Linn. Trans vol. 17. p. 291. Westwood on Diopsis. "From an examination of 35 specimens of D. Sykesii variation (ie difference) in colour appears to be of the first importance in this group.

Linn. Trans. 17. p. 363. Bentham on Hosackia, distinguished from Lotus (inter alia) by stigma being more distinctly capitate." The latter character, however, is of little importance, being but one of degree;" for all Loti have in fact a capitate stigma "especially when examined in a young state."—
