The inflorescence type where flowers are in clusters of 3 and the middle flower is the most mature one is:

cyme

Woody plants with alternate, simple leaves with asymmetrical leaf bases. Flowers small, with 4 to 9 green tepals and 2 carpels (in female flowers). Wood with long fibers, making it very bendable. Fruit type often a samara.

ulmaceae

Mostly herbaceous flowering plants with usually compound (often ternate) leaves, and many stamens. Flower parts otherwise in fives or variable. Fruit type often an aggregate of achenes or follicles. No hypanthium. Some of them are known for their yellow color.

hyperiaceae

Umbrella family of woody plants with alternate or opposite, simple or compound leaves and often small, 4- or 5-merous flowers. 2-3 carpels; genera include some with double-samaras and some with capsules with large seeds with “eyespots.”

sapindaceae

Family of monoecious submerged aquatics with whorled, dichotomously splitting, filamentous leaves and very small flowers. Fruit type is a spiny achene.

certatophyllaceae

Family of plants with milky sap. Usually, the inflorescence is a cyathium—consisting of separate male and female flowers and some nectaries. The ovary is three-lobed and becomes a schizocarpic capsule at maturity.

euphorbiaceae

Family of mostly herbs in our area with opposite or sometimes alternate leaves. If simple, leaves are usually palmate and roundish. Flowers with all parts in 5’s. Ovary splits apart into 5 sections (a schizocarp). The developing fruit usually has a long, distinctive

ranunculaceae

Woody plant family with alternate, simple leaves and no stipules. Wood, twigs and leaves are fragrant. Flowers are small with sepals, petals and stamens in multiples of 3 and one carpel. Fruit type is a drupe. Anthers have valvate dehiscence.

lauraceae

Family of herbs and woody plants with showy flowers and alternate, palmately veined leaves. Flowers usually with 5 sepals and petals, many stamens in a tube with anthers branching off, and 5 stigmas branching up out of the center of the stamen tube. Fruit type a capsule with hairy seeds.
