FLORA OF NEW PROVIDENCE AND ANDROS 129 



number of doubtful specimens were compared by me at Cambridge in 

 1897, and I take this opportunity of thanking Dr. Benjamin L. Rob- 

 inson and his assistants for the kindness then shown me and for a 

 number of determinations they were good enough to make for me 

 the following year. I also wish to acknowledge gratefully several 

 determinations made for me by the authorities at Kew in 1897. 



The new species have been most successfully drawn by Miss Mary 

 V. Thayer, of Holbrook, Mass., to whom I wish to express my thanks 

 for her careful work.^

^ The long period that has elapsed since the collection of these plants and the 

 publication of this report may call for a word of explanation. My husband was work- 

 ing up the zoological collections and I the plants when his sudden death occurred in 

 June, 1891. Since then ill-health has year after year prevented any continuous work, 

 and the frequent lapses of time have made much revision necessary. My husband 

 greatly assisted me in the beginning of the work, and my sole motive in continuing it 

 was because of his interest in my doing it.
