Observation on Chromosomes of Wildflowers in China

In this paper 7 species of wildflowers were collected from Beijing suburb and Jilin Province. They are all common sightly and hardy perennials in their localities (See the Appendix for detail of the materials). The micrographs of their somatic metaphases are shown in Plate 1; the karyotype formulae, ranges of chromosome length and classification of karyotypes according to Stebbins (1971) are shown in Table 1; the idiograms of 5 species in Figs. 1-5. The karyotype analysis is made on the basis of Li and Chen (1985)⁽¹⁾. The essential points are as follows; (1) Ten pairs of chromosomes of Achyrophorus ciliatus are all submetacentric (sm). (2) Twelve pairs of chromosomes are all metacentric (m), and the short arms of the seventh pair of chromosomes with a pair of satellites in Orychophragmus violaceus. (3) The seventh and nineth pairs of chromosomes are sm and the short arms of latter with satellites in Silene repens var. angustifolia. It is reported for the first time. (4) In Scabiosa tschiliensis. the first, fourth, fifth and eighth pairs of chromosomes are sm, the sixth is terminal (t). The second and seventh are subterminal (st), the third is m. There are satellites on the short arms of third and seventh pairs. It is reported for the first time. (5) The eleventh pair of chromosomes is sm and the others are all m. The short arms of the twelfth pairs with satellites in Lychnis fulgens. (6) The chromosome number (2n) is 42, with a pair of satellites in Papaver pseudo-radicatum. It is also reported for the first time. (7) The chromosome number is2n=56 with two pairs of satellites in Rehmannia glutinosa.

Devonian antiarchs (Pisces,Antiarchi) from central and Southern European Russia

Antiarchi (Pisces, Placodermi) from the Devonian of central and southern European Russia (Central Devonian Field) are studied. Antiarchs belong to three families, the Asterolepididae, Remigolepididae (suborder Asterolepidoidei), and Bothriolepididae (suborder Bothriolepidoidei). The diagnoses of the order, two suborders, three families, and five genera (two of which are new) are given. Sixteen species, including one new, are described; ten taxa are determined in open nomenclature. Morphological structures of representatives of these families are considered in detail. Classifications of antiarchs and their position in the system of the lower vertebrates are discussed. Devonian vertebrate localities of central and southern European Russia that have yielded antiarchs are listed. Each locality is characterized by its ichthyoassemblage.

A taxonomic revision of the genera Phrygionis Hübner and Pityeja Walker (Geometridae: Ennominae, Palyadini)

Phrygionis and Pityeja belong to the Palyadini, a tribe of neotropical Ennominae. The moths of both genera bear striking wing markings and mere variants were frequently described as species with the consequence that species diversity was overestimated. Numerous taxonomic changes are made in this work based on the study of primary types and much other material. Variation and distribution is recorded for each species and subspecies. Phylogenetic relationships within Phrygionis are examined, and comments are made on the evolution of wing pattern within this genus.
Fifteen full species are recognized in this study (13 in Phrygionis and two in Pityeja ), of which four (all in Phrygionis ) are described as new; 19 species-group (specific and subspecific) names refer to valid taxa. Twenty-four species-group names are synonymized (19 in Phrygionis and five in Pityeja ) and five are recombined with different genera (four with Phrygionis and one with Pityeja ). Three generic names are synonymized (one in Phrygionis and two in Pityeja ).     

Studies on the Genus Paeonia (1)—Report of Karyotypes of Some Wild Species in China

In the present paper 8 species with 15 populations of the genus Paeonia L. (if P. papaveracea and P. japonica are recognised as species) were collected from Sichuan, Shaanxi and Hebei provinces (see the Appendix for detail of the materials). The micrographs of their somatic metaphase (also Mii in the case of P.veitchii) are shown in Plates 1-4, the karyotype formulae, ranges of chromosome length and classification of karyotypes according to Stebbins (1971) are shown in Table 5: the idiograms in Figs. 1-2, and the parameters of chromosomes in Table 1-4. The essential points are mentioned as follows: (1) Chromosomes of the various species in the section Modan have so far been examined and they are all diploid, the two species in the section Onaepia are also diploid, and thus tetraploids exist only in the section Paeonia. (2) Chromosomes in the genus Paeonia are relatively stable except for the differentiation of ploidy. The karyotypes (Table 1-4) show no differences among different taxa in Sect. Modan and the same can also be said about the taxa in Sect. Paeonia (Table 1). Not only are the karyotypes very similar, but also among the members within either section have the same parameters of chromosomes, and, differences, if occur, are not statistically significant. Between the two sections, however, the situation is different. The arm ratios of the first pairs of chromosomes in Sect. Modan are 1.53, 1.52 and 1.48 (Table 1), but those in Sect. Paeonia are 1.12-1.28 (Table 2-4), 95% confidence limits are 1.46-1.60 for the section Modan and 1.07-1.28 (1.21-1.35 only for PB85078) for the section Paeonia, not overlapping, which indicates that the two sections have differentiated in respect of the first pairs of chromosomes. (3)The population PB85024, which belongs to the P. obovata complex, has a karyotype of 2B (stebbins, 1971), which is a new one in the genus Paeonia. This karyotype is a stable one, for several individuals in the population are uniform in this respect, which shows that Stebbins’ (1971) generalization that all the species in Paeonia have 2A does not hold true. (4) Three populations of P. obovata complex studied in this work from Sichuan and Shaanxi are all tetraploids, and one from Hebei is a diploid. From the present work and the previcus reports, the materials from Japan and Korea, no matter whether flowers are pink or white, are diploids, those from Heilongjiang Province (with both pink and white flowers) (Liu Ming-yuan, personal communication) and from Heibei Province (with pink flowers) in China are also diploids, the one from Sakhalin (pink flowers) is tetraploid, those from Priamur of the Soviet Union are a tetraploid (with white flowers) and a diploid (with pink flowers), and those from Shaanxi (the Qinling Range) and western Sichuan (with both pink and white flowers) are all tetraploids. As far as we have now known, ploidy in this particular complex is correlated with the geographical distribution: diploids are found in the central part, tetraploids occur in the northern limits, and in the south letraploids are the only cytotype. (5) The materials of P. mairei from western Sichuan and Shaanxi (the Qinling Range) are found all to be tetraploids, which shows that two cytotypes, diploid and tetraploid, exist in this species, but the geographical distribution pattern of these two cytotypes is to be revealed in the future investigation.
