This species is said by Blankinship to differ from B. americanum in its low sub- 
acaulescent habit, shorter leaves, wider obtuse involucel bractlets, smaller heads, 
smaller dark purple flowers, and shorter mericarp with fewer oil tubes in the inter- 
vals, and in its alpine habitat. 
ZIZIA Koch, Nov. Act. Caes. Leop. Acad. 12: 128. 1824. 
The following species of Zizia from Georgia has been described 
since the publication of our Monograph: 
Zizia arenicola Rose, Proc. U. 8. Nat. Mus. 29: 442. 1905. 
CARUM L. Sp. Pl. 263. 1753. 
Carum montanum Blankinship, Mont. Agric. Coll. Sci. Studies 1: 89. pl. 4. 1906. 
According to Blankinship it differs from C. gairdneri in its larger size, larger leaves, 
pinnately incised leaflets, large fruit, and longer styles. 
Carum garrettii A. Nelson, sp. nov. 
From a fascicle of fusiform roots, 60 to 100 cm. high; stem stouter than that of C. 
gairdneri; leaves simply pinnate or the uppermost simple, on long petioles gradually 
dilated into the broad base; leaflets from narrowly to broadly lanceolate or oblanceo- 
late, or even ovate, 2 to 6 em. long, from sessile to long-petioled; bracts 1 or 2; 
bractlets several, small, subulate; rays 6 to 12, 2 to 4.cm. long; raylets about 20, the 
pedicels very slender, less than 1 cm, long; fruit ovate, about 2 mm. long; stylo- 
podium low-conical; oil tubes very large, filling the whole interval, only two on the 
narrow commissure; seed terete but for the depressions below each oil tube. 
All the specimens were secured by Mr. A. O. Garrett, of the Salt Lake City High 
School; no, 2053 (in fruit), Wasatch Mountains, Utah, September 6, 1906 (type) ; 
no. 2158 (in flower), City Creek Canyon, Utah, July 25, 1907.. Mr. Garrett is grow- 
ing the species in his garden and reports that it retains the characters as given above.
