regarded by Hegel, i.e., D. murlcella, Vahl., with pubescent silicles, and a 

 smooth form of D. tiemoralis. 42. D. nemoralis, L., two pubescent forms*

 46. Thlasfi cociileariforme, DC. Common at all heights. 47. Physaria didy- 

 mocarpa, Gray, var. ? The same as Parry's 101, but more Tioary, and with a 

 longer slender style. Mature fruit and seeds being still wanting, it yet re- 

 mains as doubtful as before whether this is a form of Hooker's species. 48. 

 Vesicaria Ludoviciaxa, DC. 49. Vesicaria Montana, n. sp.,* from the middle 

 mountains ; also collected UsTyear at Eureka by Mr. Howard, but without 

 fruit. gjQ. Stan ley a integrifolia, James. 5L Thelypodium (Pachypodium,

 tKe~ size of those of the ordinary state. It is No. 428 of Parry 'a separate col- 

 lection.

 Gray. 6& Sagina Linn^i, Presl. 69. Arenaria (A*lsi»b) Rosbii, R. Br., the 

 taller stems 3-5-fiowered, pretty clearly a mere arctic-alpine form of A.
