Figure 1. Flowers of Jaltomata spooneri show stigma at same height as dehisced anthers, pollen on the stigma of the flower at left, and the hole in the base of the corolla (flower at left) suggests nectar robbing (Mione et al 800, photo by Segundo Leiva G.)
Figure 2. Jaltomata spooneri, held by the woman in the photo, is locally common (Mione et al 800, photo by Thomas Mione).
Figure 3. Flowers are apparently protogynous: the top-most flower shows undehisced anthers while the lowest two flowers show dehisced anthers of stamens that have apparently elongated
(Mione et al. 800, photo by Thomas Mione).

Character Description Figures on this page
Habit & Height
Shrub to 2 m, perennial,
growing next to and in / among other plants
Branches, young
subterete / angled; sparsely hairy, the hairs dendritic, forked and finger (some gland-tipped, most not)  
terete, with lenticels  
Leaves, size
the blade to 11.7 cm long X 8.7 cm wide, geminate, papyraceous (sturdier than membranous but not coriaceous)  
shape lanceolate or ovate with the apex acuminate, the margin entire to somewhat repand  
hairs the blade minutely pubescent, the hairs simple and / or dendritic, the margin ciliate  
petiole to 2.7 cm  
axillary, 2 (-3) flowered  
terete, green, to 1.5 cm long, with finger hairs
mostly gland-tipped
green, having 5 raised longitudinal ridges, with finger hairs mostly gland-tipped, to 2 cm long  
Calyx at flowering
green, on flowers of Mione et al. 800 pigmented purple between lobes on abaxial face (showing upward),
the lobes triangular,
23 mm lobe tip across to lobe tip, abaxially a mixture of uniseriate unbranched (finger) and forked hairs all gland-tipped
shape / position when flowering rotate to somewhat reflexed 3
at fruit maturity
25 mm from lobe tip across to lobe tip with unripe fruit, possibly somewhat larger with mature fruit
Corolla color
pale-green, the veins pigmented purple (Mione et al. 800) or unpigmented (Mione et al. 799) 5
shape and size
tubular, the tube 1.2 - 1.7 cm long on herbarium specimens, 1.5 - 2 cm long measured in the field, 7 - 10.5 mm across perpendicular to the length where widest (herbarium specimens); the limb recurved, to 3 cm in diam on herbarium specimens depending on how the corolla was pressed, 2.5 cm in diam measured in the field  
lobes / lobules
alternating, totaling 10; the lobes cream-green, the lobules cream  
abaxially (outer) simple usually not gland-tipped but sometimes gland-tipped,
inner extremely short and simple,
the margin ciliate
Stamen length including anther
to 27 mm long including anther  
length stamens exserted beyond distal end of corolla
(applicable if corolla has a well-defined tube)
commonly to 12 mm, up to 15 mm
(measurements made on pressed specimens)
1, 3, 7, 8, 9, 10, 11
yes: radial expansions of the bases of the stamens, adnate to the corolla, create nectar troughs between the radial expansions / thickenings 12
base expanded laterally? no  
filaments unpigmented, glabrous  
anther color yellow  
anther size 2.1 - 2.7 mm long (dehisced, herbarium specimens);
3 mm long X 2 mm wide (field notes);
sagittate or not, depending on orientation when pressed
anther mucronate/mucronulate mucronulate both Mione et al. 799 & 800, field notes
insertion of filament on the lower ventral face of anther  
anthers of a flower open simultaneously? some of the photos taken in Peru (Mione et al. 799 & 800) show some but not all of the anthers of a flower dehisced, thus dehiscence is nonsimultaneous at least in some instances  
pollen quantity per flower 92,500 - 109,000 (n = 2 flowers) Mione et al.799 & 800, counts by Emmett P. Varricchio, 2012, flowers collected in Peru (not grown for study)
pollen grain size 32.5 - 37.5 µm,
mean 34.69 µm
Mione et al. 800, 18 grains, flower collected in Peru and stored in 70% ethanol, measured 2012
corona no  
capitate, darker green than style,
bilobed (viewed with a 10X hand lens)
16, 17, 1, 3, 7, 8, 10
26 - 28 mm long, pale-green 8, 1, 3, 9, 10, 11,12,16,17
green; the disk orangish and about 20 - 30% the height of the ovary 13, 14, 15
Ovules per ovary
225 - 236 (n = 2 flowers)
13, 15
Herkogamy only sometimes: several of the flowers in figure 11 show a few mm between stigma and dehisced anthers. Fig. 1 no, Fig.11 yes
Protogyny yes 3, 10
Fruit color (at maturity) and size
mature fruits not seen, most likely orange (a local person described the ripe fruit as "amarillo")
to 1.3 cm diameter but fruits measured were unripe and so mature fruits may be slightly larger

Nearly all of the ovary wall was removed to reveal ovules of Jaltomata spooneri; same ovary as shown in the figure immediately to the left.
