The plants and the insects associated with them were observed at 

 several places in New Jersey, but the principal observations were 

 made at Arlington and in a nursery at Rutherford. It must be un- 

 derstood that the dates given apply to the latitude of New Jersey and 

 would probably be somewhat different for the same species at points 

 further south. 



The swamp rose-mallow is a perennial herb growing from three 

 to six feet or more in height and forming a number of erect, cane- 

 like stems at the summits of which are borne the conspicuous flowers 

 on stout pedicels. The flowers vary from four to seven inches across, 

 are white or pink, sometimes with a crimson center and form a con- 

 spicuous feature of the marsh inhabited by these plants when in 

 bloom from late July to early September. " Only one style of flower 

 occurs on any given plant, but the plants are usually mixed together 

 indiscriminately and show besides differently colored flowers, con- 

 siderable difference in the shape of the leaves, pods and calyx lobes. 

 Dr. N. L. Britton has described as distinct H. oculiroseus (cf. Jour. 

 'N. Y. Bot. Gar., IV, 220, 1903) from a plant of the crimson eye, cul- 

 tivated and introduced into the nursery trade by Mr. William Bassett 

 of Hammonton, N. J., from an original plant obtained at Absecon, 

 N. J. The wild plants now growing there, however, are normal H. 

 moschcutos and I regard Dr. Britton's species as a sport due to culti- 

 vation " (Witmer Stone, Plants of Southern New Jersey, N. J. State 

 Mus. Rept., 1911). 



The conspicuous flower is followed by a fruit in the form of a 

 5-valved, green capsule almost an inch in diameter, ovoid and more 

 or less acuminate at apex. This contains a number of round or reni- 

 form brown seeds, which fall or are shaken out after the capsule 

 splits open in October. The swamp rose-mallow occurs along the 

 Atlantic Seaboard from Massachusetts to Florida chiefly in the 

 brackish marshes, but also to some extent in marshes bordering 

 fresh water ponds and streams. In New Jersey this species is found 

 in numerous places along the coast and Delaware River. It occurs 

 at several inland points as well, such as Lawrence Station (Mercer 

 County) and Railway (Union County), while the most northern 

 points recorded are near Closter (Bergen County) and Hopewell 

 (Hunterdon County). Frequently it is found growing among cat- 

 tails. An interesting feature of this plant is that while its natural
