without obvious stipular margins, and with the fruits constricted at 
base or pyriform, is confined to saline mud of the Atlantic coast of the 
United States and of southwestern Nova Scotia. The second species 
L. carolinensis Coult. & Rose, a plant with long-petioled leaves having 
spatulate or oblong blades up to 2.5 em. long and 1.5 em. broad and 
comparatively large globose fruits, was originally described from the 
southeastern United States but it is apparently found also in Paraguay 
(for example, Hassler, no. 12,271) and elsewhere in temperate eastern 
South America. 
The third and most widely spread group of species is typified by L. 
attenuata (Hook. & Arn.) Fernald,! a plant characteristic of southern 
South America and the Andes and represented northward by L. 
occidentalis Coult. & Rose and L. Sehaffneriana (Schlecht.) Coult. 
& Rose and southward by the plants of the Falkland Islands, New 
Zealand, Tasmania and Australia which have erroneously passed as 
the Atlantic North American L. lineata or Crantzia lineata (Michx.) 
Nutt. The published illustrations? of fruits indicate considerable 
differences and it is possible that the austral series contains other 
species than L. attenuata and L. Schaffneriana but without better 
material than is now at hand it would be unwise to attempt further 
subdivision. The essential point in regard to the Australian, New 
Zealand, Tasmanian, Falkland, Argentine and Andean plants is, 
that they as well as the Mexican and Pacifie North American plants 
all differ in fundamental characters from the Atlantic North American 
L. lineata; for in them all the more elongate and slender or often 
attenuate leaves are tufted along the comparatively stout creeping 
stem, not solitary and scattered as in L. lineata; when well developed 
they show 6-13 joints instead of only 3-6 (rarely 7) and they often 
have scarious stipular margins which frequently persist as old shreds. 
Whether they finally prove to be a single species, L. attenuata, or 
several, the plants of Subantarctic regions and of temperate and 
Andean South America constitute, with the Mexican and Pacific 
North American plants, a distinct section of Lilaeopsis. 
It is thus evident that, although differing in details of distribution, 
Polystichum mohrioides, Myriophyllum elatinoides, the red-berried 
Empetrums and the species of Lilaeopsis centering about L. attenuata
