paragraph. Regarding the plant from Lake Winnepesanga, both Durieu and I will ignore 

 it completely. 



The North East is therefore like the North West, full of clouds and isoistic problems 

 waiting for your advice from Europe. It would be nice if you could furnish us with some 

 material necessary to résolve the doubts of the extensive information available after the 

 collection done during the good seasons. You will have little time because of your 

 médical practice and for financial reason. Your friend Mr. Gray, who is crushed by his 

 numerous publications, is also too busy. However he found in Mr. W. Booth from 

 Boston, a man with spare time and good will who will go and explore this year during the 

 best seasons, Echo Lake and Lake Winnepesange after already being acquainted with 

 the Isoetes. Until now he was a novice at Woburn and at Echo Lake. I gave him ail the 

 information that I had and Durant wrote me that even you, were so kind as to give him 

 ail the information about your expériences at those sites. I thank you a thousand times. 

 You understand that this Mr. Booth is the same one who sent me, not long ago dried 

 and living Isoeted from Horn Pond, close to Woburn, Massachusetts. 



Even though I was working in this manner the Isoetes, in North America, helped by a 

 few friends, I remain no less active in Europe. 



For this purpose, my 76 years, went to North Wales last year. Two motives called me to 

 do this, one being that that country is the cradle of the gender Isoetes. It is the first 

 place on earth that furnished the samples destined to the création of this gender. In the 

 second place my motives were to hopefully observe, one next to the other the living 

 plants representing in the site, the two species that I new grew: lacustris and 

 echinospora. I had already done this one year ago in the mountains of central France. 

 In spite of my poor legs, this goal was accomplished perfectly, thanksto the assistance 

 of an intelligent guide and mostly to Professor Babington who came to join me at 

 Flanbaris and who made several difficult hikes for me. The results are in the first place, 

 that the Lacustris grows in large numbers in the small lakes in the vicinity of Snowdon 

 and in the second place that the Isoetes echinospora is extraordinarily mixed with the 

 lacustris, but in such small numbers that after furnishing Braun and Durieu I was only 

 able to keep what was strictly necessary. Another unusual fact that came from the 

 expérience acquired in this voyage is that at a latitude of 10 degrees north, the 

 maturation of the macrospores of the Isoetes is retarded by several months. Not only 

 did I not find a single mature spore at the end of August, which is the same time as they 

 were perfectly ripe at superior élévations in central France. Several packets were made 

 available to me from the same place, since I returned and up to December 15. Even at 

 this late date the spores had not matured. Therefore thèse two species can only be 

 distinguished by their color which leaves many doubts. It appears however that 

 Babington had well formed macrospores for his drawings of the isoetes echinospora in 

 the Seeman Journal of Botany, taking a French sample to sketch from. 



There it is, what I did on English soil. On the continent I wrote a great deal, on many 

 subjects as did also Braun. In this way we acquired much information on the 

 geographical distribution of the Isoetes lacustris and the echinospora. Now we can 

 observe it from the Pyrénées to areas far in the north nearly up to the Artic Circle (the 

 echinospora). However and due to our information, it is apparent that north of the 44th
