That this is the genus and species described by Eschschotlz we entertain no doubt, especially as we have 

 received specimens so named from Chamisso. In the 5th volume of the Linnaea, p. 86, Chamisso and 

 Schlechtendahl reduce it to Croton, and consider it no way different from C. gracilis of Kunth, from Mexico. 

 Again, Mr Bentham, in his account of Hartweg's Mexican plants, No. 83, makes of Croton gracilis his 

 Astrogyne crotonoides, and expresses his doubts if Mr Douglas' Californian specimens belong to the same, 

 or form an allied species. An attentive comparison of Hartweg's specimens, and of Douglas' with 

 Chamisso's, leave however no doubt on our minds that they all belong to the same genus, but that the Mexi- 

 can species is different from the Californian. The name Hendecandra is certainly not appropriate, but we 

 are unwilling to change it for one so much more recent, and founded on another species. Eschscholtz does 

 not seem correct as to the number or situation of the stamens, and Mr Bentham has omitted to notice the 

 hypogynous disc : the styles are often more divided than is stated by either. Croton gracilis of Kunth or 

 Astrogyne crotonoides, Benth. may be thus distinguished :— H. crotonoides ; foliis breviter petiolatis, racemis 

 masculis elongatis folia fere duplo superantibus.
