1. In the center flower the stigma is green and 4 anthers have completely dehisced while the lowest anther is in the process of dehiscing (Mione et al. 804, photo by Segundo Leiva G.) |
2. The lighter green leaves and white flowers, including those of the branch extending up to the far left, are those of Jaltomata atiquipa (White ruler 21 cm long, Mione et al. 804, photo by Segundo Leiva G.) |

6. Flower was photographed through dissecting microscope after ovary was dissected to reveal ovules and ovarian disk (a disk of presumably nectary tissue that surrounds the ovary). The blue arrow shows the scar left when the style broke off from its attachment at this location (Flowers from type collection stored in 70% ethanol until dissected; dissection and photo by Thomas Mione, January 2011). |

|
no | 13 | |

anther color & length | cream-colored prior to dehiscence, 1.1 - 1.4 mm long, emucronate | 1, 6,12 |
anthers of a flower open simultaneously? | to answer this question (January 2011) all photos taken (when the type collection was made) were carefully observed: all flowers but one show either dehisced anthers are undehisced anthers suggesting that for the most part the anthers of a flower do dehisced simultaneously or nearly simultaneously. A few photos do show some differences in timing of dehiscence among the anthers of a flower. | 1 |
pollen quantity | per androecium: range 58,250 - 99,500, mean 69,950 (n = 5 flowers of the type collection) |
counts by Alison Cameron Jan 2011 |
pollen grain size | diameter: range 25 - 30 micrometers, mean 28.67 micrometers |
|
Gynoecium |
glabrous except for stigma papillae | 6 |
Stigma |
green, capitate with a shallow medial groove, exserted beyond the dehisced anthers | 1, 13 |
Style |
whitish, 6 mm long | 3, 4, 6 |
Ovary |
green; the ovarian (nectary) disk orangish and fairly thick, occupying about 60% of the height of the ovary | 6 |
Ovules per ovary |
81 - 94 (four flowers, mean 88.75) | 6 |
Nectar | red/orange nectar not present | 1, 3, 4, 7, 12, 13 |
Herkogamy | Yes, the stigma is exserted a few mm beyond the dehisced anthers | 1, 4 |
Protogyny | To answer this question all photos taken (when the type collection was made) were carefully observed: there are a few open flowers that show undehisced anthers and are thurs showing a pistillate phase of uncertain duration. There is no way of knowing, with the information at hand, if the duration of protogyny is say one hour or one full day, and there is no way of knowing if all flowers are pistillate before becoming functionally hermaphroditic (comments of January 2011). |
only figure 12, all other figures show functionally hermaphroditic flowers |

15. Town of Atiquipa. Hills showing behind town are too low for the Jaltomata species shown on this page and one would need to walk uphill for about an hour to an hour and a half to see the fog and shrub habitat that includes the Jaltomata species of this page (photo by Thomas Mione) |

Doy gracias a Julieta Delatorre y Freddie de Atiquipa, y Aldo Orgega Paredes para depositar una espécimen de esta especie en el herbario de CUZ. ¡Su espécimen me puso sobre aviso a la existencia de esta especie! |
