88 List of the Plants of Chile. 



Isatis tinctoria. L. Common in drakis, near Rancagua, and in 

 cultivated situations. It is probable that some persons may have 

 been desirous of trying its cultivation, to extract the blue which 

 might be used as a substitute for the indigo of commerce. This is 

 what is called in French Indigo-pastel. It might be well to culti- 

 vate it extensively. 



Juglans regia. L. An European tree, known by the name of 

 nogal. Every body knows the nut and the different uses to which 

 it can be applied ; it is, therefore, useless to enter into details. 

 Although the walnut is common in this country, it might be usefully 

 multiplied, with a view both to the increase of its fruit and the abun- 

 dance of an excellent wood. 



Juncus. L. Three species, which approach the J. acutiflorus, 

 Ehrh. Bvfonius and bulbosus, L. They grow in drains and humid 

 meadows, in the plain. 



Jvngermannia. L. Plants of the hepatic family, which delight 

 in shady and humid places. The J. Tamarisci, L. grows on the 

 mountain rocks ; the Magellanica, Lamk. on the trunks of trees : 

 it is scarce. There is another species, which I believe new, and 

 which grows in elevated fields, on the highlands. 



Jussieua. L. A species of this genus is very frequent in marshy 

 situations and in drains. It approaches the J. repens, L. and dif- 

 fers from it in being velvety, which however is not constant. The 

 J. Monievidensis, Spr, is not very different from our plant, as I have 

 often seen the peduncles armed with two bracts. I also think that 

 the Onosuris Chamissonis, DC. prodr. belongs to this species, which 

 should not be separated from the genus Jussieua. 



Kageneckia ohlonga. Ruiz and Pavon. A very beautiful tree, 

 called bollen. It grows in the woods, on the highlands, and on the 

 heights near Cachapual. Its bark is used as a dye ; it is also thought 

 to be purgative, but is not at present employed. I have observed 

 that the young branches and leaves are glutinous, which induces me 

 to think that this species is only a variety of the K. glutinosa, Kunth. 



Kceleria villosa. DC. A very common grass in the dry pastures 

 of the highlands, and along the sides of roads in the plain. 



Krigia. Schreb. A small plant of the tribe of the Chicoracea, 

 frequent in high meadows, and in the plain. The generic character 

 answers to it, with some little difference, but among the species de- 

 scribed I do not find one with pinnate leaves. I shall call it K. 

 Chilensis.
