K. BARBIGERA. Eritrichium barligerum, Gray, Syn. Fl. 194. 

 Sat robusta, a basi ramosa ; spicis elongatis. Calyces fructiferi ma- 

 jusculi, lin. 3-4 longi, subpedicellati, sepalis liaud raro apice parum 

 dilatatis. Corolla limbo lin. 1 vel 2 diametro. Nuculae (1-2 vel 2-3 

 rarissime 4 fertiles) ovat;i^, apice subacuminattE, scabro-muricatas, 

 grise:T>, sulco basi in areolam parvam triangularem desinente nee in 

 furcam producto. — We have it only from the southern parts of 

 California and the adjacent western part of Arizona. This and the 

 two following species are either confluent or hard to define. 



h. Sepala fructifera minora (lin. 2-3 longa), setis rigidis albidis seu 

 flavescentibus hispida, cum vel sine pube brevi : corolla limbo lin. 

 1-3 lato ; caulis passim 1-2-pedalis. 



K. INTERMEDIA. Eritrichium intermedium^ Gray^ Proc. Am. Acad, 

 xvii. 225. NucuUe oblongo-ovatac, pi. m. acuminatcE, crebre asperato- 

 muricate, sulco latiusculo nunc fere ad apicem aperto. — Only in the 

 southern part of California, from Los Angeles and San Diego to the 

 Mohave district. There is a small-flowered and a larger-flowered 

 form. 



K. AMBIGUA. Eritrichium muriculatum, Torr. in Wilkes Exped. 

 xvii. t. 13. E, angustlfoUum, Watson, Bot. King Exped. 241, non 

 Torr. E. muriculatum, var. amhiguum, Gray, Syn. Fl. ii. 194. 

 Nuculre deltoideo-ovatce, pi. m. acuminatte, scabrido-muriculat:e, sulco 

 s;)epius inferne aperto basi divaricatim furcato, — Not uncommon from 

 Southern California to Oregon, the interior of Washington Territory, 

 Nevada, and apparently N. Arizona. 



= = Calycis fructiferi ovalis vel oblongi sepala lanceolata, sesqui- 

 lineam vel baud ultra lin. 2 longa, nuculas minus superantia ; costa 

 obscura, setis fulvis. 



K. MURicuLATA. Myosotis muricata, Hook. & Arn. Bot. Beech. 3G9. 

 Eritrichium muriculatum, A. DC. Prodr. x. 132; Gray, 1. c. Sat 

 robusta, 1-2-pedalis, vel minor gracilior; cymis rite evolutis sjippius 

 2-3-radiatis, spicis densifloris ; corollfe limbo lin. 1-2 lato; nuculis 

 lineam longis circumscriptione deltoideo-ovatis obtusis vel acutiusculis 

 scabro-muricatis, sulco tenui basi divaricato-furcato jjlerumque clauso. 

 — Nearly throughout California, extending to Washington Territory. 

 The plant of Douglas, on which the species was founded by Hooker 

 and Arnott, is one of the stouter forms, too young for well making out 

 the fruit. In Proc. Am. Acad. x. 59, I inadvertently took it to be- 

 long to Plagiohothrys canescens.
