RYDBERG: Rocky MOUNTAIN FLORA 67 
Glycosma maxima Rydb. sp. nov. 
Perennial; stem 1 m. high or more, puberulent or glabrous, 
pilose at the nodes; lower leaves twice compound, first pinnate and 
the lower primary divisions ternate; the upper leaves ternate or 
twice ternate; leaflets oblong-lanceolate, 5-10 cm. long, minutely 
puberulent; branches of the umbels 9-12, in fruit more or less 
spreading; pedicels in fruit 1-1.5 cm. long; fruit fully 2 cm. long, 
obtuse at the base, contracted above into a beak 2 mm. long; 
stylopodium conical, 0.5 mm. long, about as long as the styles. 
This is related to G. occidentalis Nutt., but the fruit is much 
larger (in G. occidentalis only 12-16 mm., rarely 18 mm. long), and 
the rays of the umbels are in fruit usually widely spreading, while 
in G. occidentalis they are nearly erect. The spreading rays sug- 
gest G. ambigua and G. Bolanderi, but in both these species the 
stylopodium is flatter.

This I think is a good genus, distinct from Carum. Although 
the fruit is almost the same, the habit is quite different. The 
habit of Atenia is the same as that of Eulophus. In fact it is 
hard to distinguish the two genera without mature fruit, both 
having the fascicled tuberous roots, the narrow leaf-segments, 
the same inflorescence and flowers. The only essential differences 
are the deeply concave seed-face with a central ridge and the sev- 
eral oil tubes in Eulophus and the plane face and solitary oil tubes 
in Ataenia. The following species are found in the Rocky 
Mountains:
