12a. Boerhaavia viscosa apiculata Standley, subsp. nov. 
Perennial, ascending; stems slender, minutely and sparsely puberulent 
throughout, slightly glandular above, the stem appearing glabrous to the naked 
eye; internodes long, 8 to 12 cm. ; leaf blades broadly ovate, obtuse at the apex 
and conspicuously apiculate, broadly rounded at the base; petioles about one- 
half as long as the blades; branches of the inflorescence very slender, forming 
a narrow, mostly alternately branched panicle; fruit like that of the species. 
Type collected at Copradia, near Culiacan, Sina loa, Mexico, Octoder 20, 1904, 
Brandegee (in the herbarium of the University of California). 
12b. Boerhaavia viscosa oligadena Heimer], Ann. Cons. et. Jard. Geney. 5: 189. 
1901. 
Boerhaavia ramulosa Jones, Contr. Western Bot. 10: 40. 1902. 
This differs from B. viscosa in the following particulars: The stems are not 
glandular below but have a_ short, seattered, appressed, almost pulverulent 
pubescence; the petioles and the branches of the inflorescence, especially the 
pedicels, have a short, close, glandular pubescence. The variety is founded 
on two sheets, one collected in the Organ Mountains, New Mexico, 1897, Wooton 
421; the other collected on Perico Island, Florida, 1900, Tracy 6654. The two 
plants, although widely separated geographically, appear to be the same in 
all essential characters.
