NOTE ON VAYJEA AND RHYTIDANDRA. 
to the Cornea , and then to Nyssacece .* Lindley has adopted Brongniart’s suggestion, 
and referred both Nyssa and Mastixia to the Alangiacece .j* 
I may add, that the fertile flowers of Nyssa 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 hegoniafolia , 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 Rhytidandra and Marlea is therefore 
immediate. The essential differences between them are correctly enumerated in a 
preceding paragraph.
