EuosMOLEJEUNEA DURIUSCULA 137 
Type-locality, Surinam (Curie). 
On trees or rotten logs, often growing with mosses or other 
hepatics. Florida (J. D. Smith, Farlow, Underwood) ; Alabama 
(Sullivant, Mohr); Mississippi (Langlois, Lloyd and Tracy); Louisi- 
ana (Drummond, Featherman, Langlois, Faxon). The species has 
a wide distribution in tropical America. 
Exsic.: Musc. Amer. St. Merid. 171 f. p. (as Jungermannia ` 
serpyllifolia). Musc. Alleg. 273 (as Lejeunea serpyllifolia var.). 
Hep. Bor.-Amer. 96 (as Lejeunea Sullivantiae). Hep. Amer. 135 
(as Lejeunea (Eu-Lej.) Underwoodit). 
Lejeunea Sullivantiae Aust. has been more or less of a puzzle 
to hepaticologists, and yet the original description, although brief, 
is not misleading. The specimens distributed by Austin and by 
Sullivant, moreover, are both abundant and characteristic. Un- 
fortunately Austin makes no note in his description of the female 
flowers, although they are fairly abundant in the material which he 
studied. The probability is that he overlooked them because they 
had developed no perianths. 
A few years after Z. Sullivantiae was published, Lindberg 
studied the specimens in Musc. Alleg. 273 and Hep. Bor.-Amer. 
96 and proved that they were identical with the dark tufts in No. 
171 of Drummond's exsiccata. He also stated that they could 
not be distinguished from Z. ¢hymifolia Nees, ? y of the Synopsis 
Hepaticarum,* a plant which he knew from male specimens col- 
lected in French Guiana by Leprieur. Z. thymifolia has since 
been reduced to Z. fava Swartz,t and the questionable variety 7 
is referred by Stephani to L. duriuscula, a species with which 
Lindberg was apparently unfamiliar Objecting to the name “ Z. 
Sullivantiae”” on account of the older Z. Sullivantii Gottsche,$ 
Lindberg gave to Austin's species the name Z. Austini, and pre- 
sumably referred to it the var. 7, to which allusion has just been 
made.

mens of var. y were collected by Beyrich in Brazil and are the plants mentioned in the 
Synopsis. Gottsche (Mex. Leverm. 218. 1863) refers these same speci imens to Z.
