TWO NEW BATRACHIA. 95 
little or not at all accrescent over the growing ovary, its teeth 
hardly more than acute. 
Borders of woods about Knoxville, Tenn., A. Ruth, October, 
1898. Just this plant is figured in the Botanical Magazine at 
t. 3496, where the reader of the text accompanying the plate 
will at first read it as if the representation were that of a plant 
from New York; and this is true partly, but only as to the un- 
colored dissections of a flower occupying the base of the plate. 
At the end Sir William informs us that the drawing of the 
main figure was by Dr. Short, whose type must naturally have 
been this southern species, as indeed, it shows for itself on a 
comparison with specimens. In this plate, also, may be seen 
just what approach to expansion the A/oitis corolla makes 
at its perfection. 
Two New Batrachia. 
BATRACHIUM BAKERI. Annual in Californian ponds and 
_ pools that go dry in summer: stems a foot long or more, nearly 
naked below, the lower nodes remote, marked by a solitary sim- 
ple lance-linear leaf or phyllode; proper foliage rather sparse 
and small, the submersed leaves with short narrow-linear widely 
divergent on almost divaricate segments not collapsing when 
withdrawn from water, the uppermost (perhaps also submersed) 
with truly filiform or capillary segments, these also rather firm, 
hardly collapsing ; stipules of the uppermost broad, appressed- 
pubescent: flowers very small: carpels 12 to 20 in a depressed- 
globose head: styles linear but short. 
Pools among the hills of the Coast Range near Stanford 
University, 8 May, 1902, C. F. Baker, distributed under n. 786, 
Habitat likethat of A. Zodd:, and strongly marked bya most 
peculiar and strikingly usneoid foliage. 
BATRACHIUM PEDUNOULARE. Stout and low annual, spread-
