Etymology: "Chlorocardium" is a botanical genus name, not an ordinary English word, and it was coined by taking Greek roots and joining them into a new compound. "Chloro-" comes from Greek "khlōros", meaning pale green or greenish-yellow, the same root behind "chlorophyll" and "chlorine". "Cardium" is Latin for heart, borrowed from Greek "kardia", which also gives English words like "cardiac". Put together, the name describes a plant with a green heart, a reference to the colour of its inner tissue or foliage. The genus is a member of the laurel family (Lauraceae), and like most plant genus names it was formally published by botanists under the international rules of plant nomenclature, which allow scientists to build new Latinised names from classical roots. Its exact date of publication and the detailed reasoning of its describer are beyond what I can confirm here, so the meaning given above reflects the standard construction of the name rather than a documented account from its author.
