growing together. It is therefore necessary to make 

 sure that in every case the shoots selected are taken 

 from one plant. A flowering shoot should be cut 

 off so as to show a portion of the main stem with 

 at least one leaf attached ; then a part of a sucker, 

 or barren shoot, with two or three leaves on it. 

 The plant should be carefully examined to see if 

 the portions taken are sufficient to show all its 

 peculiarities ; if not, some additional parts should 

 be secured. All the cuttings from each plant should 

 be numbered, and any peculiarites of the plant 

 itself noted, so that satisfactory answers may be 

 given to any questions which may be put by a 

 specialist. 



As for Roses, they must have the fruit well formed ; 

 flowers are practically of no use for purposes of 

 identification. If flowers are wished for the herba- 

 rium, the bush from which they are taken should be 

 marked, and specimens in good fruit secured from 

 it later in the season. 



Mints, Grasses, Sedges, and Charas are but little 

 known. 



As I am in constant correspondence with specialists, 

 I shall be glad to obtain an opinion on any critical 

 plants which may be submitted to me.
