VOL. IV.] Writings of Edzuard L, Greene. 103 



Calochortus Pliimvierce Greene is evidently C Weedii var. 

 purpurascens Watson. 



Calochortics excavatus Greene is a form of C. Nuttallii T. & 

 G. which is rather common in Nevada. 



Calochortus invemistiis Greene has not been accessible to me. 

 It may be C. flexiiosus or C Patmeri^ 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.* 



If Tradescaiitia tuberosa^ Greene were a good species it would 

 yet have, under the rule by which the author changed Horkelia 

 parviflora L,ehm. to Potentilta Andersoni\ Greene, to suffer eclipse 

 on account of the previous T. tubcrosa Roxb. 



Sagittan'a 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 I^athrop 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. 



Jimciis uncial is Greene has been collected by the writer at 

 various places, including the locality at which the type was 

 found. It is certainly /. triformis var. icniflorus Engelm. (/. 

 segetatis 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. 



CiprcssiLS Arizoyiica % Greene is not usually considered dis- 

 tinct from C. Guadattipensis Watson.
