368 Dr. Walker-Arnott on Samara leeta, Linn. 



I shall now add the analysis I have made of the Samara, keeping distinct, 

 when necessary, the three forms spoken of. 



Flores abortu dioici. Calyx minutus, pauUo ultra medium quandoque fere ad basin quadri- 

 fidus, segmentis late triangularibus, acutis vel obtusiusculis, ciliolatis, aestivatione remo- 

 tiusculis. Masc. Corolla calyce quadruple longior. Petala quatuor, imo calyci inserta, 

 sessilia, separatim cadentia, ovato-oblonga, obtusa, ciliolata, aestivatione imbricata peta- 

 lis duobus exterioribus duobus Interioribus [in exempt. Banks. : fusca lineolis crassis 

 brevibus atro-fuscis obscuris punctata, dorso sublaevia, infeme versus marginem quasi 

 introflexum et ad basin crassiuscula, medio intiis supra staminis insertionem subca- 

 naliculata, apice plana tenuiora ; in exempl. Linn. : viridi-brunnea, glandulis rotundis 

 crebris conspicue notata et dorso subasperata, ad basin intus utrinque incrassata, sur- 

 sum concava, vix ac ne vix canaliculata, apice tenuiora). Stamina quatuor, petalis 

 opposita et pauUo supra basin inserta {in exempl. Banks. : corolla sub-breviora, 

 filamentis late subulatis ad petalorum canaliculum applicita ; in exempl. Linn. : in ala- 

 bastro corolla dimidio breviora filamentis brevissimis, in flore explanato filamentis 

 filiformibus coroUam fere duplo superantibus). Antherae medio dorso affixae, con- 

 nectivo latiusculo, erectae, introrsae, glandula apicali destitutae, biloculares, loculis 

 longitudinaliter e basi versus apicem dehiscentibus {in exempl. Banks. : subrotundae, 

 basi apice subemarginatae, filamento vix breviores; in exempl. Linn., saltern in ala- 

 bastro*, cordatae). Pollen minimum, ellipsoideum, laeve. Pistillum imperfectum, 

 liberum, minutum, calyce brevius, ovato-conicum, fuscum. Fcem. Corolla quam in 

 masc. major, calyce 4-5-pl6 longior. Petala quatuor, imo calyci inserta, sessilia, ovalia, 

 obtusa, margine copiose ciliolata, brunnea, ad basin lobulo inflexo intus adnato utrin- 

 que incrassata, concava at medio supra staminis insertionem baud canaliculata, superne 

 tenuiora, glandulis rotundis conspicuis aurantiacis punctata et dorso subasperata, 

 aestivatione ut in masc. Stamina quatuor, petalis opposita et paullo supra inserta, ac 

 iisdem subdimidio breviora. Filamenta subulata at brevissima. Antherae cordatag, 

 majusculae, subcereae, poUine nullo. Ovarium liberum, 1-loculare, receptaculo magno 

 globoso libero centrali sessili, ovatum, apice in stylum conicum corolla brevius (in 

 exempl. suppet. flexuosum) angustatum. Stigma dilatatum, medio depressum, mai-gine 

 obscure fimbriato-lacerum. Ovula pauca, duo (an semper ?), receptaculo supra medium 

 immersa, lentiformia. 



Frutices. Rami cinerei, in exempl. Linn. masc. subheves, in foem. lenticellis crebris notati. 

 Folia alterna, oblonga, integerrima, obtusa, basi paullo angustata, pallida, subtus tamen 

 pallidiora, glaberrima, tenuia ac minime coriacea, lineolis fuscis crebris punctisque qui- 



* There being, as already said, but one flower with exserted stamens, I could not soften it in water 

 so as to ascertain the true form of the anthers ; but there is no reason to suppose that they afterwards 

 differ from what I observed in the bud.
