Species Discussions

Acmispon argophyllus and A. heermannii

Allionia incarnata that fooled me. I took the peduncle / flower bracts to be "ternate petioled leaves", and a leaf that curled up at the base when it dried as a "dehisced capsule"!

Allophyllum divaricatum / A. gilioides violaceum

Aphyllon fasciculatum / Orobanche fasciculata / undescribed taxon / A. epigalium / how quickly fleshy parasites disappear

Arctostaphylos glauca / A. glandulosa / A. pungens

Arctostaphylos glauca / A. glandulosa ssp. adamsii

Bahiopsis parishii / Bebbia juncea

Brodiaea elegans / B. terrestris kernensis

Ceanothus foliosus var. foliosus, var. medius, C. austromontanus

Cryptantha barbigera (discussion about nutlets appearing tesselated in some camera pix)

Cylindropuntia bigelovii death rate

Caulanthus lasiophyllus / Streptanthella longirostris / Streptanthus longirostris

Cylindropuntia bigelovii / C. fosbergii

Cylindropuntia bigelovii / C. ganderi

Cylindropuntia ramosissima (discussion about nativity to Borrego Springs area)

Delphinium parishii dead inflorescence comparison to Phacelia minor.

Equisetum x ferrissii

Gilia angelensis / G. clokeyi / G. transmontana

Gilia transmontana / G. ochroleuca exilis

Individual Plants with Multiple Observations from Different Dates

The links are to the first observation for each plant, which contains a list of the follow-up observations.

Calochortus concolor, plants at the turn-out on SR371 north of Anza, followed from 2020 June 8, close to the time of their first blooms, to 19 days later when the blooms were all done.

Ericameria paniculata, two year follow-up in 2018 and 2020.

Malacothamnus fasciculatus, a plant at Coyote Creek First Crossing, washed down from at least 20 miles (35 km) upstream, observed from 2015 December 19 to 2021 January 31, at which time it was long-dead.

Populus fremontii in the San Felipe Valley. Observed over 37 days as their fall color faded, from 2020 December 9 to 2021 January 15.

Stephanomeria diegensis in my Fallbrook yard. It was followed for 12 days to see how long the blooms lasted, and the order in which they bloomed on the main axis. It was then followed long-term after I found that most flowers did not set fruit, due to the lack of nearby other plants to pollinate it. I ended up following the plant to its death, periodically recording the number of flowers open to make a plot of how the bloom declined (the plot is not yet online, nor are the last observations of this plant).
