188 JUNGERMANNIACEAE 
—though apparently always autoicous—occasionally show an 
antheridial spike at the end of a lateral branch, and we have ob- 
served the same conditions in certainly autoicous plants of С. & К. 
Hep. Eur. 282. 
Lepidozia filamentosa У (Lehm. & Lindenb.) Lindenb.—a very 
distinct species, now certainly known only from Alaska—will prob- 
ably yet be found to extend farther down the coast, though we are 
inclined to doubt its occurrence within the limits of California. 
This species is larger in all its parts + than Дер оса reptans and 
more rigid and brittle in drying. Тһе main stems аге 2-3 ст. 
long and .36-.65 mm. in thickness. The leaves are almost trans- 
versely inserted and erecto-patent to suberect ; the underleaves are 
proportionally larger than in Z. reptans, being 2—4 the size of the 
lateral leaves; the fronds have therefore the appearance of being 
almost uniformly developed on all sides instead of being distinctly 
dorso-ventrally flattened. Fig. 4 in Lindenb. & Gottsche's plates 
scarcely does justice to the similarity in size of the leaves and under- 
leaves ; and Taylor's “ stipulis minutis ” of **Zegidosia attenuata” 8 
difficult to understand in view of the undoubtedly authentic original 
specimen existing in his herbarium, which is an exact counterpart of 
the original of Jungermannia filamentosa, now preserved in the Nat- 
ural History Museum of Vienna. In the original of Г. filamentosa 
the perianths are 4-6 mm. long and are widest at the middle or? 
little above; the only capsule seen is 2 mm. long. Menzies wa 
probably the first collector, though his name is not cited by Linden 
berg and does not appear on the Vienna specimen. The speci® 
has since been collected, so far as we know, but twice: by J.M 
Macoun, Prince of Wales Sound, Alaska, September, 29, oi! 
(no. 389, associated with Scapania Bolanderi, in herb. Underwood), 
and by Miss Jessie Trowbridge, Sumdum, Alaska, 1895 (in herb. 
Howe). The species is apparently dioicous. We have seen perm 
anths only upon the original specimen. The androecia are р 
ventral branches. The main stems and lateral branches (especially
