NAUCLEOPSIS. a 



But for the unusual hair-like stigmas that emerge gracefully from 

 the tips of the so-called perianths of Miquel's Naucleopsis, the like- 

 ness of the drawings with my own specimens from Costa Rica would 

 be almost perfect. These delicate organs do not, however, corre- 

 spond satisfactorily with the enlarged illustrations of the same, nor 

 with the description 

 of Naucleopsis glabra 

 Spruce, on which 

 Bureau later found- 

 ed his genus Ogco- 

 deia. We are thus 

 led to suspect that 

 those styles of Nau- 

 cleopsis, as shown 

 in the plate referred 

 to, under I (number 

 omitted) and 31 (all 

 three figures), are fictitious, as are also possibly the strongly marked 

 teeth at the tip of the supposed perianths. Eliminating these details 

 the original description of Miquel would be modified in the following 

 manner : 



Flores dioici. Masculi incogniti. Feminei nudi, bracteolis sublignosis interpositis, 

 in receptaculo convexo deinde ovoideo basi pluriserialiter imbricate numerosis, extimi 

 depauperati. Ovarium inferum, in receptaculo utrinque immersum, uniloculare, 

 uniovulatum, ovulo prope apicem lateraliter pendulo anatropo. Stylus elongatus inter 

 bracteolis inclusus, stigmatibus 2 elongatis. Fructus receptaculo adnato; semen ovoidmm. 



Thus conceived, in accordance with the details obtained from the 

 examination of N. glabra and N. naga, Naucleopsis becomes a well- 

 defined genus, intermediary perhaps between Perebea, Noyera, and 

 Castilla, but with such distinctive characters as to preclude its amal- 

 gamation with any of them. 



Engler seems to have treated the subject in a very desultory man- 

 ner, his main purpose being apparently to reduce the number of genera. 

 This is made evident by his careless handling of Miquel's illustrations 

 of Naucleopsis, reproduced in the Pflanzenfamilien 6 as those of Perebea 



a Naucleopsis Miquel in Mart. Fl. Bras. 4 1 : 120. pi. 35. 1853. Ogcodeia Bur. in 

 DC. Prodr. 17:282. 1873,
