one or two months. That of P. peltatum, which is known in the 

 United States under the name of May Apple, is of a peculiar light 

 green colour, and is intensely acid. It is occasionally used as a 

 substitute for lemon. 



No plant that I am acquinted with is more impatient of removal 

 or division than Podophyllum Emodi. I was some years before I 

 discovered the cause. On potting some seedling plants two years 

 old, I found only two thread-like roots from two to three feet 

 long, and when these were shortened before repotting, no progress 

 was made by the plant that year. When, however, the roots were 

 unbroken, rapid increase of size took place. 



To grow the plant in perfection, it should be planted in good 

 peat and loam in an open but sheltered situation and never dis- 

 turbed. If moved, it will not bear fruit the following year. It is 

 perfectly hardy, and was introduced in 1845. 



XX. On Chytroglossa. By H. Gr. Reichenbach, fil. 



On looking back to my past life, there is nothing in it that I value 

 more than the intercourse I have enjoyed with so many distin- 

 guished naturalists and travellers. Amongst my most cherished 

 souvenirs, I regard the opportunities I have had of seeing my 

 lamented well-wisher and friend Dr. Lindley at four various times 

 of my life. I enjoyed for more than six weeks his company. 

 During the whole of that time I was at work on his collection of 

 dried Orchids, allowed to make copies of all his drawings, and even 

 to take flowers where they could be spared. The fruits of this 

 activity have enabled me to work with great security, knowing 

 pretty well the Lindley an materials. 



When I met with anything remarkable, I always wrote to 

 Dr. Lindley, who, notwithstanding all his numerous occupations, 

 was ever ready to render justice to any Orchid. I remember very 

 well one foggy November morning, when I made an analysis of a 

 most curious Orchid, of which Dr. Lindley possessed a single 

 zigzag raceme with a few pellucid flowers. The plant had been 

 gathered at Novo Friborgo near Rio Janeiro by the Chevalier 

 Pinel, and Mademoiselle Marie Leonie Pinel had prepared for the 

 Doctor a nice coloured sketch. One flower, the best, was sacri- 

 ficed for an analysis, and Dr. Lindley attended and watched my 

 dissection. I have just now before me my own sketch. There
