The native community was left intact with the exception that all naturally occurring Gilia
was removed from the blocks.
capitata capitata is common on the dry rocky slopes of central and northern California's Coast Range.
Although the issue of "overcompensation" in scarlet gilia
remains contentious (Belsky 1986, Bergelson and Crawley 1992a, b, Belsky et al.
Now you move through long meadows full of birdsong and bright flowers: gilia
, asters, red-and-yellow columbine, red owl's clover, blue flax, lavender daisics.
caudata, and Ambrosia psilostachya), or a taproot (Chrysopsis villosa, Artemisia campestris, and Gilia
pinnatifida) is further evidence of surface-water shortage (Table 2).
Aside from the pools, Yahi's attractions include a remarkable number of brodiaea species-plus lupines, clarkias, foothill and ftying-pan poppies, Chinese houses, bird's-eye gilia
, shooting stars, delphinium, lomatium, and tarweed, as well as buttercup, monkey flower, and linanthus species.
The Amsinckia populations studied here, which have moderate to very high self-fertilization rates, thus conform to the pattern and can be contrasted, for example, with a highly outcrossing population of the annual Gilia
achilleifolia, in which survival inbreeding depression greatly exceeded that in seed production (Schoen 1983).
Our intent here is to explore these issues, using as our example of morphology the width of the flower corolla tube in scarlet gilia
, lpomopsis aggregata (Polemoniaceae).
A nature trail dawdles along its shore, and at the right time (usually mid- to late July), you'll see wildflowers that range from scarlet gilia
to bluebells to yellow coneflowers.
You might want to bone up on wildflowers, for with any luck you see lots of them this month: gilia
, goldfields, hound's tongue, johnny jump-up, lupine, owl's clover.
We compiled inbreeding depression estimates from plant studies that compared the performance of progeny derived from self- and cross-fertilization (selfed and outcrossed progeny, hereafter) in the greenhouse or common garden or, for some species in which greenhouse estimates were unavailable (e.g., Chamaecrista fasciculata and Gilia
achilleifolia), the field site from which the parents were collected.
For populations of Gilia
achilleifolia, Schoen (1982b) observed a significant correlation between outcrossing rate and protandry but not herkogamy.
