Boraginaceae (Boraginaceae) is the door of angiosperms, dicotyledonous plants Gang, Ju subclass, the purpose of a lip section. About 100 are more than 2,000 species, distributed in temperate and tropical regions around the world, the Mediterranean region and North America Pacific for the distribution center. 47 are 268 kinds made in China, mainly distributed in the southwest and northwest, a few located in the southeast and northeast. Long grass is a core spot which, if grass is the neck, before the Lithospermum is, if the shield is grass, grass fruit is a micro-endemic to China.

Base and the tree of the Division consists of four subfamilies: ① Cordia wood subfamily (Cordiodeae), including rags, wood is (Cordia). ② Ehretioideae in the subfamily (Ehretioideae), including the tree is a thick shell (Ehretia), round crown wood is (Rotula), the base and the tree is (Carmona), double column Lithospermum is (Coldenia). ③ Boraginaceae (Boraginoideae), including Lithospermum is (Lithospermum), Wolf Lithospermum is (Lycopusis), Microula (Microula), Lappula is (Lappula), attached to food is (Trigonotis), glass grass is (Cynoglosum) and so on. ④ Heliotropioideae (He-tiotropiodeae), including heliotrope is (Hetiotropium), Zidan is (Tournefortia), sand grass is cited (Messerschmidia). Some people claim to the subfamily of wood and rags Ya Keti Ehretioideae out, the establishment of a separate tree branches thick shell (Ehretiaceae).

Economic value
The Division has well-known medicinal plant Lithospermum, early spring wildflowers and grass patches, with ground vegetables, and there has the same efficacy with a soft Lithospermum Lithospermum, etc. Onosma; the feed plant Comfrey; ornamental plant-based and tree (Fukien Tea), bugloss; the oil plant Cordia wood.

The fruit is a drupe with four seed or four separate small nuts. Pollen vary widely. Pollen types are more nearly spherical, prolate or long ball. Size from the smallest forget grass genus Lithospermum is greater than 100 microns in diameter. Pollen often with 3 holes with 3 groove while often false ditch, ditch and sometimes four holes at the same time with 4 false ditch, and multi-channel or multi-channel (Comfrey is). Some, such as tooth edge of the grass pollen grains are two of each trench with bore, and some pollen grains such as Lappula genus Lithospermum is biased towards the groove end of the hole. Pollen spiny surface of a small, fine mesh or granular Glyph. Chromosome number □ = 4 ~ 10 ~ 13. About 100 are more than 2,000 species, distributed in temperate and tropical regions around the world, the Mediterranean region and North America Pacific for the distribution center. 47 are 268 kinds made in China, mainly distributed in the southwest and northwest, a few located in the southeast and northeast.
