    Revision of the Genus Phyllolobium FISCH. (Leguminosae-Papilionoideae)

    Summary According to the most recent molecular and pollen evidences, Astragalus L. subgenus Pogonophace is proposed to be extracted from Astragalus and erected as a new genus Phyllolobium FISCH. Based mainly on the specimens checking of major Chinese herbaria, a taxonomic revision regarding this genus is provided in the present paper. 1. Phyllolobium balfourianum (N.D.SIMPSON)

    Zusammenfassung

    Revision der Gattung Phyllobium FISCH. (Le-guminosae-Papilionoideae)

    Entsprechend moderner molekularer und pollenmor-phologischer Daten wird Astragalus L. subgenus Pogonophace aus der Gattung Astragalus ausgeglie-dert und in eine eigene Gattung Phyllolobium FISCH. berfhrt. Basierend auf dem reichen Material, vorwiegend in den grossen chinesischen Herbarien, wird eine Revision dieser Gattung vorgelegt.

    Astragalus L. subgenus Pogonophace was established by BUNGE (1867) mainly based on a distinct character, the penicillately hairy stigma. Molecular analysis based on the ITS sequence (KANG et al. 2003) has shown that the subgenus is not a monophyletic taxon. Mean-while, the same character was observed from species among several other sections of the genus Astragalus, these sections are not mem-bers of subgenus Pogonophace, i.e., annual: Hispiduli, Annulares (PODLECH 1994); per-ennial: Erionotus (PODLECH 1988). BAKER (1876) described a new subgenus in the genus Astragalus, subgenus Trichostylus BAKER, which was based on the character of the style with hairs on the dorsal side below the stigma. In this subgenus, the species A. heydei BAKER has been thought of having the charac-ter of penicillately hairy stigma. But the posi-tion of these hairs at the style is not constant and even missing in many flowers of this spe-cies. Furthermore, this character can be found commonly in other sections of Astragalus, such as sections Caprini, Astragalus, Aegacantha and Pelta. Therefore, penicillately hairy stigma should not be thought to be a synapomorphic, but a parapomorphic or polymorphic character among the groups mentioned above, which should not be used as diagnostic character in the higher rank among these taxa. As a single character regarding the penicil-lately hairy stigma, it should be considered as having heterogenous origin. In some groups within subgenus Pogonophace we can find in-teresting pollen brush hairs (KANG & ZHANG 2004), those groups include the sections Bibrac-teolati, Phyllolobium and Trichostylus. Com-bined with the characters of non-interlocking keel and wing petals (for the absence of bosses on the keel and matching sockets on the wings), these sections form a very natural group and are similar to the genera which are clearly belonging to subtribe Coluteinae BENTH. & HOOK. f. instead to Astragalus (belonging to subtribe Astragalinae BENTH. & HOOK.f.).

    BARNEBY (1964) was the first, who found the strong similarities between Astragalus complanatus and the genera Sphaerophysa and Swainsonia of subtribe Coluteinae. However, those species only with hairy stigma but with-out the pollen brush, such as Astragalus ho-antchy FRANCH. belonging to former Pogono-phace, have interlocking Keel and wing petals, therefore they belong clearly to the genus As-tragalus. KANG & ZHANG (2004) proposed that those species with pollen brush hairs should be clas-sified as a new genus Phyllolobium, which was created by FISCHER in 1818 with the type spe-cies later named as Astragalus complanatus. During PODLECHs stay in China this year, the important characters of all species of sect. Bi-bracteolati and the related ones have been investigated once more. Combined with our previous studies (ZHANG 2000, 2002; KANG & ZHANG 2004), it is quite clear that all species of the sections Phyllolobium, Bibracteolati and Trichostylus form a natural group, namely the genus Phyllolobium FISCH. These species occur mainly in the southwestern high mountains of China (ZHANG 2003). A taxonomic revision of all species of this genus is given as follows.
