LOCALITY OF THE NEW SPECIES OF ARCEUTHOBIUM. 405 
transmitted to Mr. Leggett of the Torrey Botanical Club of N. Y., 
where it was first brought to the notice of Dr. Torrey. Later in 
the season the same species was also found by Mr. Peck, in a 
peat marsh near Sand Lake in the vicinity of Albany, N.Y. Sub- 
sequently Mrs. Millington collected and transmitted numerous 
specimens in different stages of growth, from the original locality 
in Warren Co., N. Y., to Dr. Engelmann of St. Louis, who has 
been engaged for some time, in working up a monograph of the 
North American Species of Arceuthobium. 
For the benefit of future explorers of the botany of this northern 
district, I cannot do better than indicate the exact locality of this 
interesting plant as first pointed out by Mrs. Millington, viz. :— 
About two miles north of Warrensburg, Warren Co., N. Y., fol- 
lowing the plank road leading to Chester, you pass on the right 
hand (east) of the road, an extensive marshy track, which on pen- 
etrating a narrow belt of timber, opens up into a wide sphagnous 
swamp occupied with occasional clumps of Samarack, and bordered 
by low stunted growths of black spruce (Abies nigra). Here the. 
plant in question may be found without difficulty, the first indi- 
cation of its presence being observable in distorted branches 
showing at their extremity a massed growth of finely divided 
‘Spray, having a somewhat faded foliage. These masses will, on 
closer inspection, reveal the minute parasite, occupying the upper 
or thrifty growing branches. Of other points worthy of mention, 
I may note briefly. 
lst. The period of flowering (different from most other species 
of the genus) is in spring. At the time of my visit, May 1th, 
the male blossoms were fully opened and the pollen mostly shed ; 
the female flowers also well developed. 
/ 2d. As far as my observation goes, the plant is strictly diœ- 
fous, males and females occupying separate trees: not even 
occurring on different branches of the same tree. The male 
dae seem to be most frequent, though female plants are not 
eè, 
` 3d. The parasitic growth, whether male or female, seems to per- 
meton the same branch extending upwards, year by year on the 
= Y growing branches; leaving only the scars of previous- 
 Srowths on the lower portions of the limb; the distortion being 
_ “vidently due to this cause. 
4th. Neither male nor female plants persist beyond the pegiod
