Type locality: Not : Yucatan, Fig. 276.—Selenicereus donkelaarii. This species has long been known only from cultivated plants. Schumann reports itas from Brazil but this we are now disposed to question since it has recently been dis-covered by Dr. George Gaumer in Yucatan growing in dense forests, and we now haveliving specimens from his collections. We now find that Major E- A. Goldman collected itsome years ago in Yucatan but it was not recognized at that time. Goldmans plant growsin dense patches on Cantay Island, collected April 22, 1901 (No. 661). Figure 276 represents a sterile branch of the plant as grown in the collection of theUnited States Department of Agriculture. 6. Selenicereus pteranthus (Link and Otto) Britton and Rose, Contr. U. S.
