is somewhat like a very tiny Equisetum except no teeth at nodes as in Equisetum. Spherical orange-colored bodies found among whorls are probably eggs, not seeds [not like Hippuris] found 8-26-29 [8-31-29 Highland Brooks above Highland Pond. Entirely like ill. in Coutler p.46. St about 6 in long. Inter- nodes) in long towards base to ½ in, or less towards Tip. Nodes toward base sometimes enlarged with conspicuous whitish growth, the whorls of branches at this point not well developed. In upper branches, ovoid spore cases consisting of greenish outer covering & inside it a hard black case spirally marked. Spore case 1¼ mm high, sessile, subtended by 2 small branchlets. Spore case seems later to become soft whitish, perhaps passing thru the yellow form noted 8-19-29 [when thought to be eggs of some insect & not related to this plant] and frequently found 8-31-29 (In some cases these orange bodies seem to be more globules & without spiral mark- ings of spore cases) Query: have the small flat, orange-colored radiate bodies any sig. nificance? Plant has unpleasant fondish odor tho taken from clear running water at edge of brook.
