Diagnosis: the form Lisarassa has a number of characters aligning it with Caiceda and partially with tocanum, varies from them in a more intense color of tubers, stem, peculiar corolla color, descent pubescence and other characters.
Tubers are oval , blue, entirely colored (or speckled). Stem is bluffy colored.
Leaves are usually have 5 pairs of leaflets, there are usually 2 pairs of primary leaflets in a series, more seldom 3 pairs, not basiscopic. There are 1-2 pairs of secondary leaflets, acroscopic – 1 pair. The leaf is less split, than by Caiceda, especially on side offshoots, leaflets are wider. These characters align Lisarassa with tocanum. Adjunction of the peduncle, apparently, like by tocanum and Caiceda (in the second tier without “nozhk”, on the opposite or slightly above the leaf).
Pedicle articulation is colored. Calyx is similar to ñaiceda, acumens are also pressed in the bud and in the berry. Several acumens can be sickle-shaped.
Corolla is dark-violet with black-violet star, of a more blue shade than by Caiceda. Tube is slightly longer than the filaments, like by the previous forms. Stamen filaments are colored. Anthers are large, longer than by Caiceda, length 7-7,5-8,5 mm, width of base 2,75 mm, apex 1,75 mm. Style is 11 mm long and more, strongly inclined, almost arcuate. Stigma is a little abjointed from the style.
Cultivated in Columbia and vicinities of Bogota, in particular in Chipaque.
Accessions ¹¹ 35, 36, 37, 51, 53, 54, 56. Indigenous name: Lisarassa.
By seeding with seeds a thick peduncle remains, long pubescence, shape of calyx and stigma.
Anther position and peduncle color vary.
