Leaf blade 5-11-foliolate; leaflet blades without scattered, conspicuous glands, margin crenate to serrate or compoundly so. Thyrse cylindric or conic; branches simple; bracts absent. Flowers often large and showy. Sepals connate to form a tubular to campanulate calyx tube. Petals often unequal, base clawed, limb obovate, oblong, oblanceolate, or spatulate. Ovary without a gynophore; style long, slender; stigma depressed globose, entire or obscurely lobed. Capsule depressed globose to pyriform, without a long gynophore, often 1-seeded; pericarp usually smooth, often dotted, rarely verrucose or prickly. Seeds depressed globose to pyriform, large (2-7 cm) ; testa brown; hilum large, pale, occupying 1/3-1/2 of seed. x = 20.^[1] [more]

At least 224 species and subspecies belong to the Genus Aesculus.

Agalinis

Agalinis Raf. (false foxglove) is a genus of about 70 individuals that until recently was aligned with members of the family Scrophulariaceae. As a result of numerous molecular phylogenetic studies based on various chloroplast DNA (cpDNA) loci, it was shown to be more closely related to members of the Orobanchaceae. Agalinis spp. are hemiparasitic, which is a character that in part describes the Orobanchaceae. [more]

At least 102 species and subspecies belong to the Genus Agalinis.
