While engaged in the histological portions of a study of the apically dehiscent anther,* I found myself particularly interested by three forms which have not been fully understood by systematists, and since it will probably be a considerable time before my final memoir can appear it has seemed advisable to offer my notes on these genera in a form and place which will render them more accessible to the taxonomist, for whom they are particularly intended, than they would be in a thick paper of morphological and ecological nature. The forms to be considered here are Dicoryni'a and Dutparquetia of the Legumniuosae, and Strunzpfia of the Rubiaceae. We may confine our attention strictly to the morphological features, leaving histological detail for the special treatment. The first form is Dicorynia Benth. t The androecium of this peculiar South American representative of the Cassieae has been characterized as follows: Stamens 2, free, unequal; filaments short and thick; anthers basifixed, oblong, short and thick, that of the shorter stamen longer, often 8-locellate, dehiscing at the apex. The form of the anthers in the specimen examined agrees very closely indeed with that figured in Flora Brasiliensis. Both anthers are smooth, brown in color and very hard. A series of sections was secured and mounted in sequence. Figures i, a and i, b represent sections from near the base and tip of the smaller anther, the one borne on the longer filament, and show that it has the 4-locellate structure of a typical anther. In systematic works the larger anther, borne on the shorter filament, has been described as 8-locellate, and the first prepara-
