MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[VOL. 11 



sometimes with only three rows in the dorsal part and four rows in the ventral, 

 or with one cell less on the dorsal margin, 12 cells wide at the base (ten cells 

 when there are five segments) ; segments uniseriate, four or five cells long, the 

 lowest cell averaging 95 /x long, the tip cell 50 //. long, the walls uniformly thin. 

 Stem underleaves similar, the lamina four (rarely three) rows of cells high, the 

 cells of the six (or five) segments as in the leaf. Branch leaves and underleaves 

 with four segments and a lamina eight cells wide. Plants dioicous. Male inflores- 

 cense terminal on a long lateral branch, the bracts and bracteoles in six to ten 

 series, the bracts concave, bifid, the bracteoles smaller, bifid, plane. Female 

 inflorescence at the tip of a lateral branch, a very short ventral branch, or a 

 very short ventral branch from near the base of a leafy lateral branch, the bract 

 and bracteoles similar, in three or four series, broadly ovate, with several short 

 teeth and cilia at the apex, margins undulate, lobed and toothed. Perianth long, 

 cylindrical to fusiform, contracted and with three broad keels above, the mouth 

 crenulate. Sporophyte not seen. PI. 53. Fig. 6, a-f. 



Habitat: Over soil, wood, and other bryophytes in open woods and boggy 

 meadows.

Additional reports of the species from Patagonia — Tierra del Fuego include Arnell (1957), 

 Evans (1898), Gola (1923), Herzog (1942a, 1954, 1957, 1960), Kiihnemann (1949), Massalongo 

 (1885, 1927), Montagne (1945a, 1852), and Stephani (1900a, 1900b, 1901a, 1905, 1911). 



The species also occurs in New Zealand (s.l., J. Hooker, as J. tetradactyla, NY), and is 

 still another example of the Antarctic pattern of distribution. 



There was much confusion as to the identity of the earlier collections of both 

 T. tetradactyla and T. plumulosa, as is indicated in part by the synonymy under 

 those species. The names L. neesii and Jungermannia (Lepidozia) javanica are of 

 frequent occurrence in the early literature. It was recognized later that L. javanica 

 Montagne was identical with J. plumulosa. The plants labeled L. neesii from 

 South America which I have examined belong to T. tetradactyla or T. plumulosa 

 and I have seen no plants of L. neesii from this area. The species Telaranea neesii 

 (Lindenberg) Fulford is readily distinguished from both T. tetradactyla and 

 T. plumulosa in that in the underleaves the lamina is two rows of cells high, 

 the cuticle is conspicuously striolate, and the long cilia of the female bracts and 

 bracteoles and the perianth mouth have one or more short branches or spines.
