110 Select Plants for Industrial Culture and 



States it is a favorite tree for shade-lines. When closely planted it 

 will grow tall and straight, with a stem fully 50 feet to the first 

 branch. It prefers bottom-lands, but will succeed in almost any soil 

 and position, according to Mr. Barney. It is hardier than most 

 Eucalypts, but will not stand severe frosts. According to Professor 

 Burrill, it is not liable to be destroyed by insects ; bears seeds when 

 quite young. Professor Meehan considers the wood to be as durable 

 as that of the best Chestnut-trees ; indeed it lasts for an almost in- 

 definite period. General Harrison insists, that there is nothing like it 

 for posts. Catalpa-pickets of the old French stockade are still sound. 

 Logs thrown across water-courses for crossing have lasted for three 

 generations ; railway-posts and platforms of this wood are almost 

 indestructible. Logs a century old, and posts half a century old, 

 were not in the least decayed [Barney]. Railway cross-ties made of 

 this wood are also very durable, a tree twenty years old furnishing 

 sufficient timber for four ties. Canoes of Catalpa-wood never crack 

 or decay. 



Catalpa Kaempferi, Siebold and Zuccarini. 



Japan. Grows in eight years to about 25 feet in height, with a 

 trunk of 2 feet circumference ; bunches of flowers very large and 

 fragrant [Ho vey]. Proved hardy at Christiania [Schuebeler]. C. 

 Bungei (Meyer) from North-China, or a closely allied species, can be 

 grown for hedges. Flowers of all Catalpas sought by bees. 



Catalpa speciosa, Warder. 



In the Mississippi-States. Hardier and taller than C. bignoni- 

 oides; blooming earlier; leaves inodorous, flowers larger, growth as 

 rapid and wood as durable; also only with a very thin layer of 

 destructible sapwood [Dr. Engelmann]. Found to have attained in 

 40 years a stem-circumference of 40 feet at 4 feet from the ground 

 [Letterman] . 



Oatha edulis, Forskael. 



Arabia and Eastern Africa. The leaves of this shrub, under the 

 designation of Kafta or Cath, are used for a tea of a very stimu- 

 lating effect, to some extent to be compared to that of Erythroxylon 

 Coca. To us the plant would be mainly valuable for medicinal 

 purposes. 



Caulanthus procerus, Watson. 



California. A stout biennial. Locally used as a substitute for 

 cabbage [Brewer], but here only mentioned as likely capable of 

 cultural amelioration.
