338 CALIFORNIA— SUPPLEMENT. {Rosacea. 



in the absence of petals, in the deciduous calyx, and in the much larger and plumose style. In our present 

 species, the calyx is sometimes carried up by the elongated persistent style, on which it remains some way 

 below the apex. 



1. Spirasa (Physocarpus) opidifolia. Linn. — Hook. Fl. Bor. Am. 1. p. 171. — ^. Hook. 

 I, c. — S. capitata. Pursh. — S. ribifolia. Nutt. ms. in Herb. Hook. 



Mr Nuttall's specimen is from the Columbia; his S. pauciflora, from the same country, seems scarcely 

 different. 



2. S. (Spiraria) aricefolia. Sm. — Hook. Fl. Bor. Am. \.p. 173. 



1. Adenostoma fascicidata. Hook, et Am. supra, p. 139. t. 30 A. fasciculata et bre- 



vifblia. Nutt. ms. (in Herb. Hook.) 



We can perceive no difference between Mr Nuttall's two supposed species. His A. brevifolia is but a 

 more stunted plant, with shorter leaves. 



i. Rubus macropetalus (Dough). Hook. Fl. Bor. Am. 1. p. 178. t. 59. 



1. Potentilla glandulosa. Lindl. Bot. Reg. t. 1583. — [3. petalis calyce longioribus. 

 Lindl. Bot. Reg. t. 1973. 



From this we can scarcely distinguish the P. Oregana, Nutt. ms. in Herb, nostr., nor even his P. 

 fissa, ms. 



2. P. anserina. L. 



1. Horkelia fusca (Lindl.) ; glanduloso-pubescens, foliis radicalibus 6-7-jugis laciniis 

 cuneato-oblongis pinnatifidis vel palmatifidis incisis, paniculis corymbosis capitatis, petalis 

 calycem superantibus, calycis laciniis accessoriis integerrimis duplo angustioribus, stipnlis 

 palmatifido-incisis, bracteis palmatis capitulis brevioribus. — Lindl. Bot. Reg. t. 1997. 



Mr Lindley states this to have come from California; but our specimens were collected by Douglas in 

 1835, in the interior, and probably in Columbia. 



2. H. cuneata (Lindl.) ; villoso-pubescens, foliis radicalibus pinnatis 10-12-jugis laciniis 

 subrotundo-cuneatis incisis, paniculis corymbosis capitatis, petalis calycem superantibus, 

 calycis laciniis omnibus integerrimis consimilibus oblongo-lanceolatis, stipulis subintegris 

 ovato-lanceolatis, bracteis tripartitis capitulis villosis brevioribus — Lindl. Bot. Reg. sub 

 folio 1997. — H. Douglasiana. Nutt. ms. in Herb. Hook. 



H. parvifiora, Nutt. ms., differs by being more villous, by having fewer leaflets to the radical leaves, and 

 the accessary calycine segments twice as narrow as the others. It is from the mountains of California. 



3. H. capitata (Lindl); caule basi glabriusculo apice glandulosopubescente, foliis 

 radicalibus pinnatis 5-6-jugis laciniis inferioribus subrotundis incisis basi cuneatis, petalis 

 calycem superantibus, calycis laciniis accessoriis integerrimis multo angustioribus, stipulis 

 integris tripartitisve, capitulis solitariis bractea pinnatifida brevioribus. — Lindl. Bot. Reg. 

 sub folio 1997. 



Lindley mentions that this is a Californian plant ; but our specimens were collected by Douglas on the 

 Cascade Mountains of the Columbia.
