Calochertus Plummere Greene is evidently C. Weedii var. 
purpurascens Watson. 
Calochortus excavatus Greene is a form of C. Nuttall? T. & 
G. which is rather common in Nevada. 
Calochortus invenustus Greene has not been accessible to me. 
. It may be C. flexuosus or C. Palmeri, both of which have been 
found not very far away. It might be well for Mr. Greene, 
before making any more species on such grounds, to read 
with care some recent observations by S. B. Parish on the 
variation not only of the markings but of the gland.* i 
If 7radescantia tuberosay Greene were a good species it would 
yet have, under the rule by which the author changed Horkelia 
parviflora Lehm. to Potentilla Andersontt Greene, to suffer eclipse 
on account of the previous 7. ¢uwberosa Roxb. 
Sagtitarta Sanfordi Greene collected first in the sloughs about 
the city of Stockton and since that time on the margins of pools 
along the county road between Lathrop and Banta was so imper- 
fectly described by the author that even the section to which it | 
belonged could not be made out. It proves to belong to the 
second division of the genus as formulated by Micheli. The 
pedicels of the female flowers are much thickened (the flowers 
are white), and the lamina of the leaf often considerably 
expanded. It has not the appearance nor the distribution of an 
indigenous plant, but has not so far been identified with any 
foreign one. 
Juncus uncialis Greene has been collected by the writer at 
various places, including the locality at which the type was 
found. It is certainly /. ‘viformds var. uniflorus Engelm. (/. 
segetalis Engelm.). The seeds in our specimens are faintly 
ribbed and cross-lined. The author will find that the degree of 
maturity of the seeds has much to do with the distinctness of 
their markings. 
Cupressus Arizonica § Greene is not usually considered dis- 
tinct from C. Guadalupenszs Watson.
