COLEOPHORA. 



This is a new genus evidently belonging to Thymekacecs, which 

 I established a few years ago, upon some very singular floriferous 

 buds sent to me from Rio de Janeiro by my son, who found them 

 growing upon the trunk of a large and lofty tree in the dense 

 forest that covers the ascent of the Serra d'Estrella above 

 Iguassu, that being a continuation of the celebrated Orj 



an 



Mandioca 



to all botanical travellers as the residence of Baron Langsdorff. 

 Owing to the extreme height of the trunk, its branches were far 

 beyond reach, so that it was impossible to procure a single leaf- 

 bearing specimen. We can hardly imagine that the buds here 

 described form a distinct plant, parasitic upon the lofty tree 

 alluded to, as we have no instance of any such parasitism in 

 that f^imily ; on the contrary, it consists mostly of large trees, 

 and we may conclude from analogy, that these are floriferous 

 buds, emanating from the parent trunk : this is the more pro- 

 bable, from the structure of the involucrating bracts that consti- 

 tute the buds, which are imbricate upon one another, broad, con- 

 cave, 4-lobed, destitute of any midrib or nervure, and marked by 

 numerous parallel or radiating veins, somewhat like those seen 

 in the fronds of Adiantum ; from this, they would seem to par- 

 take more of the nature of involucrating bracts than of leaves. 

 The chief peculiarities in its floral structure are the long filiform 

 support of the ovarium, which is inclosed in a tubular petal oid 

 hypogynous neetarium, whence its generic name, from ko\€o<;, 

 vaginay and (l>op€0, fero. The only instance I can find of any
