Monographs Details: Naucleopsis krukovii (Standl.) C.C.Berg
Authority: Berg, Cornelius C. 2001. Moreae, Artocarpeae, and (Moraceae): With introductions to the family and and with additions and corrections to Flora Neotropica Monograph 7. Fl. Neotrop. Monogr. 83: 1-346. (Published by NYBG Press)
Discussion:The free parts of the perianth of the pistillate flower can be to 1 cm long and may vary from distinctly aculeate to pyramidate to almost cushion-shaped. Their indumentum may vary from rather sparsely puberulous to subvelutinous. The remarkable circular holes in the lamina (possibly caused by some fungus) are found in almost all additional collections. Reproduction sometimes starts in treelets of about 3 m tall.

The collection D. N. Smith 3900 largely matches Naucleopsis krukovii, but the pistillate inflorescence is distinct in the very short, ca. 1 mm high, cushion-shaped free parts of the tepals and peripheral "pseudobracts." PERU. Pasco: Prov. Oxapampa, nr. confluence of Río Palcazu and Río Iscosacin, 23 Apr 1983 ([female] fl-fr), D. N. Smith 3900 (MO).
