Has. The specimens mixed with #. 46 (Gilia trifida). 
Herba annua? semipedalis. Pubes caulis et ramorum crispa, sub capi- 
tulis sublanata. Folia majora pollice paulo longiora; laciniæ utrin- 
que 2-8 lacinia terminali breviores, omnes fere glabræ virides mucro- 
nula alba terminate. Capitula densa, fere sect. Hugelie, sed bracteæ 
et calycis laciniæ, etsi mucronate, non spinescunt. Bractee palma- 
tim 3-4-fidæ, calycem vix superantes. Calyx 14 lin. longus, pilis 
crispulis basi sublanatus. Corolle laciniæ ovales, obtusiusculæ, 
lineam longæ. Stamina ad faucem inserta, breviter exserta. Benth. 
- This species connects the sections Hugelia and Pseudocollomia with 
Eugilia, and affords additional proof of the necessity of retaining the 
genus Gilia entire, as proposed in the ‘ Prodromus.’ The ovules in the 
flower I examined were certainly solitary in each cell; but my speci- 
men is very young, and I have not verified the structure in other flowers.
