lishing a graduated series of structure between the most 
highly devoloped forms of Rosacez, and such imperfect 
forms as we find in Sanguisorbea. 
* A hardy perennial, flowering from June to August, and 
propagating readily by means of seeds, or by division of 
the roots. 
The other species above alluded to are the following:— 
H. cuneata ; villoso-pubescens, foliis radicalibus pinnatis 10-12-jugis laciniis 
subrotundo-cuneatis incisis, paniculis corymbosis capitatis, sepalis integer- 
rimis, bracteis tripartitis capitulis villosis brevioribus. Varies in size 
from a span to a foot or more in height. California, Douglas. 
H. hirsuta; basi hirsutissima ‘apice glandulosa, foliis radicalibus pinnatis 7-8- 
jugis, laciniis angustis cuneatis incisis, paniculis corymbosis capitatis multi- 
floris glandulosis calvis, sepalis integerrimis, bracteis brevissimis 3-5-partitis. 
A very striking 'species, covered with long, loose, coarse hair near the 
base, but hairless and simply protected by minute glands towards the flowers. 
The corymbs are more flat and compact than in the others. California,

H. capitata ; caule basi glabriusculo apice glanduloso-pubescente, foliis radica- 
libus pinnatis 5-6-jugis laciniis inferioribus subrotundis incisis basi cuneatis, 
capitulis solitariis bracteá pinnatifidà brevioribus, sepalis integerrimis.——
