Jun 22d 1879— The arching of the Hypocotyl, is not in the lest least due to geotropism, at least in Cucurbita ovifera. — for when seed pinned through cotyledons within seed horizontally to cork & kept in darkness over water, or in water, the base upper part of radicle radicle or base of hypocotyl is lifted up in opposition to geotropism, & the arch formed in usual manner — it is due to epinasty— (Though as we know apogeotropism soon soon comes into play & raises both sides of arch arch into vertical position. N.B The closure or arching of the a many hypocotyls of many seeds pinned in various positions on the cork, was in opposition to geotropism, & must be due to epinasty, for light was excluded.
