Notes: Elven and Murray: The wide span in the few chromosome number reports for Castilleja caudata is intriguing. The morphological pattern in material identified as this species suggests that it partly has been used as a dumping place for things not fitting elsewhere, both in northwestern North America and in northeastern Asia. It is the most common and the most weedy of Castillejas in northwestern North America and partly also in Chukotka.
Pennell (1934) considered C. annua to be a local endemic of the Fairbanks area in central Alaska. He was followed by Hultén (1949a). Hultén (1968a) seems to have included it in C. caudata to which it must be closely related. In a revision of herbarium specimens of Castilleja in 1999-2000, Egger accepted C. annua and enlarged the range appreciably to cover several of the major interior valleys of central and eastern Alaska north to the southern Brooks Range. Castilleja annua is intermediate in size and some other features between C. caudata and C. yukonis. It is probable that the majority or all reports of C. yukonis from Alaska are based on such plants. It is also feasible that the varied chromosome numbers reported for C. caudata may hide several taxa and that C. annua may be one of these. Egger (2008) had changed his opinion and commented: "I regard C. annua Pennell as synonymous with C. pallida var. caudata. The type collection of C. annua represents an inconstant morph with small flowers and branching stems found sporadically throughout much of the range of var. caudata and usually grading into the more typical morphs within populations and local areas".
