The New American Standard Bible (NASB) says “bulb” or possibly a “calyx” (plural: calyxes or calyces). A calyx is “the sepals of a flower, typically forming a whorl that encloses the petals and forms a protective layer around a flower in bud.”
“Then you shall make a lampstand of pure gold. The lampstand and its base and its shaft are to be made of hammered work; its cups, its bulbs and its flowers shall be of one piece with it. Six branches shall go out from its sides; three branches of the lampstand from its one side and three branches of the lampstand from its other side. Three cups shall be shaped like almond blossoms in the one branch, a bulb and a flower, and three cups shaped like almond blossoms in the other branch, a bulb and a flower—so for six branches going out from the lampstand; and in the lampstand four cups shaped like almond blossoms, its bulbs and its flowers. A bulb shall be under the first pair of branches coming out of it, and a bulb under the second pair of branches coming out of it, and a bulb under the third pair of branches coming out of it, for the six branches coming out of the lampstand. Their bulbs and their branches shall be of one piece with it; all of it shall be one piece of hammered work of pure gold.” —Exodus 25:31-36 NASB
