Pineland Spurge Euphorbia pinetorum
Pineland Spurge is a perennial wildflower native to the lower 48 states. A host for pollen-specialist native bees.
More about this plant
Euphorbia deltoidea, also called wedge sandmat, is a species of flowering plant endemic to Florida in the United States. The taxonomy of the plant is difficult, with some authorities dividing it into four subspecies and some into three; also, it is frequently listed as a member of the old genus Chamaesyce. One subspecies, ssp. deltoidea, is a federally listed endangered species called deltoid spurge. It is found only in Miami-Dade County. Another subspecies, ssp. adhaerens, is often included with it under the name deltoidea instead of separately, making it difficult to keep count of how many endangered plants there are. This is generally dealt with by placing the "endangered species" label on any taxon within the species that is limited to Miami-Dade County, however many names they may have. Wikipedia →

Wildlife & pollinators
How pollinator value is scored →❧ Caterpillar hosts ~7 caterpillar species
Euphorbia supports ~7 caterpillar species.
Native butterfly & moth caterpillars are the base of the terrestrial food web — most songbirds rear their young almost entirely on them. As a host for native Lepidoptera this is a modest genus.

✦ Bees specialist-bee host
Specialist native bees depend on it.
Some native bees are pollen specialists (oligolectic) — they raise young only on pollen from particular plant genera. Euphorbia is a recorded specialist-bee host, so losing it can mean losing the bee that relies on it.

How we know this (1) Methods & honest limits
McKenzie et al. assigned each species a flower colour with a GPT-4V vision model over iNaturalist photos. We use the confident tier plus a separately-labelled lower-confidence top-up (mostly inconspicuous green/brown flowers), and render it as a small tint — never as an asserted fact, and kept out of the written synopsis.
Honest limits: AI image inference (~87% expert agreement on the confident tier); a decorative, confidence-tiered indicator, not a measured trait.
