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

2. The lighter green leaves and white flowers, including those of the branch extending up to the far left, are those of Jaltomata atiquipa

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).

Habit & Height
Shrub to 1.5 m high 2
Branches, young

older
hollow, brown, glabrate with lenticels, to 1 cm diameter 8
Leaves, size the blade to 13 cm long X 11 cm wide 11
shape the blade ovate, the larger leaves basally truncate, sometimes basally oblique, the apex acute or subacute, sometimes acuminate, the margin subentire to toothed 11
arrangement and hairs alternate, sometimes geminate; young leaves puberulent becoming glabrate

no data
 
Corolla color
white with green throat (10 green maculae in base) 1, 2, 3, 4, 7, 13
shape and size
crateriform, to 15 mm diameter when pressed 1, 3, 4, 12, 13
lobes/lobules
5-lobed 1, 3, 4, 13
hairs
the hairs of two types: nonglandular finger hairs (uniseriate) 0.8 mm long,
and stalked multicellular glands 75-85 micrometers long
 
no 13
Stamen, length including anther 4 mm 1
filaments whitish, glabrous except for the base where the hairs are 0.21 mm long 1, 6
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)

pollen grain size

diameter: range 25 - 30 micrometers, mean 28.67 micrometers
(24 grains, type collection stored in 70% ethanol until Feb 2011 when grains were stained in cotton blue in lactophenol and measued by T. M. in polar view)

 
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

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!
