1. Growing on the Galápagos Islands . . . . . . . . . . J. werffii
1. Growing on the mainland. 2.
2. Corolla tubular and green, shrub . . . . . . . . . . . . . . . . . J. viridiflora
2. Corolla rotate (infundibular when partially open), purple, blueish, greenish or white, habit variable. 3.
3. Shrub, corolla purple to blueish, densely hairy with sticky-gland-tipped hairs, fruit orange, J. sinuosa (J. glandulosa, J. vestita).
3. Shrub or herbaceous, corolla greenish or white, the hairs not gland-tipped, fruit color black/purple or red/orange. 4.
4. Corolla white, berries red or orange, above 1400 m. 5.
4. Corolla greenish to pale-green or whitish, berries black/purple, altitude variable. 6.
5. Corolla 18 - 27 mm diameter, stamens 5 mm long, branches and leaves densely villous, J. lojae
5. Corolla 17 - 19 mm diameter, stamens 3.2 - 3.6 mm long, branches and leaves glabrate, J. auriculata
6. Style straight; filaments straight, anthers of uniform size, J. procumbens
6. Style curved orienting stigma to side; filaments curved to sigmoid, anthers of a flower vary in size (most evident during the first day the flower is open when anthers remain undehisced); stigma shallowly grooved to bilobed; fruit fully exposed (the calyx does not hide it) in a view perpendicular to the pedicel at the height of the fruit, J. repandidentata
I collected both J. viridiflora and J. sinuosa in Ecuador, and have grown J. auriculata for study from seeds collected in Ecuador. I have grown many collections of J. procumbens and J. repandidentata for study, from several countries, and I have never seen a morphologically intermediate collection.
I wrote a key to the Jaltomata of Ecuador in approx. 1992, and made the mistake of mailing it to one of the herbaria in Ecuador. I hope they did not keep it, because at that time I made some errors. Some 13 years later, I am now very confident in the key on this page.
