Fr very young but seems to be more contracted about the lateral ring and possibly will be simply (S.D) now smooth) [Note these chars. are also in S. tuberosum whose flo all ages are yellowish white] Root also thick bluntly as Costa ill for S. tuberosum. St very hispid with recurved bristles (at base almost prickling) and len upper part) with shorter stiff hairs mixed in. Less hispid but less severely so than at. Basal lo long stalked ovate to obovate lanceolate, broadest near base but slightly decurrent just at tip of pedicle too upper in grow progressively shorter pedicles more decurrent on pedicle until above the middle of the at, they are sessile and definitely this very nar- rowly decurrent.
