336 NOTE ON VAV^EA AND RHTTIDANDRA. 



to the Cornea:, and then to Nyssacece.* Lindley has adopted Brongniart's suggestion, 

 and referred both Ni/ssa and Mastixia to the Alanrjiacea.-f 



I may add, that the fertile flowers of Ni/ssa sometimes exhibit a double perianth, 

 namely, five minute rounded lobes or teeth belonging to the border of the adherent 

 calyx, and alternate and within these as many small, ovate petals. 



*^* (November 13.) Flower-buds of Marlea hegoniafoUa, received through the 

 kindness of Sir William Hooker just as this sheet is about to go to press, verify the 

 suggestions given on the preceding page, both in respect to the aestivation of the 

 corolla, which is truly valvate, and as to the nature of the anthers, which are simple 

 and quadrilocellate, not united in pairs as described by Lindley. Nor, in the flower-buds 

 examined, are the anthers in the least coalescent into a tube. The generic character 

 assigned by De Candolle is therefore correct as far as it goes. That of Endlicher 

 is incongruous as regards the stamens, he having adopted the view of Lindley without 

 consistently carrying it out, and erroneous as to the aestivation of the corolla, probably 

 from having transferred this point of Wight and Arnott's character of the Alangiea 

 to the genus Marlea. The relationship between Rhytklandra and Marlea is therefore 

 immediate. The essential diff"erences between them are correctly enumerated in a 

 preceding paragraph.
