Mr. Brown, on the Proteacece of Jussieu. 51 



Nux V. Samara monosperma, squarnis (quandoque cohacrcn- 

 tibus) strobili iiickisa. 



Habitus. J'Viitices, rard Arhores, scepc sericeo-lomentosi. Folia 

 iniegerrima. Capitiila terminalia, solitaria ; bracteis imbricatis fo- 

 liisve verticillatis et subcoloratis pkrmnque ciiicta. 



Obs. The separation of sexes in the genus Protea of autliors, ob- 

 scurely suspected by Linnueus himself in his Protea parvijiora, 

 and afterwards more expressly by Lamarck in P. pinifo/ia^ was- 

 first ascertained in Julax and the present genus (as Mr. Dryan- 

 der informs me) by our countryman Masson, d-uring his last re- 

 sidence at the Cape of Good Hope, and is beautifully illustrat- 

 ed by that eminent botanical painter Mr. Francis Bauer, in his 

 -unpublished drawings preserved in the Banksian collection. 

 Numerous observations on the same subject have also more 

 recently been made t>y Dr. Roxburgh and Mr. Niven, who have 

 bestowed much pains in ascertaining its limits, of which, as 

 far as regards the African part of the family, Mr. Salisbury has 

 given an accurate account in his Essay already quoted. The Dis- 

 sertation of Thunberg, who was wholly unacquainted with this 

 separation of sexes in these plants, is necessarily imperfect, 

 and he has, in several cases, described the different sexes as di- 

 stinct species ; and thus also Bergius has founded his genus 

 Au/ax on the male of a species, whose fenjale he had previously 

 published as a Leucadendron. On the other hand, Jussieu', 

 deceived by the resemblance in inflorescence, between Bra- 

 bfjum and the spiked species of Protea, has erroneously 

 suspected these to be monoicous, while he has totally over- 

 looked the truly dioicous nature of the present genus.
