The original description of this species is not available. 

 That of Agardh,^ drawn from Douglas' specimens in Lind- 

 ley's Herbarium, agrees with this in almost all particulars. 

 In Douglas' specimens, the bracts are said to be shorter 

 than the flowers and the raceme is described as short. This 

 has bracts surpassing the flowers in the bud, deciduous 

 when the flowers are in full bloom, while the raceme is 

 nearly a foot long. Mrs. Trask reports this as infrequent 

 on San Nicolas, growing on bare stretches of sand; flowers 

 bright blue. It is probably included under Z,. Chamissonis 

 from San Miguel, Santa Rosa, Santa Cruz, and Santa 

 Catalina,

 nov. 



Entire plant, especially the young parts, pilose with soft, white, curly hairs ; 

 involucre wooly both interiorly and exteriorly, with the teeth of the divisions 

 almost equal, entirely without the long middle tooth of the typical form ; 

 calyx viscid, but free from pubescence. The surfaces of the leaves are 

 sparsely pilose. The plant is less robust and has smaller heads and flowers 

 than thf common form. 



This was compared with the description and figure in 

 Bot. Beech, p. 330, T. 79. T. m/'crodon has been reported 

 from Santa Cruz Island and collected on Santa Catalina 

 by Mrs. Trask. 



As represented in the Herbarium of the Academy, this 

 species is variable. The specimen most nearly like this is 

 one from near Tennessee Cove, Marin Co., Calif., col- 

 lected by the writer. This variety was collected in two 

 localities on moist slopes.

Not reported from the islands, but collected on Santa 

 Catalina by Mrs. Trask. On San Nicolas two forms were
