We conclude that concurrent photosynthesis is the primary source of carbon for preformation development. Organ primordia initiated in the second year do not receive a substantial quantity of the labeled carbon from reserves stored in the rhizome the previous year. Additional allocation of carbohydrate into preforming organs occurs in autumn after photosynthesis by mature leaves has ceased. During the summer, carbon is allocated directly to preforming organs and rhizomes from the mature leaves. rossii was studied by means of a labeled carbon pulse chase experiment. Acomastylis rossii (Rosaceae) in the southern Rockies initiates leaves and inflorescences 2 yr prior to their maturation and function. Allocation of resources to preforming organs has not been studied in herbs with multi-year patterns of preformation. This extended pattern of development provides a potential means to alleviate an apparent asynchrony between carbon supplied by photosynthesis in the summer and carbon demanded by growth in the spring. Extreme preformation, the initiation of leaves or inflorescences more than 1 yr before maturation and function, is common in arctic and alpine habitats.
