differs further in its glabrous or glabrate stem. So far as known 

 true C. parviflora is found only near the Alaska coast. 



In 1834 Nuttall* described two species of Euchromu collected by 

 Wyeth on the borders of Little Goddin River. Through the courtesy 

 of Mr. Stewardson Brown, of the Philadelphia Academy of Sciences, 

 I have been able to examine the original specimens of these two 

 species, E. angustifolia and E. Bradburii. These specimens, like 

 so many of Nuttall's types, are very fragmentary, but they show the 

 characteristic lobing of the leaves and bracts, and the pubescence 

 sufficiently to identify them with more complete material of recent 

 collectors. Euchroma angustifolia has very narrow leaves, with two 

 very divaricate linear lateral lobes, which, with the stem, are cov- 

 ered with short cinereous appressed pubescence, and many longer 

 pilose-hispid hairs. Though Nuttall described this species as " three 

 to four inches high," the original specimen from Wyeth seems more 

 like the upper portion of a taller plant. E. Bradburii has the 

 leaves broader than E. angustifolia, lanceolate or oblong-lanceolate, 

 somewhat cuneate below, and with two pairs of ascending or some- 

 what divaricate linear-lanceolate lateral lobes. The stems and 

 leaves of E. Bradburii are more or less pilose, but with none of the 

 characteristic hispid hairs of E. angustifolia. The bracts of E. an- 

 gustifolia were said by Nuttall to be " (apparently) lake red," while 

 those of E. Bradburii were "(apparently) scarlet." In 1838 Donf 

 transferred these two species to Castilleia. 



Some months later, in 1838, BenthamJ described Castilleia hiapida. 

 From his description alone it would be difficult to separate his plant 

 from C. angustifolia (Euchroma angustifolia, Nutt.), but the plate §, 

 which he cites, shows his species to be a much stouter plant, with 

 longer pilose-hispid pubescence, and with the lateral lobes of the 

 leaves ascending rather than divaricate. This plate, which had been 

 referred by Lindley to the Eastern C. coccinea, is well matched by 

 recent specimens from the Northwest.
