158 BOTANICAL NOTES, NOTICES, AND QUERIES. [May, 



I am not acquainted with the other monandrous varieties ; but between 

 these two at least, — whether I have named them above rightfully or not, — 

 would not this difference of colour in the anthers form a useful mark of 

 distinction for those who, like myself, are much puzzled to distinguish be- 

 tween them ? Yet I do not find it anywhere noted. R. E. C. 



" General Post Office, March, 1861. 



" Sir, — In reply to your letter of the 11th inst., I have to acquaint you 

 that books, having specimens of dried plants attached to then." leaves, may 

 be forwarded under the regulations of the Book Post, but that such speci- 

 mens may not be sent loose, nor can seeds be regarded as coming within 

 the privileges of the Book Post. 



" All exchangers of plants have to do, is to have a guard-book made, with 

 thin covers, and (say) about 12 or 15 inches long, by 6 or 8 inches wide, 

 and when sending their specimens, have them securely gummed (by means 

 of slips) to the leaves ; thus the advantages of the Book Post can be se- 

 cured to a numerous body who have perhaps hitherto been ignorant of the 

 privilege. 1 am, yours faithfully, Gr. W. Gissing. 



" Of course no letter must be sent." 



[Several of our correspondents have avaded themselves of this privilege. 

 We have received and also transmitted hundreds of specimens by post. 

 We thank our excellent correspondent for reminding us that this may not 

 be generally known.]
