Four New Species of Dragon’s Blood Croton (Euphorbiaceae) from South America

We describe and illustrate four new species of dragon’s blood trees (Croton sect. Cyclostigma) fromwestern SouthAmerica. Three of the species, Croton beckii from Bolivia and Peru, C. camposii fromPeru, and C. santamartensis fromColombia, grow inmontane Andean forest,whereas C. tumbesinus occurs in d...
