 613. DECUMBENT BUTTERFLY-WEED 



ASCLEPIAS DECUMBENS L. 



Quite similar to the preceding, but with spreading stems and 

 opposite leaves. Rather common on the railroad embankments, 

 along with A. tuberosa. 



614. SWAMP MILKWEED 



ASCLEPIAS INCARNATA L. 



Rather common in wet places ; on shore near Long Point ; abund- 

 ant south of Outlet Bay, and on the shore in front of the As- 

 sembly grounds, near the depot, near Winfield's, along shore south- 

 west of the lake, and still farther on in an old field. In flower by 

 Scovell's cottage June 28. Some pods yet unopened October 24 on 

 the south shore. 



G15. BLUNT-LEAVED MILKWEED 



ASCLEPIAS AMPLEXICAULIS J. E. Smith 



Not common ; the only plants seen were a few forming a patch 

 near the turn of the road where it crosses the railroad track near 

 the thoroughfare. The plants grew in the light sand just at the 

 edge of the rise which forms the broad hill back of the ice-houses. 

 This plant is a lover of dry sands, and, in the great stretches of 

 sand in counties north of Marshall, was observed to be fairly abund- 

 ant. It is by far the earliest of the milkweeds to bloom, coming so 

 long before them that it has usually finished its year's work, and 

 its winged seeds are wrestling for their escape from the ripened 

 gaping pod by the time the others come into bloom. Going out of 

 bloom at the lake by June 13, 1901. 



616. POKE MILKWEED; TALL MILKWEED 



ASCLEPIAS EXALTATA (L.) Muhl. 



A slender, woodloving form ; one of the most attractive and 

 graceful of the milkweeds, with drooping heads of white or creamy 

 flowers. In flower near Overmyer's woods during the latter part 

 of June; also in the clump of woods along the east shore of Lost 

 Lake outlet. 



617. COMMON MILKWEED; SILKWEED 



ASCLEPIAS SYRIACA L. 



The most common and well known milkweed in the state ; found 

 everywhere in dry ground about the lake. Although so common it
