscendens, alba carnosa, basi 

 parum coarctata, apice postice trifido dentibus lateralibus erectis subulatis in- 

 fill] termedio antherifero. Anthera mobilis ovata membranacea purpurascens 

 apice semibifido, unilocularis, apicem columuse incumbens. Massce Follinis 4, per 

 paria cohaerentes, farinacese, apicibus affixse glandulie communi emarginaturam 

 stigmatis operienti. Ovarium oblongum : Stylus cum basi columnse conferru- 

 minatus : Stigma solntum, horizontale subrotundum, antice conoavuiti, apice 

 plica duplici coarctatum, antherse subparallelum. 



Ohs. The three species of which this genus at present 

 consists agree in their anthera being unilocular after burst- 

 ing, in the singular relative proportions of the parts of the 

 perianthium, and in habit ; but in some points, generally 

 of importance in this order of plant ''j they differ very 

 remarkably, especially in the form ot the labellum, which 

 in one species is even furnished with a double calcar. 

 Corysanthes may therefore be considered as affording a 

 proof, and many others might be adduced, of the superior 

 importance of certain modifications of the anthera to those 

 of the labellum in Orchidese.
