FLORA OF THE SAN ANTONIO MOUNTAINS 115 



dian Zone at, 9500 ft., and no doubt the type was collected there. The species 

 does not grow on Baldy Summit for it reaches its upper limits at about 9700 

 ft . alt. The lowest station noted for the plant was at 6000 ft. alt. on the Baldy 

 Trail just above Bear Flats where it grows on the border line between the 

 chaparral and pine belt. At this low station the plant was in flower during 

 the first of July while on Little Baldy it was not in full bloom till the last of 

 August. (Nos. 1261, 1420, 1421, 1422, 1449, 1549, 1571, 1693.) 



Monardclla linoides Gray var. stricta Parish. This was collected in Swartout 

 Valley between 6000 and 8000 ft. alt. at various times by Dr. Hall. 



Salvia apiana Jeps. An occasional entrant into the pine belt. Seen as high as 

 8000 ft. alt. An abundant species on the mesas along the south base of the 

 mountains. 



Scutellaria angustifolium Pursh. Collected by Dr. Hall (No. 1251.) on the 

 north base of the mountain at 5600 ft. alt. 



Slachys albens Gray. Occasional in moist ground in the Lower Transition Zone. 

 In the Upper Transition Zone, alt. 8000 ft., at the Old Gold Ridge Mine. 

 (No. 1604.) 



SOLANACE.E 



Nicotiana Bigelovii Wats. A few plants along the trail at 5400 ft. alt. in Icehouse 



Canon. 

 Solatium Xantii Gray. Frequent in shaded ground in the Lower Transition Zone. 



SCROPHULARIACEjE 



Collinsia Childii Parry. Locally abundant on moist, cool, shaded canon-sides at 

 4500 ft. alt. in Cascade Canon. Lower Transition Zone. (No. 1282.) 



Collinsia callosa Parish. The type of this species was collected by Hall in Swart- 

 out Valley. Dr. Hall collected other specimens at 6500 ft. alt. in Lytle 

 Creek. 



This species may be only a coarse xerophytic form of the last species. It 

 differs from Childii in being stouter, lower and in having shorter, stiffer 

 and more widely spread branches. Its leaves are shorter, broader, thicker in 

 texture and nearly sessile. The calyx is twice as broad, square at the base, 

 and with thick, nearly deltoid calyx lobes which have barely apparent mid- 

 ribs. These characters coupled with its general distribution, which consists 

 of the desert slope of the San Antonio Mts. and the various small mountains 

 of the Majove Desert, would make the aforementioned relationship to C. 

 Childii at least plausible. 



Collinsia Torreyi Gray var. Wrightii (Wats.) Johnston, comb. nov. C. Wrightii 

 Wats. C. monticola Davids. Colonies of this plant are frequent under 

 the pines in the upper part of the Transition Zone and in the Canadian Zone. 

 Its range seems to coincide with that of Castanopsis Tne highest station 

 that we know for this interesting little plant is at 8700 ft. alt. on the saddle 

 between Baldy and Pine Mt., but Davidson cites under his species a col- 

 lection by Mr. Burlew from Baldy Summit. We have seen a collection by 

 Dr. Hall (No. 1239) from near the summit of Baldy at 9700 ft. alt. The plant
