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. überführt. 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 PODLECH’s 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.

Peduncles (1–)2–6 in one stem, in the axils of the middle and upper leaves, 1–5 (–6.5) cm long, sulcate, loosely to rather den-sely predominantly black hairy. Racemes short, nearly capitate-umbellate, with 2–7(–9) flowers. Bracts yellowish-membranous to green-ish or later on pale brownish, narrowly ovate to narrowly triangular, acute, (2–)3–7 mm long, sparsely hairy. Pedicels 1.5–3 mm long, densely dark brown hairy. Bracteoles narrowly linear to subulate, 1–7 mm long, at the base of calyx, black hairy. Calyx campanulate, 6–10 mm long, covered loosely to rather densely with appressed dark brown or blackish hairs up to 0.3 mm long, with white hairs mixed in; teeth narrowly triangular or subulate, 3.5–6 mm long, white hairy on inner side. Petals violet to purplish or in basal part yellow. Standard 12.5–16(–17.5) mm long; limb suborbicular, (9–)10–14 mm wide, emargi-nate, gradually or subabruptly narrowed into the wide claw. Wings (10–)11–15(–16) mm long; limbs narrowly oblong to narrowly obovate, rounded or slightly retuse, 9.5–12 × 3.5–5 mm; auricle 1–1.5 mm long, claw 3– 5.5 mm long. Keel (11–)12.5–16 mm long; limbs obliquely obovate, with in upper part widely curved lower edge and ± straight or slightly curved upper edge, obtuse, 9–11(–12) × 4–5.5 mm; auricle 1–1.5 mm long, claw 3.5–6 mm long. Stamen-tube obliquely cut at the mouth. Ovaries with a stipe 1.5–3 mm long, glabrous or white to dark brownish

hairy. Legumes with a stipe 2–3.5 mm long, narrowly ellipsoid, 16–18 mm long, 6–7 mm high and wide, rounded ventrally, deeply grooved dorsally, narrowed into a beak 2–4 mm long, unilocular; valves thin, loosely covered with mostly dark brown, appressed hairs 0.05−0.15 mm long, sometimes glabrescent with age.

Caudex up to 10 mm thick, with a pluricipital root-crown. Stems several, branched at the base, 15–40 cm long, diffusely prostrate to ascending, 1– 1.5 mm thick, in basal parts terete, in upper part angular-sulcate, in basal part glabrous, in upper part sparsely to loosely furnished with spread-ing hairs 0.02–0.25 mm long. Stipules green-ish, 3–4 mm long, narrowly triangular, ciliate at the margins. Leaves 3–5.5 cm long; petiole 0.3–1 cm long, with the rachis slender, sulcate adaxially, hairy like the stem. Leaflets in 5–7 pairs, elliptic, 5–9 × 2.5–5 mm, rounded to retuse, mostly with a minute cusp, on upper side glabrous, on underside loosely covered with tangled, subappressed hairs. Peduncles 3–7 cm long, hairy like the stem. Racemes 2–4-flowered. Bracts whitish-membranous, linear-acute, ca. 4 mm long, ciliate. Pedicels ca. 1 mm long, hairy. Bracteoles narrow, 0.3–1 mm long, at the base of calyx. Calyx cam-panulate, 8–10 mm long, nearly truncate at the mouth, sparsely to loosely hairy; teeth subulate, 4.5–6 mm long. Petals purple. Standard 15–19 mm long; limb suborbicular, 10–13 mm wide, emarginate, subabruptly contracted into the short, cuneate claw.
