368 Dr. WarkEn-AnNorT on Samara leta, Linn. 
1 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, paulló ultra medium quandoque feré ad basin quadri- 
fidus, segmentis latè triangularibus, acutis vel obtusiusculis, ciliolatis, zestivatione remo- 
tiusculis. Masc. Corolla calyce quadruplé longior. Petala quatuor, imo calyci inserta, 
sessilia, separatim cadentia, ovato-oblonga, obtusa, ciliolata, zestivatione imbricata peta- 
lis duobus exterioribus duobus interioribus (in exempl. Banks.: fusca lineolis crassis 
brevibus atro-fuscis obscuris punctata, dorso sublevia, inferné versus marginem quasi 
introflexum et ad basin crassiuscula, medio intüs supra staminis insertionem subca- | : 
naliculata, apice plana tenuiora; in exempl. Linn.: viridi-brunnea, glandulis rotundis - 
crebris conspicué notata et dorso subasperata, ad basin intüs utrinque incrassata, sur- - 
sum concava, vix ac ne vix canaliculata, apice tenuiora). Stamina quatuor, petalis 
opposita et paulló supra basin inserta (im exempl. Banks.: corollà sub-breviora, 
filamentis latè subulatis ad petalorum canaliculum applicita; in exempl. Linn.: in ala- 
bastro corollà dimidio breviora filamentis brevissimis, in flore explanato filamentis 
filiformibus corollam feré dupló superantibus). Antherae medio dorso affixe, con- 
nectivo latiusculo, erecta, introrse, glandulá apicali destitute, biloculares, loculis — 
longitudinaliter e basi versus apicem dehiscentibus (im exempl. Banks.: subrotundis, | d 
basi apice subemarginat:z, filamento vix breviores; im ezempl. Linn., saltem in ala- 
bastro*, cordate). Pollen minimum, ellipsoideum, leve.  Pistillum imperfectum, 
liberum, minutum, calyce brevius, ovato-conicum, fuscum. Fam. Corolla quam in 
masc. major, calyce 4-5-plà longior. Petala quatuor, imo calyci inserta, sessilia, ovalia, 
obtusa, margine copiosé ciliolata, brunnea, ad basin lobulo inflexo intüs adnato utrin- 
que incrassata, concava at medio supra staminis insertionem haud canaliculata, superné 
tenuiora, glandulis rotundis conspicuis aurantiacis punctata et dorso subasperata, 
&stivatione ut in masc. Stamina quatuor, petalis opposita et paullo supra inserta, ac 
lisdem subdimidio breviora. Filamenta subulata at brevissima. Anthere cordate, = 
majusculz, subcerez, polline nullo. Ovarium liberum, 1-loculare, receptaculo magno - 4 
globoso libero centrali sessili, ovatum, apice in stylum conicum corollá brevius (in 
exempl. suppet. flexuosum) angustatum. Stigma dilatatum, medio depressum, margine - 
obscure fimbriato-acerum. Ovula pauca, duo (an semper ?), receptaculo supra medium - 
immersa, lentiformia. 
— Rami cinerei, in exempl. Linn. masc. subleves, in foem. lenticellis crebris notati. 
| Folia veta oblonga, integerrima, obtusa, basi paulld angustata, pallida, subtus tamen p 
pallidiora, glaberrima, tenuia ac minim? coriacea, lineolis fuscis crebris punctisque pii- —
