species in its caulescent habit; it is of the same morphological type as the 

 rosulate dwarf trees of which there are so many in these islands. 



In spite of being unable to give a full description of this, peculiar plant, 

 I have thought it better to give it a name: it is certainly not identical with 

 any other, and I do not think it will have to be transferred to another genus, 

 if not to a new one.

 IX.366, reduced Ochagavia to Rhodo- 

 stachys. It is a matter of taste if we 

 follow him or not. Ochagavia was 

 described in Bot. Zeitung 1856, Rhodostachys in Linnaea 1857; the difference 

 between them is slight, the epigynous tube being more than twice as long in 

 the former, reaching a length of 12 — 15 mm. The stem is much more elongated, 

 clothed with leaves, the stamens shorter or as long as the petals, which are of 

 a deep violet-crimson. The inflorescence is a short compact spike. 

 Area of distribution: Endemic in Masatierra; monotypic.
