描述了巴拿马博卡斯德尔托罗省的一种新种。它是该属中唯一被描述的在萼片上有叶状附属物的第三种。另外两个有萼片附属物的种是萼花B.和结核B.。bocatorena与后两个物种的不同之处在于，它有白色的花瓣和一种花柱与雄蕊相对的雌雄异体花，并形成一个对称的花。在萼萼花和结核花中，较大的花瓣是粉红色的洋红色和具瘤状，雄蕊围绕外露的花柱形成径向对称的花蕊异体花。
The new species Blakea bocatorena is described from Bocas del Toro province in Panama. It is only the third species to be described in the genus that has foliaceous appendages on the sepals. The other two species with these sepal appendages are B. calycosa and B. tuberculata. Blakea bocatorena differs from the latter two species in that it has white petals and a type of herkogamy in which the style is opposite the stamens and results in a zygomorphic flower. In B. calycosa and B. tuberculata, the larger petals are pink-magenta and tuberculate with the stamens encircling the exserted style resulting in a radially symmetric herkogamous flower.
