time the stigmas are well developed, but not sufficiently glutinous to hold 

 pollen. The anthers are exceedingly small, and show no signs of 

 dehiscence undl about two weeks after the sngmas are dry, at which 

 time the pollen is shrunken, and apparently lifeless. If the grains 

 examined contamed fluid, it escaped detection. PVequent observations 

 of the ijlant in its habitat were made, as well as a close study of its 

 essential parts under the microscope. 



The foregoing facts seem to lead to but one conclusion, namely, 

 that the plant is a hybrid.— E. C. Howe, Yonkers, N. V. 



Carnivorous Plants. III.— Experiment No. 6.- Placed upon 

 a leaf, which had had the sunlight during the morning, a larva (same 

 as in No. 5), at 2 p. m., June 6, '79. 

 20 min. the submaruinal t. nearest the specimen had approached 

 and touched it; the marginal t. on one side had moved 

 through an angle of 45°. 

 80 " continued movement of those t. nearest the larva, many 

 being closed upon it; no further change was perceptible in 

 the marginal t. 

 112 " the submarginal t. opposite those mendoned before, have 

 moved considerably; movement among the disk t. perceptible. 

 3 hrs. no change from the last. 

 20 " considerable movement among all the t ; the submarginal 

 mostly closed upon ti.e specimen ; all but about 6 or 8 of 

 the marginal bent over toward the object. 

 22 " about the same as the last. 



29 " all the submarKinal. the edge of the leaf nearest the speci- 

 men, and some of the marginal t. mu'ch inflected. 

 67 " no change. 



73 " a slight i-fflex action is noticeable. 

 94 " the marginal and submarginal t. were wholly reflexed; disk 



t. partly so. 

 109 " completely reflexed. 

 126 " leaf with secretion on the t.; perfectly natural. 



Experiment No. 7. -Placed upon a leaf, which had had sun- 

 light during the forenoon, a minute piece of wood at 2 p. m.. Tune 

 6, '80. •' 



20 min. 10 or 12 of the submarginal t. were inflected, and three or 



4 of these touched the specimen. 

 80 " some further movement of the submarginal t. on one side; 



elsewhere no perceptible change; a few t. situated on the 



petiole had moved somewhat. 

 112 " the submarginal and disk t, had moved but little from the 



last. 

 3 hrs. no change from the last. 

 20 " no perceptible change. 

 29 " an apparent reflex action, although slight. 

 69 " all the t. were reflexed. 

 84 " leaf with secretion on the t.; perfecdy natural.
