Of Drege's specimens, I refer the following to Brtinia: 

 B. verticillata {B. virgata Brongn.,) No. 6856. h, B. Race- 

 ?nosa. No. 6854. c. and B. macrocephaJa : as also Bernardia 

 lavis, and perhaps Linconia tamariscina. To Staavia, St. 

 glaucescens, No. 6873, a, and St. radiata. To Berzelia; 7?, 

 lanuginosa. No. 6863, 6864, 6862, c, and 6857. a. To Ras- 

 pallia ; R. teres, No. 6868, R. angulaia, Brunia pkylicoides, 

 Br. capitellata, and perhaps Br. villosa: this last has the habit 

 of the second section of Brunia, but the stamens are inclu- 

 ded : the structure of the ovary is as in Raspallia. To Titt- 

 mannia belongs Brunia lara E.M. and apparently also of 

 Thunberg. Under Berardia ought to be brought Brunia 

 paleacea, which indeed is the type of that genus. From the 

 whole order must be excluded Raspallia No. 6869, wliich is 

 Griesbachia incana, one of the Ericinece. 



26. Passijlorecje. — Modecea septemloba E. M., is Ceratosieyos 

 Eckloni N. ab E. ; a genus, which with Acharia, has been 

 already commented upon in i\\e Annals of Natural History, 

 III. p. 420.
