Crown of thorns (Euphorbia milii) is a species of flowering plant in the spurge family Euphorbiaceae.. It is a wood succulent shrub native to Madagascar. 

The genus name, Euphorbia, honors the Greek physician, Euphorbus (52 B.C. - 23 A.D.).The specific epithet honors Baron Milius, one-time Governor of the island of Bourbon, who reportedly introduced this species to cultivation in France in 1821.Botanical illustrations are available to easily identify a species of interest through The Biodiversity Library.The Biodiversity Library is searchable not only by author and title but chronologically by date, collection, and contributor. I have chosen the Madagascar Native, Euphorbia Milili, to feature below.

Flame of Jamaica | Euphorbia Punicea

Flame of Jamaica

1. On a stroll through the San Antonio Botanical Garden Conservatory the tropical Euphorbia was showing a lovely bloom. If you think this plant looks a lot like the poinsettia there is good reason. The poinsettia, which is a commercially important plant sold during the Christmas season, belongs to a diverse plant family, the spurges. The poinsettias  are indigenous to Mexico and the flame of Jamaica is indigenous to the Caribbean Island of Jamaica. The yellow portion of the plant is the flower and the red portions are bracts. 

Flame of Jamaica, a lovely relative of the poinsettia, is an evergreen, almost ever-blooming shrub native only to that Caribbean island. Known in the tropics as Jamaican poinsettia, established specimens are fairly drought tolerant but benefit from irrigation during hot, dry periods in spring and autumn. Planting sites must be well drained and — because flame of Jamaica is as tender to cold as the poinsettia — shielded from north and northwest winds. 

The flame of Jamaica was first described by Olof Peter Swartz in his Nova genera et species plantarum seu prodromus.
