“…Later, new hyphal branches penetrate the body of the prey. Among these predacious species are included Trichothecium, Arthrobotrys, Dactylaria, Monacrosporium and Dactylella, all figured by Drechsler (1934a). Still others may be expected to turn up.…”

Carnivorous Plants details of structure. They are unicellular hairs with the bases embedded in a raised mass of epidermis and underlying parenchyma. They taper from the base gradually to the sharp tip, and the cuticle is raised to form folds or ridges, beginning at or near the base and converging on the apex, where they gradually fade away. These ridges are more pronounced on the hairs of the conductive surface, and are much weaker to scarcely distinct on the hairs of the detentive surface. rapidly, o.oi gram of fibrin being completely digested in 1.3 cc. of fluid in 2 hours.In the part with acid added "partial solution was noted at the end of 9 days, complete solution at the end of 50 days." S. minor. -Experiments were done in the field. No digestion occurred in 30 days (trikresol present) in the absence of acid or alkali, but it did occur when either acid or alkali was added to the fluid, but less vigorously in the alkaline, than in the acid medium. This species therefore stands in contrast to the others aforementioned. S. psittacina. -Field observation showed that fluid was being secreted in the pitchers, but in such small amounts that it had to be collected by dilution with water (0.5 cc. in each of 50 pitchers free of insects).The results were inconclusive, but indicated that a protease is present which is active in the presence of acid. Sarracenia purpurea. -The secretion in this species is very small in amount, being found as beads of moisture on the walls. Experiments were done by flushing the pitchers, emptying, and adding 10 to 15 cc. of water to each pitcher. After some days this was removed and tested. The fluid thus obtained showed an ability when alkaline to digest fibrin to a marked extent in 8, 24, 72, and 87 hours (4 samples), and completely in 42, 48, 120, and 135 hours, respectively. Three other experiments gave positive results in 42 and 87 hours.In acid, the results were equivocal. Sarracenia
