squarrosa. On the contrary there are numerous speci- 
mens of JD. sguarrosa from the general region whence 
Hartweg’s specimen might have come. Consequently, 
on sound morphological characters, I would refer the 
large-flowered species found on the Pacific slope to D. 
squarrosa and would keep it separate from D.trichocarpa.
