FLORA OF THE SAN ANTONIO MOUNTAINS 1J7 



is known only from 8000 ft. alt. at the Old Gold Ridge Mine. The highest 

 we collected the plant was at 8750 alt. on the saddle between Baldy and Pine 

 Mountain. (No. 13S0, 1527.) 



Castilleja Martini Abrams (?) Here we doubtfully place the common Caslilleja 

 which grows in dry, sunny ground in the Transition Zone. (Nos. 1383, 1700.) 



Cordylanthus Nevinii Gray. Not uncommon under the pines in the Upper Tran- 

 sition Zone. (No. 1662.) 



Cord ylant hus rigidus (Benth.) Jeps. var. fdifolius (Nutt.) Macbride. Common 

 in dry ground below 6500 ft. alt. (No. 1675.) 



Pedicularis semibarbata Gray. Moist shaded ground under the pines, especially 

 in the upper part of the Transition and lower part of the Canadian Zone. In 

 the upper part of Icehouse Canon, alt. 8000-8250 ft., the plant is very abun- 

 dant, nearly carpeting the ground with its fern-like foliage. Collected in the 

 Lower Transition Zone at 6000 ft. alt. in South Fork Lytle Creek and at 7000 

 ft. alt. at the Baldy Lookout. The maximum altitude seen was 8700 ft., at 

 that altitude it was collected on the east slope of Baldy. (Nos. 1274, 1455.) 



OROBANCHACE.E 



Orobanche calif ornicum C. & S. On Eriodictyon at 9000 ft. alt. in the Upper Tran- 

 sition Zone on the Devils Backbone. (No. 1762.) 



Thalesia fasciculata (Nutt.) Britton. Frequent on Eriodictyon, ascending to 

 9000 ft. alt. (No. 1556.) 



Bochniakia strobilacea Gray. Common in the chinquapin belt in all parts of the 

 mountain. It is almost unbelievable to us that this plant has been consid- 

 ered a rarity. On every trip, which we made into the mountains above 8000 

 ft., we have seen literally hundreds of plants. It was most abundant on the 

 south slope of Telegraph Peak, for there the plants grew in dense clusters of 

 thirty or more individuals. These dense masses of plants, due to their growth, 

 caused the upheaval of numerous small areas, the majority of which were a 

 meter in diameter. The condition on Telegraph Peak, however, was not typ- 

 ical of the rest of the mountain. In most parts of the mountain the plants 

 grew singly and were freely scattered over the area which the colony occupied. 

 The favorite host appears to be Arctoslaphylos patula. At 6500 ft. alt. on 

 the south slope of Baldy it was collected on A. Parryana while at 5200 ft. alt. 

 in the Upper Chaparral Belt on the south spur of Cucamonga a few plants 

 were noted on A. tomentosus. The most peculiar thing noted about the plant 

 was that only those flowers which remained underground, two thirds of the 

 inflorescence doing so, matured their fruit. The part of the inflorescence 

 which projects above ground is infertile and has a resemblance to a tama- 

 rack pine cone. (Nos. 1432, 1449, 1554, 1555.) 



RTTBIACE^ 



Galium multiflorum Kell. var. parvifolium Parish. Common among the rocks on 

 Baldy above 9000 ft. alt. A single plant was collected at 7750 ft., Upper 

 Transition Zone, at the Old Hydraulic Mine. This single plant was the only 

 one seen outside of the Canadian Zone. (Nos. 1398, 1691, 1698.)
