0.5-2 cm long, gradually reduced upwards, glabrous or hirsute. Spikes 4-8 cm 

 long, 1-2 cm wide, the lowermost verticillasters sometimes remote; bracts 

 ovate, approximately equaling or shorter than the calyx, vestiture as the leaves, 

 acuminate, serrulate pedicels 0-2 mm long, pubescent. Calyx hirtellous 

 tltroughout, the tube greenish near the base and violet above; 4-6 mm long, the 

 teeth violet, deltoid or slightly narrower, 1-1 .5 mm long and acute; corolla blue 

 to violet, hirsutulous without, 7-10 mm long, lobe margins erose. Nutlets 

 yellow-brown, ca. 1.5 mm long (Great Plains Flora Association 1986). 



3. LOCAL FIELD CHARACTERS: Both Agastache urticifolia and A. cusickii 



have white corollas, and neither has leaves that are glabrous on top but white- 

 hairy beneath. They do not overlap in range with A. foeniculum. 



C. GEOGRAPHICAL DISTRIBUTION 



1. GLOBAL RANGE: Southern Ontario west to Saskatchewan, south to Iowa, 

 Nebraska and northcentral Colorado; naturalized in some areas of the 

 northeastern United States and eastern Canada (Great Plains Flora Association 

 1986). 



2. STATE DISTRIBUTION: Dom ( 1 984) cites collections of this species from 

 Gallatin and Sanders cos., which seem to be disjunct from the global range. 

 Location and habitat information for the Gallatin County specimen is not 

 provided on the label, but the collector, P. Hawkins, has other collections 

 which were made from experimental plantings and gardens around Bozeman 

 (Rumely pers. comm.). Both of these western disjuncts may actually represent 

 horticultural plantings or "naturalized" occurrences (see above). Lavender 

 hyssop has also been characterized as present across the eastern 1/4 of Montana 

 (Great Plains Flora Association 1986), but has only one eastern Montana 

 collection in Montana herbaria from Richland County (MONTU). Herbaria in 

 Kansas will be consulted. 



3. STUDY AREA DISTRIBUTION: The species was observed in four 

 scattered locations in the northeastern portion of the Ashland District. 



HABITAT 



ASSOCIATED VEGETATION: The rangewide habitat is characterized as 

 "moist woodland, especially along streams or lakeshores, infrequent in open, 

 wet ditches and prairies at higher elevations" (Great Plains Flora Association 

 1986). In the study area, it occupies the moistest of intact forested settings: 

 localized tall shrub ecotones within pine woodland. The Richland County 

 specimen was collected from American elm-green ash forest at the head of a
