latis denticulatis coriaceis margine revolutis glandulis piliferis sparsis, racemis axillaribus 

 pubescentibus squamulosis, calyce glabra, corolla extus glabra intus pilosa. 



Hab. Conception. — Apparently a large shrub, and possibly the A. phyllireafolia of Persoon, but the 

 characters of that species are very vague, and its flowers appear to be axillary and not racemed.

Hab. Conception. — Two small specimens of this, scarcely more than an inch high, each with a single 

 small, terminal and pedunculated flower, will not enable us to satisfy ourselves whether the species be dis- 

 tinct or not from the European E. filiforme. It is probably the E. chilense of Bertero in Bull, des Sc. 

 Nat. 1830, p. Ill, but of which no description is given. — Belonging to the Gentianece is the " Cachen-La- 

 ffuen " of Chili, the Chironia chilensis, Willd. ( Cachen, Feuill. Chil. v. 2. t. 35), but which is a true Erytliract. 

 The calyx, corolla, and stamens, in our specimens from Mr. Menzies, and from Gouan's herbarium, follow the 

 quinary arrangement. The nearest to it, as Kunth remarks, is his E. quitensis, only differing by the parts 

 being in fours; but we do not consider that a distinct species. Though it be much used medicinally in Peru, 

 Humboldt never saw it wild there ; but it was cultivated in the plains of Chillo, the inhabitants of which may 

 have originally brought it with them from Chili, where it is undoubtedly a native. The circumstance of only 

 four stamens, instead of five, being observed in the Peruvian specimens, is not, we conceive, sufficiently 

 constant for a specific definition : we cannot, therefore, agree with Sprengel, who has, on that account, placed 

 it in Exacum, without attending to other more important characters. The Peruvian name, too, is a cor- 

 ruption of the Chilian one, which ought to be written as above, the word " Laguen " meaning merely a 

 plant ; while the particular name of the present one, in the Indian language, is " Cachen."
