The location and observation date is intentionally obscured, since this is the only location we've seen this species at San Jacinto Mountain. There were only ten plants seen; this observation, and the following eight, show nine of those plants.

These plants were first spotted by James Dillane in 2007. Dave Stith relocated them in on this trip in 2011.

These are almost surely the same plants as in Jaeger's 1921 voucher from "Tahquitz Ridge - desert side - 9000 feet elevation" (which has an erroneous elevation, since the highest point on Tahquitz Ridge is 8792 feet).

Jaeger's voucher was originally determined as "D. abramsii" by Reid Moran, who cites this voucher as "D. abramsii" in his 1951 Dudleya monograph.

That voucher was redetermined as "D. cymosa aff. ssp. pumila" in 1988. Nakai wrote:


Moran (1951) listed two populations of D. abramsii from the San Jacinto Mountains, one from near Kenworthy [Munz 5788 (POM)] and the other from Taquitz (sic) Ridge, 9000 ft (2770 m) [Jaeger in 1921 (POM)]. The population near Kenworthy is D. abramsii, but differs from typical D. abramsii by lacking the characteristic red striations along the petal midrib.

 

The specimen from Tahquitz Ridge differs considerably from the Kenworthy population in its comparatively broad, oblong to ovate leaves and short floral stem. It resembles no specimens of D. abramsii that I have studied.

...

The status of these populations is uncertain until more material can be studied, but it appears they are not D. abramsii.

Some measurements I made in the field:

rosette width is 3.5 cm.

leaf length x width: 30 x 11; 17 x 5; 12 x 6 mm for the largest leaves. Hence the leaf length is 12 to 30 mm; the leaf width is 5 to 11 mm; and the ratio of width to length is 0.29 to 0.50.

peduncle length is 2.5 to 4.0 cm.

these plants have 1 deg infl branches that are branched zero to one times, although one of the plants in this series of posts might be branched two times.

the # of flowers on each ultimate infl branch is 3 to 4.

pedicel length. This was very hard to measure in the field. I measured the longest at 7 mm, and my pix show some at 4 mm.

i measured just one flower, with sepals of 3.5 mm and petals of 10 mm.

Summary of all my measurements compared to D. abramsii and D. cymosa:

  • 2 fit only D. cymosa (both key characteristics)
  • 1 favors D. cymosa.
  • 1 fits only D. abramsii.
  • 2 favor D. abramsii.
  • 2 don't fit either taxon.
