 (Sims) Makino, the Chinese Wisteria.

Subtribe 3. BRONGNIARTIANAE. Trees or shrubs, with alternate odd- 

 pinnate leaves ; stipules and sometimes stipels present, the former often caducous 

 and the latter minute. Flowers axillary or in terminal racemes or panicles. 

 Calyx with a short tube, more or less 2-lipped, the upper two calyx-lobes united 

 high up or to the apex, the lower three also more or less united. Corolla papili- 

 onaceous, the banner broad and with somewhat reflexed or spreading sides. 

 Stamens monadelphous or diadelphous; anthers various but not appendaged. 

 Pod usually elongate, flat, 2-valved, several-seeded, sometimes filled between 

 the seeds with spongiose tissue. Seeds erect, i.e., the longer axis at right angles 

 to the pod, somewhat compressed, with a well developed strophiole. 



Calyx 5-Iobed, the upper 2 lobes united two-thirds to four-fifths their length, 

 the lower 3 usually free to near the base, but sometimes united higher up; 

 stamens diadelphous (9 and 1), the filament of the uppermost one free; 

 leaves never glandular-granuliferous beneath. 5. Brongniartia. 



Calyx completely 2-lipped, the upper 2 as well as the lower 3 lobes united to the 

 apex; stamens monadelphous, the filament of the upper stamen united with 

 the rest at least half its length; leaves dotted with yellow sessile oil-glands 

 on the under side, 6. Harpalyce. 



5. BRONGNIARTIA H.B.K. Nov. Gen. & Sp. 6: 453. 1824. 



Perallea H.B.K. Nov. Gen. & Sp. 6: 469. 1824. 

 Megastegia G. Don, Gen. Hist. 2: 468. 1832. 



Shrubs or trees, with odd-pinnate leaves; stipules present but often caducous. Leaflets 

 entire-margined, usually distinctly petioluled and sometimes with minute subulate or setaceous 

 stipels. Floweis normally axillary, solitary or in 2-7-flowered sessile umbels; in some species 

 the upper floral leaves are reduced to the two stipules and the flowers become falsely racemose. 

 Bractlets 2, close under the calyx, either foliaceous, resembling the stipules, persistent or 

 deciduous, or else minute or lepresented by small hair-tufts. Calyx partly 2-lipped; the upper 

 2 lobes united two-thirds to four-fifths their length, the lower 3 free to near their base or 

 occasionally united higher up, in one species above the middle. Corolla papilionaceous, 

 and red, brown, or purple; banner broad, orbicular or broadly obovate, short-clawed; wings 

 obliquely oblanceolate or obovate, more or less falcate, with a short fleshy claw and a rounded 

 auricle at the base of the blade on the upper side; keel-petals obliquely obovate or broadly 

 lunate, tapering to the fleshy base, their blades united above the middle to the tip. Upper- 

 most filament free, the rest united into a sheath; anthers oblong, all alike, or the alternating 

 ones shorter, the connective without appendage. Ovary short-stipitate; style fililorm, in- 

 curved, with a small sometimes capitate stigma; ovary several-ovuled. Pod flat, elongate, 

 often somewhat wing-margined on the upper suture. 



Type species, Brongniartia mollis H.B.K. 



Lower three calyx -lobes united to above the middle; flowers 3-7 together, 



at the end of the branches or in the upper axils. I. Bilabiata. 



Lower three calyx-lobes free to near the base or at least below the middle. 

 Flowers pseudo-racemose, the floral leaves all or the upper ones reduced 

 to the mere stipules, which resemble bracts; flowers 1-4 at each 

 node. 

 Leaflets 1-5, strongly reticulate; stipules very large. II. Inconstanies. 



Leaflets 7 or more; stipules smaller. III. Podalyrioides.
