The following species ascribed to Echinocystis probably belong in 

 Bchinopepon, but I only know them from descriptions and therefore 

 leave them in the old genus: 



Echinocystis yhttinosa Cogu. 

 Echinocystis yemeUa Cogu. 

 Echinocystis muricata Cogu. 

 Echinocystis polycarpa Cogu. 

 Echinocystis araneosa Griseb. 

 Echinocystis pnuiculata Cogn. 



The following species referred to Echinopepon and Echinocystis § 

 Echinopepon are to be excluded from Echinopepon: 



Echinopepon bigelovii Wats. = Brandegea sp. 

 Echinopepon palmeri Wats. = Bran deyea sp. 

 Echinopepon insularts Wats. = Vaseyanthus sp. 



Echinopepon purvijlorus Wats. — Brandt-yea sp. 



VASEYANTHUS. 



The genus Vaseyanthus was first described by Professor Cogniaux, 1 

 and was baaed upon a single species, V. rosei. Previously, however, 

 Professor Cogniaux had described an Echinocystis under the name 

 E. brandegei, for which he constructed the separate section Pseudo- 

 echinopepon. This species belongs more properly in the genus Vasey- 

 anthus, and 1 have no hesitancy in referring it there. 1 fear, however, 

 it is too near V. rosei, and have little doubt but it will eventually be 

 combined with it. 



There is still another somewhat anomalous species that I should refer 

 here, viz, Echinopepon insularis Wats. 



This species, while more like Echinopepon than either of the above, 

 still differs from it in some important particulars. 



The transfer of these two species to Vaseyanthus will make Echinope- 

 pon a more consistent genus. 



The genus Vaseyanthus has a small globose fruit covered with short, 

 stiff spines, capped with a cone-shaped caducous beak; its walls are 

 very thick; it has a single cell with two ovules and mostly one seed. 

 The genus is confined to Lower California and the adjacent islands. 

 The species with synouomy and collections may be brought together as 

 follows: 



Vaseyanthus rosei Cogu. Zoo, 1 : :568, /. 11. 1891. 



Collected by Dr. E. Palmer near La I'm/., Lower < 'alifornia, January '20 to February 

 5, 1890 (No. 102) and at Carmen Island, November 1 to 7, 1890 (No.«37). 



The former specimen is the type (No. 560) and is deposited in the National Herba- 

 rium. 



Vaseyanthus brandegei (Cogu.) Rose. Echinocystis orandegei Cogn. Froc. Cal. Acad. 

 uer. 2, 3:59. 1890. 



Collected by T. S. Brandegeo, La Paz, Lower California, November 1, 1890. Dupli- 

 cate specimens of the type (No. 705) are deposited in the National Herbarium.
