broadly ovate, 2.5 mm. long, acute; petals elliptic or elliptic- 

 obovate, about 4 mm. long, strongly concave, free or slightly 

 united at the base; ovary rudimentary: pistillate flowers and 

 fruit unknown. MEXICO. State of Vera Cruz: Carrizal, 12 to 

 14 May, 1901, E. A. Goldman, no. 712 (lib. U. S. Nat. Mus. ; 

 fragment and photograph in hb. Field Mus.). 



The species here described is apparently nearest related to 

 Hechtia Schottii Baker, and H. texensis Watson; from the for- 

 mer it differs in having longer leaves, more profusely branched 

 inflorescence, and somewhat smaller floral bracts; from the 

 latter it is readily separated by the longer leaves, the presence 

 of conspicuous tufts of tomentum in the upper axils of the 

 leaf-spines, and by the smaller and more scattered flowers.

In the herbarium of the Field Museum there is a specimen, 

 collected by Schott in Yucatan, which is unmistakably refer- 

 able to Hechtia. The label accompanying the plant bears no 

 number, and likewise no time of collection, but it bears the 

 data "Maxeana." The specimen consists of leaves, an inflores- 

 cence of staminate flowers, and a portion of a panicle bearing 

 mature fruit. The characters exhibited by all these parts 

 agree well with Baker's description, hence the plant is confi- 

 dently referred to the above species; and, moreover, it probably 

 represents a part of the same collection on which the species was 

 founded. With this species are also identified specimens collect- 

 ed at Xcholac, Yucatan, Dr. Geo. F. Gaunter, no. 578 (hb. 

 Field Mus.).

Fruiting specimens of this species were collected by the writer 

 at Izamal, Yucatan, in February of 1906. These agree in habit 

 and foliar characters with flowering specimens which were 

 secured in the same locality by Dr. A. Schott and also by Dr. 

 Geo. F. Gaumer. The species is widely distributed, occurring 

 from Mexico to South America, and although well known from 

 flowering specimens, the fruit seems not to have been hitherto 

 described, hence the following characterization is here given:
