This population was discovered by Segundo Leiva G. in Peru, La Libertad, a few km before Huaranchal, years before we visited it together in May of 2008.
|
These flowers are male-sterile, and male-sterile flowers have large stigmas (Photo by Mione, Mione et al. 793).

| This flower looks like it is hermaphroditic, unlike those in the photo above. Note that stigmas are smaller on hermaphroditic flowers. To notice this, consider stigma width in this photo as a fraction of corolla tube diameter, and then compare in the male-sterile flowers in the photo above stigma width as a fraction of corolla tube diameter (flower in longitudinal view, photo by Mione, Mione et al. 793) |
Note shape variation among leaves: entire and repand-toothed leaves showing, and a toothed leaf is shown in the last photo of this grouping of photos (Photo by Segundo Leiva G., Leiva et al. 4445 = Mione et al 793) |

Older stems are woody and have lenticels (Photo by Mione, Mione et al. 793) |

We are unable to complete comparison of this collection with Jaltomata cajamarca because nearly all of the flowers of this collection were male-sterile, and so we do not have fully formed stamens or anthers to compare with those of J. cajamarca. This collection differs from J. cajamarca most noticably by having shorter styles and stem hairs that are all gland-tipped (see table immediately below). This collection differs from J. mionei most noticably by having villous stems while those of J. mionei are glabrous, and this collection lacks 10 green maculae in the corolla's throat, present in J. mionei (see table immediately below). In the following table, characters showing no variation were placed in the lowest rows.
