Bitter Tesco (Gesneriaceae)

1st Department of the Gemin leaf plant,
Of
Yagang.mostly herbs with roots and a few are shrubs or trees. Leaf-to-birth or base-based, thin-wheeled or mutual-born, usually single-leaf, not divided, thin feather-like split or feather-like re-leaf. Flowers usually make up the sequence of umbrella flowers, both sexes, radiation symmetry or left and right symmetry. Tablets

Collumnea
,
Asterantherath
) by the native American hummingbird pollination, Asia's tropical mango moss with similar flower crowns, also by the bird pollination. There are

species in China, from the southwest, north and south of China to Hebei, southwest Liaoning, mostly distributed in southern China and southeastern Yunnan karst areas, there are

The flowers of many of the plants are beautiful for viewing, famous for their large rock genus, African purple barite genus, Cape of Good Hope moss genus, mango moss genus and European moss genus. Chinese-made stone hanging orchids, cow ears, grasshoppers seven, cat ears, dragon grass and so on in the folk for medicinal purposes.undergraduate and mainly distributed in the temper zone of the basalt is very similar, the latter's sub-room

room, there is a central axis tire seat, can be distinguished (but a few of the undergraduate genus also has a central axis fetal seat). Undergraduates are also very similar to Lydenko (sub-room side membrane fetal seats), but the latter is a parasitic plant free of cophyte.evolutionary trend:(1) leaf pair to each other, not split to split, single leaf to compound leaf; (2) flower radiation symmetry to left and right symmetry; (3) slivers to healing, flower radiation symmetry to left and right symmetry; (2) flower radiation symmetry to left and right symmetry; 4) Corolla radiation symmetry, males can all breed (spoke moss genus) , to the corolla about symmetry, male

yako:bitter Tayaco sub-leaf after germination becomes unequally large, sub-room upper position. It is mainly distributed in southern and southeastern Asia, southern, western and eastern Africa, and a few in southern Europe and Oceania. The flower radiation symmetry of the bitter moss people, the males are all able to breed, is the original group of Ben yako, there are

genus. The flowers
the
4 ethnic groups are symmetrical from left to right, and the males have

degradation. Themoss family withfruit and no appendages is the largest family of bitter moss, about
55
genus. The man-haired moss family is approximately long but the seeds are protruding at both ends and often form woolly appendages, with

genus. The tip-tongue moss family is also similar to the long moss family, but the same pair of stems and leaves are often very large, or leaves are born to each other, sub-room ovum or spherical, there are
9
genus. The berry moss is characterized by fruit that does not crack, meaty or shelly, and has

genus.large rock yakoleaves after germination and so on, the sub-room is mostly semi-lower or completely sub-lower, a few upper positions. Mainly distributed in South America and Mexico, a small number of Oceania. A small number of primitive genus (such as
Depanthus
) of the flower radiation symmetry, males are all able to breed, sub-room upper position, the vast majority of the genus of flowers left and right symmetry, males have
