480 Select Plants for Industrial Culture and 



Russula vesca, Fries. 



Europe. One of the best of mushrooms for the kitchen within 

 the genus Russula, which has representatives in most parts of the 

 globe. Dr. Cooke mentions further as culinary R. lepida (Fries), 

 R. virescens (Fries), and R. alutacea (Fries), the last-named also indi- 

 genous in the colony of Victoria. Professor Morren notes R. integra 

 (Fries) as used among the Belgian champignons. Under any circum- 

 stances, mushrooms should only be used when freshly collected or 

 quickly dried. 



Ruta graveolens, Linn6. 



The Rue. Mediterranean countries and the Orient. Hardy in 

 Norway to lat. 63 26'. The foliage of this acrid and odorous shrub, 

 simply dried, constitutes the rue-herb of medicine. The allied R. 

 sylvestris (Miller) is still more powerful in its effect. These plants 

 and others of the genus contain a peculiar volatile oil and a glycosid, 

 the rutin. Fresh they should be handled most cautiously, best with 

 gloves. 



Sabal Adansoni, Guernsent. 



Dwarf Palmetto. South-Carolina, Georgia and Florida. A stem- 

 less Fan-palm, jvith the following congeners, Rhaphidophylltim 

 Hystrix and Washingtonia filifera, attaining the most northerly 

 positions of any American palms. According to Count de Saporta it 

 resists a temperature as low as 17 F. Professor Ch. Naudin found 

 it to endure the frosts in Southern France to 43 20' north latitude. 

 This palm does well in marshy places. 



Sabal Palmetto, Loddiges. 



Extends from Florida to North- Carolina, 36 N.L. The stem 

 attains a height of 40 feet. This hardy palm delights on sandy 

 coast-tracts. Stems almost imperishable under water, not attacked 

 by the teredo, hence used locally for piles of wharfs and jetties 

 [G. Hoeck]. 



Sabal umbraculifera, Grisebach. 



West-Indies. Attains a height of 80 feet or occasionally even 

 over 100 feet. Though naturally a tropical Savannah-palm, it has 

 proved even hardier than the orange. A near relative is S. Black- 

 burniana (Glazebrook), a native of Bermuda, where, according to Sir 

 John Lefroy, it gains a stem height of 50 feet, and where the leaves 

 are extensively used for plat ; the sweet pulp of the fruit is edible. 

 At Hyeres this palm withstood a temperature of 22 F. [Bonnett]. 

 Another equally tall Antillan palm is S. glaucescens (Loddiges). 

 bear seeds freely.
