126 Select Plants for Industrial Culture and 



Coznbretum butyraceum, Caruel. 



The Butter-tree of Caffraria and other parts of South-Eastern 

 Africa. The Caffirs call the fatty substance, obtained from this 

 tree Chiquito. It is largely used by them as an admixture to their 

 food, and is also exported. It contains about one-quarter olein and 

 three-quarters margarin. This butter-like fat is extracted from 

 the fruit, and is of an aromatic flavor. The tree should be hardy 

 in the warmer and milder parts of extra-tropical countries. The 

 exact systemic position of this tree remains still obscure. 



Comptonia asplenifolia. Solander. 



The Sweet-Fern of North- America. This dwarf shrub is perhaps 

 quite worthy of dissemination on sterile hills, as the foliage contains 

 nearly 10 per cent, of tannin ; an extract of the leaves has come 

 into the tanning trade. The plant is also not without medicinal 

 value. 



Condalia microphylla, Cavanilles. 



The Piquillin. Chili and Argentina. A bush, yielding sweet, 

 edible, succulent fruit. 



Conium maculatum, Linne. 



The Poison-Hemlock. Europe, Northern Africa, Northern and 

 Western Asia. A biennial herb, important for medicinal purposes. 

 It should however not be allowed to stray from its plantations, as 

 it is apt to be confounded with culinary species of Anthriscus, 

 Chserophyllum and Myrrhis, and may thus cause, as a most 

 dangerous plant, disastrous mistakes. Active principles : coniin 

 in the fruit, also conhydrin. The wild or naturalized plant best 

 for therapeutic use. 



Conopodium denudatum, Koch. 



Western Europe. The small tuberous roots of this herb, when 

 boiled or roasted, are available for food, and known as Earth- 

 Chestnuts. The plant is allied to Carum Bulbocastanum. 



Conospermum Stcechadis, Endlicher. 



West-Australia. The question has arisen, whether this shrub? 

 with C. triplinervium (R. Brown), ought to be introduced into any 

 desert-country. All kinds of pasture-animals browse with avidity 

 on the long, tender and downy flower-stalks and spikes, without 

 touching the foliage, thus not destroying the plant by close crop- 

 ping. 



Convallaria majalis, Linne. 



Europe, Northern and Middle Asia to Japan. The " Lily of the 

 Valley." Far famed as a lovely fragrant spring-plant, desirable 

 for naturalisation in any temperate forest-regions ; quite a trade-
