13. Boerhaavia watsoni Standley, sp. nov. 
Boerhaavia spicata palmeri 8. Wats. Proc. Am. Acad. 24:70, 1889, not RB. 
palmeri 8S. Wats. loc. cit. 
Specimens examined: 
MEXxIco: Guaymas, 1887, Palmer 141, type collection; Sonora, Thurber 992, 
CALIFORNIA; Santa Catalina Mission, 1889, Orcutt. 
These Arizona collections are of rather doubtful determination; they seem 
to have the small flowers, included stamens, and slender spikes of B. watsoni, 
yet their localities should place them rather with B. coulteri: 
ARIZONA: Tucson, 1896, Toumey; Oak Creek, 1908, Purpus 8248: Wilmot, 
1903, Thornber 187; Tueson, Thornber 338: Cochise, 1900, Griffiths 1911: 
Camp Verde, 1891, Toumey; Fort Verde, 1891, MacDougal; Arizona, 
1889, Vasey. 
The following are referred here because of their fruit: they are considerably 
more viscid than the type: 
ARIZONA: Small range reserve near Tucson, 1905, Grifiths 6161; fenced 
area, Santa Rita Forest Reserve, 1903, Griffiths 5988, 
14. Boerhaavia coulteri (Hook.) S. Wats. Proc. Am. Acad. 24: 70. 1889. 
Senkenbergia coulteri Hook. f. in Benth. & Hook. Gen. Pl. 3: 6. 1880. 
The following should probably be included in this species according to Doctor 
Watson's interpretation; they differ only slightly from his description of the 
type, which I have not seen: 
ARIZONA: Foothills: of the Santa Catalina Mountains, 1881, Pringle; Rin- 
con Mountains, 1894, Toumey; Mexican Boundary Survey, Schott, 
15, Boerhaavia spicata Choisy in DC. Prod. 137: 456. 1849, 
Type locality, Mexico. 
Of this species, so well discussed by Doctor Watson,” who had seen a portion 
of the type material, I have seen only one sheet of whose identity it is possible 
to feel at all certain, one collected at Culiacan, Sinaloa, Mexico, August 20, 
1904, Brandegee. 
16. Boerhaavia xanti S. Wats. Proc. Am. Acad. 24: 69. 1889,

Brandegee.
