IDENTIFICATION OF CATALPA. 1 OH 



seeds are usually shorter and always narrower than Sijeciosa. They are 

 Irom one to two inches in length and three-sixteenths to one-fourth inch 

 in width, there is less hair on the ends and it is more or less penciled or 

 drawn together. 



The seeds of the two species are quite different and are easily 

 recognized. 



To repeat, the principal marks of idenLificalion are shown by the 

 following comparative summary: 



SPECI05A. 



Tree, rather robust upright grower, with a dark deeply wrinkled bark. 



Blooms rather sparingly from middle until the last of June, small 

 clusters of large flowers. 



Seed pods are borne singly or in pairs, very seldom three or more 

 in a cluster. The pods are from twelve to twenty-two inches in length 

 and one-half to five-eighths of an inch in diameter. 



The seeds are both long and broad, one and three-fourths to two and 

 three-fourths inches in length and one-fourth to three-eighths inches 

 in breadth, with hair well distributed on both ends and not penciled. 



BIGNONIOIDES. 



Tree inclined to spreading growth, with lighter colored bark, much 

 inclined to scale off. 



Blooms the last of June and first of July, larger clusters of smaller 

 flowers. 



Seed pods are borne in clusters of two or six and more, and they are 

 usually shorter and always less in diameter than- Speciosa. 



The seeds are shorter and narrower than Speciosa with less hair on 

 rather pointed ends and more or less penciled. 



In considering the foregoing it must be remembered that I have 

 given general characteristics of the two species and refer particularly 

 to the extreme types, the two ends if you please of a long line of similar 

 individuals between the two extremes, which apparently gradually merges 

 from one to the other thus making difficult the identification of some 

 individual trees. There is quite a wide variation in the pods and seeds 

 of undoubted Speciosa. Please note the difference between the pods and 

 seeds of No. 1 (illustrating), which are long and heavy, borne singly and 

 in pairs, and No. 6, which are much shorter in seed and pods, the latter 

 being in clusters of two to six. This No. 6 is from the largest catalpa 

 tree in Fillmore county. It is twenty-six inches in diameter one foot 

 from the ground and nearly fifty feet in height. John P. Brown, of 

 Indiana, examined this tree several years ago and pronounced it Speciosa. 



Trees growing on creek bottom land produce much larger seed than 

 the same species grown on the upland and this has led to some confusion 

 in determining the Speciosa. 



This identification of catalpa is a comparatively easy matter as 

 between the extremes, but this merging or grading of the two species
