2. Linaria texana Scheele. 
Linaria terana Scheele, Linnaea 21: 761. 1848. ‘‘Zwischen Houston und Austin 
(Texas) haufig: Rémer.’”’? Type not seen or verified, but description evidently of 
the plant here characterized.

June. 
CoLorapo: Boulder: Penard 89. Jefferson: Golden, Pennell 6386. Larimer: Horse- 
tooth Mountain, Pennell 5856. 
Closely related to the eastern L. canadensis (L.) Dum.-Cours., but mostly distin- 
guishable as follows: 
Corolla of early flowers (excluding spur) 7 to 8 mm. long, the spur 2.4 mm. long; sepals 
linear-lanceolate, acuminate to subulate-tipped; seeds sharply prismatic, the 
angles thin, the faces smooth to somewhat tuberculate. Apparently native 
through the eastern Coastal Plain, Massachusetts to Florida and eastern Texas; 
Illinois, and likely introduced elsewhere northward and inland. 
L. canadensis. 
Corolla of early flowers (excluding spur) 14 to 17 mm. long, the spur 5 to 9 mm. long; 
sepals lanceolate to ovate-lanceolate, obtusish to acute; seeds not sharply 
prismatic, the angles more or less rounded, the angles and faces densely 
tuberculate. From South Carolina, southwestern Missouri, Colorado, and Van- 
couver Island southward, within the tropics through the Cordilleras and 
Andes to Argentina and Chile. (2. subandina Diels is evidently a synonym. 
From Florida to Texas, and perhaps elsewhere, intermediates with L. can- 
adensis OCCUY.) ....-- 2. - eee ee eee ee eee eee eee eee eee ceeeecees L. texana.

Collinsia parviflora Lindl. Bot. Reg. 18: pl. 1082. 1827. ‘‘Received by the 
Horticultural Society from Mr. David Douglas, in 1827, by whom it was found in 
the vicinity of the River Columbia.” In account of C. grandiflora Lindl. (op. cit., 
pl. 1107), ‘We learn from [Mr. Douglas] that the species published at folio 1082 of 
the present volume is confined to the rocks in the vicinity of the ocean.” Type 
station evidently near the mouth of the Columbia, probably near Fort Vancouver, 
Washington. Specimen in herbarium of Columbia University, New York Botanical 
Garden, labeled ‘‘N. West. Amer.,”’ received by Torrey from Lindley, if not actually 
an isotype,! is certainly authentic. 
Moist or dry, shady or open, loamy soil, gravelly or rocky, on banks and hillsides, 
at altitudes of (1,350) 1,500 to 2,850 meters; Submontane and Montane zones; flow- 
ering from mid-April to late August, depending upon latitude and altitude. Foothills 
and lower mountain slopes, descending into plateaus along canyon sides and river 
banks; throughout the area. British Columbia and Keeweenaw County, Michigan, 
to northern New Mexico and squthern California. 
Sout DaxKota: Meade County. 
1The word isotype is used to denote specimens of the type collection other than 
the type itself.
