932 REPORT OF STATE GEOLOGIST. 



TECOMA Juss. 



T. radicans (L.) DC. Trumpet-flower. Trumpet-creeper. 



In all parts of the State, in especial abundance and develop- 

 ment southward. It grows either in moist, rich, alluvial soils or 

 in sandy soils, being found as a constituent of the flora of the 

 Basswood dunes. When brought in cultivation it multiplies with 

 extreme rapidity. One of the most attractive of our climbing 

 plants. 



Flowers from June until August. 



Cass (Hessler); Daviess (Clements); Dearborn. (Collins); Put- 

 nam (MacDougal); Clark (Baird and Taylor); Franklin 

 (Meyncke); Jefferson (J. M. Coulter); Gibson and Posey 

 (Schneck); Jay, Delaware, Randolph, and Wayne (Phinney); De- 

 catur and Shelby (Ballard); Lake and Porter (Cowles); Vigo 

 (Blatchley); Hamilton and Marion (Wilson). 



CAT ALP A Scop. 



C. Catalpa (L.) Karst. Catalpa. Indian Bean. 



(C. bignonioides Walt.) 



This southern form has escaped from cultivation in the south- 

 ern counties of the State and is there well established. The wood 

 is light and weak, but very durable in contact with the soil, 

 making it valuable for posts. 



Flowers in June and July. 



Jefferson (Barnes); Clark (Baird and Taylor); Dearborn (Col- 

 lins); Franklin. (Meyncke); Gibson and Posey (Schneck). 



C. speciosa Warder. Catalpa. Larger Indian Bean. 



This is the species under cultivation in most parts of the State, 

 being largely used for ornamental and shade purposes. It has 

 escaped to a greater or less extent in almost every section in 

 which it has been largely cultivated. In some counties "catalpa 

 groves" have established themselves in rather damp, rich soils. 

 The wood is somewhat lighter in weight than in the preceding 

 species, but equally durable in contact with the soil. The rapid- 

 ity of growth of the catalpa suggests as suitable for planting for 

 "posts" and other purposes in which durability in contact with 

 the soil is desired. 



Flowers in May and June. 



Jay, Delaware, Randolph, and Wayne (Phinney); Vigo 

 (Blatchley); Tippecanoe (Coulter).
