Additional Notes. 
Six years have elapsed since the Trees of Indiana was published. 
During this interval the author has spent four seasons in the field 
making a study of the distribution of the flowering plants of Indiana. 
Special attention has been given to the trees. In making this study 
a distance of over 18,000 miles was traveled by automobile. Every 
county was visited and those counties which gave special promise of 
yielding data of botanic interest were given particular attention. 
This study has resulted in additional information concerning our 
trees as indicated in the following notes: 
Pinus Strobus Linneus. Wuite Pine. This species was formerly 
abundant along the bluffs of Bear Creek, near Fountain in Fountain 
County. Trees thirty inches in diameter were frequent. 
Tsuga canadensis (Linnzeus) Carrier. Hrmiock. Additional loca- 
tions for this species are the bluffs of Guthrie Creek in Jackson County 
and of Back Creek near Leesville in Lawrence County, and a steep 
hillside and bluff one mile north of Borden in Clark County. 
Taxodium distichum (Linnzeus) Richard. Cypress. <A few trees 
still exist along Cypress Creek just east of Newburg in Warrick 
County. This is the eastern known limit of this species in Indiana. 
Hicoria. Several species of this genus are not well understood. 
The author has given this genus special study during the past three 
years. Duplicates of all material collected were sent to C.S. Sargent, 
who has recently revised the genus. He distinguishes several varieties 
that occur in Indiana which are not given here. Dr. Sargent believes 
the form referred to Hicoria glabra var. odorata, on page 71 should 
be regarded as an extreme form of Hicoria alba. 
Hicoria Pecan (Marshall) Britton. Prcan. In the Indiana Geo- 
logical Survey, Vol. 2, page 288, J. M. Coulter reports this species 
from Jefferson County. He adds the following: “There are but two 
specimens of this tree found in the county; of these, one was planted 
and the other is probably native.”’ 
A colony of Swiss settled in the vicinity of Vevay, which was their 
headquarters. They early learned the value of this nut-bearing tree 
and freely planted it. Today several large trees are found in the 
yards of Vevay, and a few miles east of Vevay is the remnant of a 
erove of several acres which was planted in rows. The oldest inhab-
