16 Oephalozia. 



terete and is trigonous only at tlie pluriciliate apes. The dichotomous 

 ramification, Tvitliout a single postical branch, and the constantly 

 terminal $ flowers, separate it from CepJiaJozia, and assimilate it j)ro tanto 

 to Pleuroclada. I introduce it here, however, for the sake of comparing 

 it with a small group, almost equally related to Cephalozia, Micro-Lepi- 

 dozia, and Blepliarostoma. 



These are minute plants, with threadlike entangled stems, branched 

 only from the underside, and woven into broad thin films very like a 

 spider's web : hence my name for them, Aeachniopsis. The blueish-or- 

 whitish-grey colour makes the resemblance more striking. One species 

 I found lining the roof of a cavern in the Peruvian Andes, and, until 

 closely looked at, easily mistaken for the work of a s^^ider. The leaves 

 are capillary, consisting of only a single series of cells (which are 2 — 6 

 times as long as broad), and they are either single or twin. In the 

 species with bicrural leaves, the crura are separate to the very base, 

 where they are merely contiguous, but not connate, one leg or filament 

 being inserted slightly lower than, and partly in front of, the other, so ' 

 that the leaves are to be accounted succnbous. Underleaves none, or 

 reduced to two collateral unicellular papillae. The cladogenous tristi- 

 chous-leaved involucres are essentially of the same type as those of 

 Cephalozia, but more finely and numerously divided ; and so are the 

 trigonous perianths, but excessively elongate — 5 or 6 times as long as 

 broad — and ending in 12 capillary laciniffi. Male flowers monandrous. 



Although well and easily distinguished from Blepharostoma, these 

 Xolants so resemble it outwardly that I think it probable one or more of 

 the species may have been included in lists of tropical Hepatic^ under 

 the name " Jung, trichojohylla." They are in reality more closely related 

 to Micro-Lepidozia chcctophylla n. sp. — a plant I found in some abundance 

 on decayed wood in the forests of the xlmazon and Eastern Andes. The 

 latter has, however, all the leafy branches lateral, and only the peri- 

 chsetia are postical : normal features in all Lepidozm. The stem-leaves 

 are tripartite, with the capillary crura connate at the base, and there are 

 (as in every other Lepidozia) similar, but smaller underleaves. — Jung, 

 nematodes Gottsche in "Wright's 'Hep. Cubenses' stands so near to this 

 as to be barely distinguishable as a species. [There is a prior Lepidozia 

 nemmdes Tayl., from St. Helena, distinct from the Cuban plant, but 

 belonging to the same subgenus. Jung, conferroides G., another of
