in-Chief of the Bryologist), that my plant was not Hydrocotyle 

 americana, although the flower resembles it and that it was not 

 H. inter rupta or H. verticillata. Comparisons were made also 

 with specimens from various countries in the herbarium of the 

 Carnegie Museum, and no corresponding type was discovered. 



Upon the advice of Miss Hilda Loines in July, 1931, I sent 

 a living flowering specimen of this Hydrocotyle to Mr. Montague 

 Free, Horticulturist of the Brooklyn Botanic Garden. Mr. Free 

 and Dr. H. K. Svenson, Assistant Curator of Plants of the 

 Brooklyn Garden, were unable to identify it. 



On September 2, 1931, I gave a pressed Hydrocotyle in flower 

 and a living one in fruit to Dr. O. E. Jennings for the Herbarium 

 of the Carnegie Museum, Pittsburgh, Pennsylvania. 



From the original plant found in 1926, Mr. Baxter has sev- 

 eral plants, Mrs. Wadsworth many, there is one plant in the 

 Brooklyn Botanic Garden, and two pressed specimens in the 

 Herbarium of Carnegie Museum, Pittsburgh, one of these in 

 flower, and one in fruit, and I still possess eight living plants 

 in my garden in Pittsburgh. 



The plant has been much admired and is greatly prized by 

 those who have specimens. It is easy of culture if planted in a 

 naturally wet situation or where the ground is kept constantly 

 moist and the plant and ground around it left undisturbed. I 

 use peat moss as an aid in keeping constant moisture, and al- 

 ways plant in the shade. 



After having tried for five years to identify the plant and 

 after having consulted books and authorities, I believed I had 

 discovered a new species of Hydrocotyle. Dr. Jennings has con- 

 firmed my conclusion that the plant is a new species and has 

 furnished the following technical description of the plant: 



Hydrocotyle Fetherstoniana Jennings, sp. nov. 



Planta herbacea; petiolis sparse et minute hirsutis; fructu basi et apice 

 plus minusve emarginato, costis intermediis saepe leviter suberosis. 



Small perennial herb. Stem creeping, rooting at the nodes, 

 sparsely branching. Petioles erect, slender, 1.5-9 cm. long, 

 sparsely and minutely hirsute; leaf -blades peltate, suborbicular 

 to oval, up to 2 cm. in diameter, shallowly and crenately about 

 8- to 10-lobed, glabrous. Peduncles about 1 cm. long, usually 

 bearing an apical cluster of 2-4 flowers with often 1 or 2 others
