1. Catalpa bignonioides. Walt. 



Leaves ovate, heart-shaped at the base, pointed, and rarely 

 somewhat lobed. Flowers white, tinged with purple and dot- 

 ted with purple and yellow in throat; appearing (at the North) 

 from the 1st to the middle of July. Pods nearly cylindrical, 

 or often somewhat flattened, rarely ever one foot in length. 

 Seeds H inches long, their wings gradually narrowed to sharp 

 points, and ending in tufts of long, white hairs, often an inch 

 in length. Bark thin, scaly, silver gray. 



2. TUP: "EARLY FLOWERING" CATALPA. 



This can be distinguished from Xo. 1 by its more gradually 

 pointed leaves, its larger white flowers, appearing (in Ohio) 

 during the first week of .June; by its larger and much flatten- 

 ed pods, often 1H to 18 inches long, and with much thicker 

 walls; by its shorter, broader seeds, with wings of equal 

 width to their rounded ends, which arc terminated by a .copi- 

 ous fringe of stouter hairs; and by its darker and thicker, fur- 

 rowed bark. 



I have already shown that the wood of this form is consider- 

 ably heavier than that of the ordinary catalpa. Further in- 

 vestigation is necessary to determine whether this is a dis- 

 tinct species, or only a well-marked form of Catalpa bicfnonioide*, 

 and connected with it by intermediate forms. If distinct it 

 should be known as C. speciosa. 



'>. C. Kaempheri, I). C. Native of Japan. 



Leaves smaller than in the American species, ovate, heart- 

 shaped at the base, abruptly sharp-pointed and often with one 

 or more sharp-pointed lateral lobes. Flowers smaller than in 

 the American species, spotted with purple, sweet-scented, ap- 

 pearing (near Boston) during the first week of . July. Pods 

 about one foot long, cylindrical, slender, not more than ^ of 

 an inch in diameter. Seeds much smaller than in the- Ameri- 

 can species, the wings short, blunt, and ending in a copious 

 fringe of soft white hairs; the seed and its appendages rarely 

 Y of an inch long. Bark in young plants thin, scaly, light 

 gray. 



F have no information of the si/e this tree may attain un- 

 der favorable conditions, although it is spoken of as a small 

 tree in all works on Japanese botany. Near Boston it is rather 

 hardier than the American species, and flowers and ripens its 

 fruit freelv when not more than twelve feet high. T have no 

 information whatever as to the economic value of this species.
