Question: The Golden Buckeye Program, which takes its name from the tree species Aesculus glabra, is a free service of what state?

Context paragraphs:
Buckeye chicken: The Buckeye is a breed of chicken originating in the U.S. state of Ohio.  Created in the late 19th century, Buckeyes are the only American Poultry Association (APA) standard breed of chicken known to have been created by a woman, and the only one in the American Class to have a pea comb.  As of 2014, Buckeyes are listed as "Threatened" by The Livestock Conservancy.  The breed's name is derived from Ohio's nickname of "Buckeye state", and their mahogany color is said ideally to resemble the seeds of the Ohio Buckeye plant ("Aesculus glabra").  They are a dual-purpose chicken that have a decent laying ability and strong meat production characteristics.  Buckeyes are yellow skinned chickens that lay brown eggs.

Aesculus parviflora: Aesculus parviflora (bottlebrush buckeye) is a species of "buckeye."  It is also called "dwarf horse chestnut" in recognition of its resemblance to its more famous relative "horsechestnut".  The species is native to open woodlands of the southeastern United States (primarily Alabama with additional populations in Georgia and Alabama).  It is apparently naturalized in scattered locations in North Carolina, New York, Pennsylvania, and New Jersey.

Aesculus × carnea: Aesculus" × "carnea, or red horse-chestnut, is an artificial hybrid between "A. pavia" (red buckeye) and "A. hippocastanum" (horse-chestnut).  The origin of the tree is not known, but it probably first appeared in Germany before 1820.  The hybrid is a medium-size tree to 20–25 m tall, intermediate between the parent species in most respects, but inheriting the red flower color from "A. pavia".  It is a popular tree in large gardens and parks.

Janzen–Connell hypothesis: The Janzen–Connell hypothesis is a widely accepted explanation for the maintenance of tree species biodiversity in tropical rainforests.  It was published independently in the early 1970s by Daniel Janzen and Joseph Connell.  According to their hypothesis, host-specific herbivores, pathogens, or other natural enemies (often referred to as predators) make the areas near a parent tree (the seed producing tree) inhospitable for the survival of seedlings.  These natural enemies are referred to as 'distance-responsive predators' if they kill seeds or seedlings near the parent tree, or 'density-dependent predators' if they kill seeds or seedlings where they are most abundant (which is typically near the parent tree).  Such predators can prevent any one species from dominating the landscape, because if that species is too common, there will be few safe places for its seedlings to survive.  However, because the predators are host-specific (also called specialists), they will not harm other tree species.  As a result, if a species becomes very rare, then more predator-free areas will become available, giving that species' seedlings a competitive advantage.  This negative feedback allows the tree species to coexist, and can be classified as a stabilizing mechanism.

Aesculus glabra: The tree species Aesculus glabra is commonly known as Ohio buckeye, American buckeye, or fetid buckeye.  Glabra is one of 13–19 species of Aesculus also called horse chestnuts.

Aesculus flava: Aesculus flava, the yellow buckeye, common buckeye, sweet buckeye, or colloquially as "sweet chestnut" in the United Kingdom, to some confusion is a species of deciduous tree.  It is native to the Ohio Valley and Appalachian Mountains of the Eastern United States.  It grows in mesophytic forest or floodplains, generally in acid to circumneutral soil, reaching a height of 20m to 47m.

Aesculus: The genus Aesculus ( or ), with varieties called buckeye and horse chestnut, comprises 13–19 species of flowering plants in the soapberry and lychee family Sapindaceae.  They are trees and shrubs native to the temperate Northern Hemisphere, with six species native to North America and seven to 13 species native to Eurasia.  Also, several hybrids occur.  "Aesculus" exhibits a classical arcto-Tertiary distribution.

Aesculus chinensis: Aesculus chinensis, the Chinese horse chestnut (Chinese:七叶树 qi ye shu), is a tree species in the genus "Aesculus" found in eastern Asia.

Golden Buckeye: The Golden Buckeye program is a free service of the Ohio Department of Aging.  Ohio citizens age 60 and over automatically qualify for membership in the program and receive a Golden Buckeye card in the mail.  Adults age 18 to 59 years old with disabilities as defined by Social Security also qualify for the card and can apply for one at most Ohio senior centers and public libraries.  This well-known program has been in place since 1976 and entitles cardholders to discounts on purchases at participating Ohio merchants.  The current Golden Buckeye card includes the Ohio's Best Rx prescription drug discount program on its back side.

Tecomella: Tecomella undulata is a tree species, locally known as rohida in Urdu "روہیڑا" found in Thar Desert regions of India and Pakistan.  It is a medium-sized tree that produces quality timber and is the main source of timber amongst the indigenous tree species of desert regions of Shekhawati and Marwar in Rajasthan.  The trade name of the tree species is desert teak or Marwar teak.
