Figure 5, above. Note how the style is widest at base and gradually narrows from proximal to distal, and how the stigma is punctiform (about as wide as the distal end of the style). Anthers are undehisced. The corona is evident in this photo (a bowl of tissue on which nectar pools). Mione, Leiva & Yacher 615 after flowers were stored in 70% ethanol for a few years, photo by T.

Figure 6, above. Anther and distal portion of filament of Jaltomata aspera. Unlike other Jaltomata species more of the filament shows in dorsal view (right) than in ventral view (left). Left: ventral view of anther (view from style); right: dorsal view (back of anther); units vertically along right are mm, flowers were stored in 70% ethanol then photographed by Thomas Mione; Mione, Leiva & Yacher 615. | Figure 7, above. One anther was removed to show the corona (bowl of tissue on which nectar pools). At the center of the photo is the ovary of the flower, below the style.

Habit & Height |
This species was described as herbaceous in its protologue, but has also been described as suffrutescent (in the protologue of Saracha lacrima-virginis and on a specimen label [Vilcapoma 2950 There appears to be no correlation between herbaceous/suffrutescent and lomas vs. Andes. 20 - 58 cm | |

Character | Description of Jaltomata aspera |
Low elevation populations grow below 600 m of elevation, while high elevation populations grow above 1,380 m of elevation. The low elevation and the high elevation populations of J. aspera flower at different times of the year, and so are reproductively isolated. And, the Andean (higher elevation) plants may have longer styles. If the low elevation and high elevation populations are considered distinct species Saracha urbaniana would be transferred to Jaltomata as J. urbaniana (Bitter & Dammer). The higher elevation specimens would then all go by this name. And the low elevation (lomas) specimens would continue to be known as J. aspera. According to Arturo Granda Paucar (personal communication, year 2001) this phenomenon, low elevation (lomas) and high elevation populations being considered conspecific, is found in "several species of different families: Hyptis sidifolia (Lamiaceae) grows and blooms with the higher population of J. aspera in the vicinity of Cata, but also is found in Lomas formation along with the lower population of J. aspera. Another example is Ipomoea nationis (Convolvulaceae)...with similar blooming time." |
The three species of section Modillonia are herbaceous, have solitary flowers, a 5-lobed corolla, a corona (figure 7 of this webpage), lack radial thickenings, have basifixed anthers (other species of this genus have the filament inserted into the lower ventral face of the anther), a stigma about as wide as the top of the style (stigma punctiform, not capitate), grow in Peru and produce copious red-orange nectar. A table comparing the species of Jaltomata section Modillonia can be seen on the J. quipuscoae webpage. |

These hills are under 500 m from labels of conspecific collections made in these hills (elevation not mentioned in protologue) | Amancaes is loma-formation (not mentioned in protologue) | "flowering in Oct and Nov" is stated in protologue, so collections were almost certainly made during these months | Ruíz López & Pavón s.n.

"We all remained in Lima until the 19th of December [1781], drying and describing the plants collected on the way from Huaura to Lima, and describing those I found on the outskirts of the capital in gardens and orchards. Among these, I described the following. Jaltomata aspera (as Atropa aspera, page 194) ..." |
