The classification of the Papaver species from North-east China wasrevised. The concept of classificatory features of the basic form of thespecies, P. nudicaule L., was expanded-sensu ampl., including those planstswho have yellow, pale-yellow and orange flowers. The concept of the sup-species, P. nudicaule L. subsp. amurense N. Busch., was narrowed-sensustr., only refering to the plants with white flower and glabrous fruit.Those plants who have orange flower were classified into the subsp. nudi-caule. Two new varieties of the species were described, var. glabricarpum and subsp. amurense N. Busch. var. seticarpum. The new key to the genusspecies from North-east China was made.

There are 240 species of 46 genera of Labiatae in Hergduan Mts.,Its species amount is less than that of Yunnan and Sichuan, but muchmore than that of Xizang and other provinces in China. After analysingthe distribution of genera and species of Labiatae in Hengduan Mts., weknow the characteristics of the geographical distribution of Labiatae inthis region as follow:i. The distribution-type of genera is mainly oftemperate nature, having a percentage of 85.3% of total genera. (Thecosmopolitan genera are excluded from the total and from the calculationof the other statics.) Among temperate distributron-type, that of Eastern Asia (mainly of Sino-Himalava subtype) has a percentage 34.1% of totalgeneral and that of Old World temerate and North temperate has a percen-tyge of 29.2% and 12.2% of total genera respectively. ii.The distribution-tupe of species is mainly of endemic in China, having a perceutage of 75%of total species. But that of temperate and tropical only have a percentageof 20% and 5% of total species respectively. Among endemic spceis in Chinaabout a percentage of 72.8% is of endemic in Hengduan Mts. The areaof NW Yunnan and SW Sichuan is a most important center of endemieSpecies is Hengduan Mts. It posscss a percentage of 67.2% of total ende-mic species in Hengduan Mts. iii. The origin cause of endemic species imthe area of NW Yunnan and SW Sichuan is mainly of ecological reasonrather than historical reason.

Pollen grains of 17 species and 1 variety of the genus Adonis in Ranun-culaceae distributed in China, Japan and Europe were examined by LM andSEM. Adonis po11en can be divided into 2 types according to characters ofthe aperture and the exine. They are as follows:Type 1. Two poles of exine not thickened. Margin of colpi irregularand not thickened. Surface of exine undulate or rough. (Sect. Consiligo) Type 2. Two poles of exine distinctly thickened. Margin of colpe reg-ular and thickened. Surface of exine nearly plane. (Sect. Adonis) These types are identical with the two sections, perenaial Sect. Consi-ligo and annual Sect. Adonis, which were described based on morphology.In the meantime, variation of pollen morphology in the genus is found onlyin Sect. Consiligo (Pollen type 1), and it can be divided into 4 subtypesbased on forms of pollen porferation and exine ornamentation. They are asfollows:Subtype 1:Porferations indistinct, spinules biger and longer. (A. brev-istyla) Subtype 2:Porferations major and pores arrangment irregular. (A. ver-nalis, A. pseudoamurensis, A. wolgensis). Subtype 3:Porferations minor and pores scattered. (A. bobroviana, A.sutchuenensis, A. coerulea, A. chrysocyatha, A. sibirica, A. villosus) Subtype 4:Porferations minor aod pores arranging in rows. (A. amuren-sis, A. dahurica, A. romosa) According to comparative study of polynology and morphology the pre-sent author consideres that A. brevistyla might be primitive and A. chrysocy-atha representing a blind branch in Sect. Consiligo.
