Flora of Queen Mountain Area, Joshua Tree National Park

This is a preliminary, working list of the flora of this area, compiled primarily from vouchers retrieved from a search of the Consortium of California Herbaria on 20 November 2011, augmented by species recalled from memory, or present in my pictures, from an entirely hiking trip on 18 November 2011.

This area was very dry on the hiking trip, with the plants in their typical late summer mostly-dead-looking form. The only sign of recent rain was a few holes on the top that held water. I dug in the wash down below without finding any moistness at all. The only species in bloom were a very few plants of Eriogonum inflatum.

Nonetheless, this is a pretty spectacular area, with slopes covered with Opuntia chlorotica and Yucca schidigera, the densest collection I've ever seen of these two species.

The following pictures show how dry the area was during this hike, and how beautiful some of the slopes are. Click on the thumbnails to get larger versions of each picture.

The vouchers were taken mostly at face value. Be aware that some of them are likely misdetermined. Since I have almost no familiarity at all with the flora of this area, it is difficult for me to know which taxa are obviously misdetermined.

No time was spent to identify plants securely on the hiking trip. Many of the determinations were just taken to be the likely one, based on the voucher list. It is quite possible that some of my "determinations from memory of a fleeting glimpse" are incorrect. Some of the species were added from the original versions of the panoramic pictures above; sometimes this can be problematic.

Hence the following caveat should be taken quite seriously:

This is a working list, about which I make no guarantees at all. Use at your own risk!

This Checklist is almost surely quite incomplete, since lists compiled from the random vouchering process are almost always incomplete. A glance at the list below shows that some common species observed on the hiking trip, such as creosote, Larrea tridentata, are missing from the voucher list.

The vouchers were obtained by a geographic search of the area from 33.98° to 34.08° north latitude, and -116.26° to -116.05° east longitude, augmented by four non-georeferenced vouchers with locality of Queen Mountain or Queen Valley. The locality field was examined, and vouchers not from this area were tossed. Taxa determined only to the species were assigned to a vouchered subspecies if that was the only subspecies vouchered in this area. One voucher taxon, of Chrysopsis villosa var. hispida, was ignored since it was almost surely misdetermined, and I had no idea of its likely true determination.

The coordinates of the vouchers are shown as the filled red squares on the following map, provided by the Consortium of California Herbaria:

The search area is not centered on Queen Mountain in order to include the highest nearby mountain area, Quail Mountain. At 5813 feet elevation, its summit is just slightly higher than the 5687 foot Queen Mountain, and my guess was that the species would be more similar there than extending the search box to the east to Twentynine Palms Mountain, whose highest point is 4562 feet.

The hiking trip was from the O'Dell Parking Area to the west summit of Queen Mountain, shown in pink on the above map, from 4450 to 5650 feet elevation. I recalled or photographed 54 taxa, of which 16, 30%, were not in the voucher list.

The total list contains 249 taxa, 233 taxa from vouchers plus 16 taxa from the hiking trip.

The Checklist is sorted first by category - ferns, dicots, and monocots - and then by family and scientific name. The JM Family and Scientific Name are from the 1993 first edition Jepson Manual. An asterisk before the Common Name indicates a non-native taxon.

The column #Pls gives the minimum number of plants I recall seeing, up to a maximum number given of 99.

The column #Vch gives the number of vouchers for each taxon.
