Propagation Collection:
Collected in the Yosemite National Park.

Propagation Processing/Propagule Characteristics:
EASE OF COLLECTION: Collection and reestablishment were carried out by Yosemite National Park; data not available at the Lockeford Plant Materials Center. METHOD OF CLEANING: Hammered: 1/8" screen, 750 revolutions per minute; small clipper: screen size #8 & 1/2", air 100% open. Separation poor. TYPE OF MATERIAL COLLECTED FOR PROPAGATION: Cuttings, seed. PROPAGATION METHOD: Cuttings: All leaves except one or two on top were cut off. Stems were cut to approximately six inches in length, and each was dipped 1/2 inch into a hormone powder. The cuttings were then planted 3 or 4 nodes into the soil medium of 5 parts perlite to 1 part peat and placed in the greenhouse side table, directly on the bottom heating coils whose temperature was set at 70§F. Misting was set for 4 seconds at 10-minute intervals. Green-house temperatures averaged 78§F high and 62§F low. The grow lights were on 14 hours each 24 hours. Due to some browning and drying of top leaves, misting was adjusted to keep leaf surface moist. NUMBER OF SEEDS PER POUND: Quantitative values for seed/lb. could not be found. PERCENT GERMINATION: Quantitative values for seed germination could not be found.

Pre-Planting Propagule Treatments:
PRETREATMENT USED: Cuttings : two strengths of Hormex #16 and #3 were used. Seeds : 3 months cold stratification at 35§F mixed with moist vermiculite in a sealed plastic bag.
