Note 170 — Chapter I
Reading edition
No. 701 of Schomburgh, coll. 1, is wild in Guiana. According to Choisy, it is a variety of the Batatas edulis; according to Bentham (Hook, Jour. Bot., v. p. 352), of the Batatas paniculata. My specimen, which is rather imperfect, seems to me to be different from both.
