Jacaranda caerulea (boxwood or cancertree) is a flowering tree belonging to the genus Jacaranda. It is native to the West Indies, including Cuba and the Bahamas.[1][2]

Description

Jacaranda caerula was described in 1805 by French naturalist Jean Henri Jaume Saint-Hilaire.[3] It grows up to 12 metres (39 ft) in height and has 40 cm long, bipinnate leaves each with 8 to 26 pinna.[4]

The flowers are purplish blue in colour with a tubular shape, being narrower towards the base and larger at the tip. They measure 3.5 to 4 cm long and 1 to 1.4 cm wide at the mouth.[4] It flowers intermittently throughout spring and summer, rather than having one big bloom during spring.[2]
Distribution

The tree is native to the Bahamas and Cuba, but can also be found in Florida where it was introduced for landscaping purposes.[2] It most commonly found in limestone areas between sea level and 300m.[4]
Uses

The leaves are used in some places for their antiseptic properties. In the Bahamas, decoctions are made from the dried leaves and used as an alternative treatment for a variety of skin complaints, including skin cancer. In Cuba, decoctions of leafy branches are used to treat eczema and acne.[5]
