10 BOTANICAL BULLETIN. 



complete set of Dr. Gray's Grasses and Sedges. I was informed by Dr. Sloan, 

 President of the Xat. Jlist. Soe., that Dr. Clapp began his botanical investigations 

 when his eyesight liad about failed liiin and lie was compelled to do sometliing to 

 engage his attention and keep him in the open air as much as possible. If he had 

 been driven into the study of botany earlier in life lie might have established 'in 

 Xew Albany an exceedingly fine herbarium, for he bad obtained many good ex- 

 clianges, and was in correspondence with tlie most eminent botanists of liis daj-. 

 Among other exchanges were sets of plants from Louisiana and Ohio sent b}' Dr. 

 Riddell. The collection was bundled up at Dr. Clapp's death and the dust of many 

 years w^as allowed to collect upon it. It remained entirelj- undisturbed until 

 within a very few years and only now is it in complete order, with modern nom- 

 enclature and modern paper, ready for use. — Ed. 



Some plants out of their accredited range.— While in Wisconsin I noticed 

 some plants away from their accredited range. laopi/ruoi biternntum, T. & G. is 

 abundant in the northern part of Walworth Count}', where also Cassandra calycu- 

 lata, Don. is found in many of tlie tamarack swamps. Naprea dioica, L. has several 

 stations, to my knowledge, in Green County. On the track of the M. & St. P. R. 

 R., between Janesville and Hanover, in Rock Countj^ I found Cenchrus tribnloides. 

 L., Froelichia Floridana, Moquin and Cacalia suaveolens, L., the latter growing 

 abundantly near the Junction depot at Hanover, far from "rich woods." — Herbert 

 E. CoPELAND, Indianapolis, Ind. 



OENOTHERA SPECIOSA.— This plant is abundant from Jackson County, Missouri, 

 soutliward, but is not found east. It generally prefers a rich limestone soil of but 

 a few inclies thickness resting on limestone. When in full bloom its corolla is 

 often over three inclies across, and a bed of these plants, a half acre or more in 

 lixtent, with their pure white flowers, is very beautiful.— G. C. Broadhead. 



On the size of forest trees in Jefferson County, Ind. — During the sum- 

 mer of 1873, in the prosecution of some botanical work in Southern Indiana, I was 

 led to observe the size and character of the forest trees by the numerous questions 

 asked me on the subject by the farmers in the region worked up. I here present a 

 (condensed view of the results obtained by the measurement of over 1000 trees in 

 Jefferson County. The measure of the diameter was taken three feet above the 

 ground. The numerals in brackets following the name indicate the number of 

 trees measured.

The largest tree found in the county (Platanus occidentalis, L.) measured at the 

 base 13 feet-6 inches Some 10 feet up the trunk the diameter was 8fect-4 inches, and 

 25 feet from the ground measured 6 feet. The height of this giant tree could not 

 be ascertained, as it had been broken by storms. Fagus ferruginea. Ait. and Lirio- 

 dendron Tulipifera, L. attain a size at times I have not seen equalled in any other 

 part of the state. I have noted several of the latter species between 8 and 10 

 feet in diameter. Of the former a diameter of 5 feet is not uncommon, and I have 

 two noted that exceed 6 feet. Some few items concerning the numerical relation 

 which the different species bear to one another, will be reserved for subsequent 

 notes. — M.S. Covl.te-r, Logansport, Ind.
