Figure 1. Jaltomata incahuasina. Flowers are protogynous: the pistillate phase is shown on the left (anthers undehsiced) and on the right the hermaphroditic phase is shown (stamens have elongated and anthers dehisced). As shown in this photo, we observed gland-tipped finger hairs in department Piura, Peru (Mione et al. 809, photo by Segundo Leiva G.).
Figure 2. Flowers are protogynous: the pistillate phase is shown on the left (anthers undehsiced) and on the right the hermaphroditic phase is shown (stamens have elongated and anthers dehisced; photo by Segundo Leiva G.).

Figure 4. A pair of unripe fruits and a flower in pistillate phase are highest in this photo; a pair of flowers, one pistillate the other in its hermaphroditic phase are slightly lower. The larger leaf on left has its underside showing; other leaves are adaxial face up
(smallest units on ruler along bottom are mm, Mione et al. 809, Peru Department Piura, photo by Thomas Mione).
Figure 5. Jaltomata incahuasina. We observed gland-tipped finger hairs on this species in department Piura, as shown in the above photo (numbered units on ruler are cm; smallest units on ruler are mm, Mione et al. 809, photo by Thomas Mione).
Figure 6. Jaltomata incahuasina. Protogyny is evident: this flower is open but anthers have not yet dehisced; a day or two from now this flower would look like the one shown on the right in figure 7 (photo by Segundo Leiva G.).
Figure 7. Jaltomata incahuasina. The corolla and androecium have dropped off of the flower on the left; this occurs after a flower has been functional / open for days. On the flower on the left the style (lower) and calyx (higher) remain (photo by Segundo Leiva G.).

Comment from Dr. Michael O. Dillon

In March of 2014 T. M. corresponded with Michael O. Dillon, informing him that the locality information on his herbarium specimen allowed Segundo Leiva G., Leon Yacher and myself (T.M.) to track down this species. Dr. Dillon, in a return correspondence, wrote in March of 2014:

"I remember that trip [in 1984] because we were threatened by the Sendero Luminoso! We had to backpack in, slept in the abandoned police station in Incahuasi, and eventually told to get out of town, or else..... "Yankee Go Home!"... pretty scary, but we did collect many new species in that area. It was the "school teachers" that interrogated us, the husband in the same room with us, but his wife kept her face a secret by conducting her questions from behind a curtain... we never saw her. The other fellow [with whom I was traveling], Skillman, had a revolver and he slept with the revolver in his hand. I don't think he actually slept while we were there. Ha!
