Chiloscyphus amphibolius, Nees ab E., gathered in Brazil by Dr. Von Martius, is a smaller species, and has 
leaves of a thinner texture than any of the specimens here referred to the Plagiochila chiloscyphoidea of Lindenberg, 
. a plant which possesses all the characters attributed to Leioscyphus, having the habit of Zophocolea or Chiloscyphus, 
and the perianth of Plagiochila. Besides the three species which Dr. Taylor made of this plant, it composed part 
of his Lophocolea pallide-virens, probably all that part regarded by him as “(status minor) omnino fuscati,” for the 
specimens are all of a brown colour, not observable in the Lophocolea itself. The bulk of the specimens of Lopho- 
colea multipenna undoubtedly belong to the present species; but creeping over it in very small quantity is a per- 
fectly distinct species of Lophocolea, which seems to have furnished part of the characters designating L. multipenna, 
particularly the triquetrous perianth ; but the form of the leaves, “ obovatis ” and “ ovato-oblonga,” relates alone to 
a rather smaller than usual state of Leioscyphus chiloscyphoideus, and specimens exactly similar were gathered at 
Cape Horn. To this genus belongs Z. equatus, Flor. Antarct. p. 433. t. 158. f. 3, L. strongylophyllus, l. c. t. 62. f. 9, 
L. reclinans, 1. c. t. 159. f. 1, of which the perfect perianth is nearly three times longer than broad, compressed, 
the mouth truncate and smooth; about half an imperfect perianth is represented in the figure 4. In L. (urgescens, 
Le. t. 64. f. 2, the perianth is compressed, the mouth wide, and the lips smooth; but it presents slight indications 
of being formed of three parts, namely the two uppermost leaves and amphigastrium, for there are often two notches 
in the mouth, just where the line of union must be supposed to be.
