This is the seed type offered by Sand Hill, Abelmoschus caillei Studies seem to indicate that it might not be an A manihot X A esculentus cross
"This taxon was described as a species in 1988 although it is only known from cultivated material. Classification as a cultivar-group might have been more appropriate. There are strong indications that Abelmoschus caillei is an amphidiploid of Abelmoschus esculentus (L.) Moench (2n = 130–140) and Abelmoschus manihot (L.) Medik. (2n = 60–68). However, the latter species has not been found with certainty in the area of distribution of West African okra, and isozyme analysis has neither confirmed nor rejected the relationships. Abelmoschus manihot differs from Abelmoschus caillei by a smaller number of epicalyx segments (4–8), and much smaller fruits (3.5–6 cm long) which are inedible because they are covered with prickly hairs. Abelmoschus esculentus differs in several respects from Abelmoschus caillei, but the epicalyx offers the best discriminating characteristic: the width of the epicalyx segments is 4–13 mm in Abelmoschus caillei and 0.5–3 mm in Abelmoschus esculentus. The two okra species can be quite reliably (but not with absolute certainty) recognized on the basis of fruit form. Fruits of Abelmoschus caillei are ovoid, whereas fruits of Abelmoschus esculentus are cylindrical to pyramidal."
