Description
Latin Diagnosis - A varietate typica plantis utrinque minoribus, foliolis serratociliatis differt.
Description - This variety differs from the typical in that the leaflets are rather consistently serrulate-ciliate and mostly smaller. The plants tend to be shorter, frequently less than 5 dm. high, and are generally more glandular in all parts than the typical variety. The stipules usually are more rounded at the base. The flowers are about 5-6, rarely 7-8, mm. long. The fruits are commonly 5-8-articulate.

Discussion
As indicated above, this variety is mostly found in northern and eastern South America, at low elevations. The serrulate-ciliate leaflets, the narrow, short-stipitate fruits, and the small flowers are the most distinctive characters. There apparently is intergradation between this and the typical variety; leaves with entire leaflets sometimes occur on plants with predominantly serrulate leaflets.
