P. 638. Under 3. P. EUPHRATICA, for Balsamiflora read Balsamifera. 



P. 610. EPHEDRA. As this sheet was passing through the press, I received a 

 copy of Dr. Stapf's elaborate "Arten der Gattung Bphedra," published in the 

 56th volume of the " Denkschrift der Mathem.-Naturwissenschaft. Classe der Kais. 

 Akad. der Wissenschaft " (Wien. 1889). The conspectus of his views which I here 

 give will enable Indian botanists to estimate the value of the characters adopted 

 for the discrimination of the species of this most puzzling genus. With the excep- 

 tion of the few references between brackets ( ), the following is a translation from 

 Stapfs memoir.
