In all cases reported to date, the pigments shown to be responsible for floral UV absorption have been fla­ vonoids (Thompson et al. 1972; Brehm and Krell 1975; Scogin and Zakar 1976). A recent report on the reproductive biology of Crossosomataceae noted two apparently inconsistent features: 1) low petal UV reflectance (less than 5%) and 2) the notable lack of detectable petal flavonoids (Scogin and Tatsuno 1982). These results raised the question of what pigment was ac­ complishing the UV absorption in Crossosoma petals, which is addressed in the
