Asters, Sunflower, Spanish Needle, Sage Brush, Pireweed, 
Thistle, Canada Thistle and Spikeweed. This is a most 
important family from the standpoint of the beekeeper. 
Thoroughwort; see Boneset. 
Tickseed ; see Spanish Needle. 
Tiliaceae ; see Linden family. 
Ti-ti, leatherwood, iron-wood, Cyrilla racemiflora. Evergreen shrub 
to 35 feet, flowers small, white in narrow racemes. May- 
July, February-March in Florida. Honey red, flavor strong, 
good only for baking. Virginia to Florida to Texas, of value 
chiefly in Georgia and Florida. Not a reliable source, as the 
nectar is washed out by rains, which are frequent during 
blooming period in Florida. Precedes tupelo in Appalachicola 
region. Black ti-ti, Cliftonia sp., blooms later and is more 
reliable. 
Tobacco, Nicotina Tabacum. Nectar locally, especially in Con¬ 
necticut, honey fair. 
Tree of heaven ; see Ailanthus. 
Trumpet-creeper family, Bignoniaceoe; see Catalpa and Desert 
Willow.
