Here's my preliminary target list of plants to hunt this year:
Astragalus feensis (Santa Fe Milkvetch) — April–June, 5100-6000 ft
Dalea scariosa (La Jolla Prairie Clover) — August–September, 4750-4900 ft (D*)
Delphinium sapellonis (Sapello Canyon Larkspur) — July–September, 8000-11,500 (D*)
Heuchera pulchella (Sandia Mountain Alum-Root) — July–September, 8000-10,700
Mentzelia todiltoensis (Todilto Stickleaf) — June–September, 5600-5840 ft
Muhlenbergia arsenei (Navajo Muhly) — August–September, 4600-6500 ft (D*)
Physaria iveyana (Sandia Mountain Bladderpod) — May–June, North Sandia Crest
Sclerocactus papyracanthus (Grama Grass Cactus) — April–June, above Placitas (D*)
Silene plankii (Plank's Catchfly) — July–September, 5000-9200 ft
Spiranthes magnicamporum (Great Plains Lady's Tresses) — mid-July–August, 4560-6500 ft (D*)
Although a number have been dropped from the NMRPTC strategy list (D* above), they have been listed by at least one agency at one time.
As for a schedule, Astragalus and Sclerocactus get going in April. Physaria kicks in later in May. Mentzelia begins blooming in June, followed by Delpinium, Heuchera, Silene, and Sprianthes in July. Dalea and Muhlenbergia round out this list of ten species.
While July looks to be the peak month for plant hunting, I'll also be chasing Aphyllon up in Rio Ariba County. Busy times ahead!
