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). |

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) | |
older |
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 | |
Inflorescence |
axillary, 2 (-3) flowered | |
peduncle |
terete, green, to 1.5 cm long, with finger hairs mostly gland-tipped |
|
pedicel |
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 | |
hairs
|
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 |
10 |
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 | |
Stigma |
capitate, darker green than style, bilobed (viewed with a 10X hand lens) |
16, 17, 1, 3, 7, 8, 10 |
Style |
26 - 28 mm long, pale-green | 8, 1, 3, 9, 10, 11,12,16,17 |
Ovary |
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 |
Nectar |
transparent | |
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 |
