Description - This differs from the typical variety in that the fruits are puberulent and/or beset with glandular hairs. The stipules commonly are hispid at the point of attachment. The bracts are cordate. The flowers commonly are 6-8 mm. long.

Discussion
Poiret, in the original description, suggested that this might be a variety of Ae. americana, and it is so treated in this paper. It is distinguished from the typical variety by the indument on its fruits. There may be a sparse development of glandular hairs on the fruits or there may be puberulence, which I believe to be incipient glandular development. Occasionally there is intergradation from puberulent to hispid fruits, or to the eglandular condition of typical Ae. americana. There is also considerable variation in the size of mature fruits, but it seems impracticable to make any satisfactory delimitations on that basis. It has not been possible, thus far, to locate the type of Ae. guayaguilensis. The description, particularly "leaflets, which are serrated at the apex," indicates the series Americanae. The fruits are described as "smooth," which would suggest typical Ae. americana. Most specimens of Ae. americana, sens, lat., which I have seen from the vicinity of Guayaquil exhibit puberulent fruits but appear smooth to the naked eye. Truly glabrous fruited specimens are the rarities. Don proceeded his description of Ae. guayaguilensis with a description of Ae. americana L., presumably considering the two entities to be different. In the present paper, Ae. guayaguilensis is being interpreted as Ae. americana var. glandulosa.
