CATALOGUE OF SPECIES. 1G5 



Cryptanthe barbigera (Gray) Syn. Fl. ii. pt. i. 194 (1878), under Eritrichium; 

 Greene, Pittonia, i. Ill (1887). Type locality not given; range, "S. California, from 

 Santa Barbara Co. to S. Utah and Arizona." 



in Mill Creek Canon, Panamint Mountains (fu>. 803). 



Cryptanthe cycloptera Greene, Bull. Cal. Acad, i. 207 (1885), under Krynitzlia; 

 Greene, Pittonia, i. 120 (1887). Type locality, "Arizona, at Tucson." 

 The characters originally assigned to this plant, "Nutlets all winged; wings 

 * * ■* continuous across the base [of the nutlet] ; ventral face not muricate," 

 distinguish it clearly from the original of C. pterocarya. In that plant one of the nut- 

 lets is uniformly wingless, while the wing in the others does not extend across the 

 base of the nutlet, the inner face of which is usually muricate. In both plants, par- 

 ticularly C. cycloptera, the wings vary freely from entire to deeply eremite. Dr. Gray 

 united the two plants under C. pterocarya, but I have not found a satisfactory series 

 of intergrades. The species was seen in Furnace Creek Canon (No. 414), and in 

 Johnson and Surprise canons (No. 720), Panamint Mountains. 



Cryptanthe flaccida (Lehm.) Pug. ii. 22 (1830), under Myosotis— Dough MS,; 

 Greene. Pittonia, i. 115 (1887). Type locality not given; plant collected by Douglas. 

 Between Kernville and Havilah (No. 1054). 



Cryptanthe intermedia (G ray) I'roe. Amer. Acad. xvii. 225 (1882), under Eritri- 

 chium; Greene, Pittonia, i. 114 (1837). Type locality, "southern part of California 

 to adjacent Arizona." 



In the Vegas Wash (No. 423), in Furnace Creek Canon (No. 442), in Johnson 

 Canon (No. 558), in Hall Canon (No. 700), and between Kernville and Havilah (No. 

 1058). This is one of the most abundant species of the genus in the Lower Sonorau 

 zone. 



Cryptanthe pterocarya (Torr.) Bot. Wilkes Expel, xvii. 415 (1874), under Eritri. 

 chiinit; Greene, Pittonia, i. 120 (1887). Type locality, " Walla Walla River, Washington 

 Territory." 



Near Crystal Spring, Coso Mountains (No. 020). 



Cryptanthe racemosa (Gray) Proe. Amer. Acad. xvii. 226 (1882), under Eritri- 

 chium — Wats, in herb. ; Greeue, Pittonia, i. 115(1887). Type locality, "Mesquite 

 Canon, San Bernardino County, California." 



This is the only suffrutescent Cryptanthe known. It occurred in a eafion of the 

 Funeral Mountains, opposite Bennett Wells (No. 206), and in Surprise (No. 704; and 

 Willow Creek canons, Panamint Mountains. The species always grew in canons 

 and always within the limits of the Lower Sonoran. One specimeu was collected, 

 the woody base of which was 7 mm. in diameter. 



Cryptanthe ramosissima Greene, Bull. Cal. Acad. i. 203 (18^5), under Krynitskia; 

 Greene, Pittonia, i. 116 (1887). Type locality, " Mohave Desert." 



Near Bennett Wells, Death Valley (Nos. 107, 480, 2150), in Furnace Creek Canon, 

 Funeral Mountains (No. 446), in Surprise Canon, Panamint Mountains (No. 701). 

 The specific name is probably untenable, since it was first proposed by Dr. Gray 1 

 as a substitute for the older Eritrichium (now Cryptanthe) racemosam, and at that 

 time included only by an error the plant to which Professor Greene has limited it. 

 The species is abundant on the open gravelly mesas of Death Valley, and probably 

 in many other parts of the Lower Sonoran zone. 



Cryptanthe recurvata sp. nov. PLATE XVI. 



Plant annual, 10 to 15 cm. high, sometimes depauperate and smaller; stem erect, 

 usually branching, appressed-hirsute, the hairs on the lower part of the stein some-
