The discovery of the fruit of this plant near Oporto by Mr. Isaac
Newton in 1879, confirms the accuracy of its reference to the tropical C.
introflexus, the only difference we find being that in the European forms the
arista is straight, but in the southern it is generally reflexed at an angle
from the lamina ; the chief peculiarity of the species is seen in the male
plants, in which the leaves on the innovations are quite short and lax,
gradually becoming more elongated and crowded to the coma, and thus
strongly resembling a Polytrichum, e.g., P. pilifenm.

This species differs both in habit and areolation from all the others, the
upper cells having a distinct sigmoid curve, and the rough back of the leaf
near the apex must not be overlooked. The hoary point to the leaf is
very variable and sometimes is reduced to 2— 3 cells or may be quite
wanting.

as a section.
