TWO KEW BATEACHIA. ^5 



little or not at a^l 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 Aloitis corolla makes 

 at its perfection. 



Two New Batrachia. 



Batraohium Bakbei. Annual in Oalifornian 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 withdrawn from water, the uppermost (perhaps also submersed) 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 13 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, 0. F. Baker, distributed under n. 786. 

 Habitat like that of A. Lobbii, and strongly marked by a most 

 peculiar and strikingly usneoid foliage. 



Bateachium pedunculabe. Stout and low annual, spread- 

 ing beneath the water iu slow streams of the Oalifornian Coast
