What would you get if a Mammillaria adapted to hummingbird pollination? You would get a Cochemiea. A typical pincushion flower is a small pink funnel. Imagine elongating that funnel, making it narrowly tubular, and changing the color to bright red. Now you have a Cochemiea (Figure 1).
Cochemiea is a small genus of only five species, all endemic to Baja California. The plants vary from tight clusters of stout stems like a hedgehog cactus (e.g., C. setispina, Figure 2), to long, thin, creeping stems (e.g., C. poselgeri, Figure 3). All five species have clusters of tubular red flowers that are borne at the stem tips following summer rains.
