244 ricker: synopsis of albizzia 



oblong-elliptic, 2-3 cm. long, 1-2 cm. broad, the midvein but 

 slightly excentric; flowers 1 cm. long, many in heads on axillary 

 peduncles 4-9 cm. long, the pedicels 5-6 mm. long, glabrous; 

 calyx 4-4.5 mm. long, glabrous, with shallow teeth; corolla 

 white, puberulent only at the tips of the lobes; pods nearly 

 sessile, 13-14 cm. long, 22-28 mm. wide, coriaceous, abruptly 

 obtuse at both ends, mucronate-pointed; seeds smooth, brown, 

 elliptic, thin, 8-9 mm. long, 4.5-5.5 mm. wide. 



China: Yunnan; j\Ieng-tsze, A. Henry 10683, in flower May 

 29, in fruit June 30, 1896. (Type in U. S. Nat. Herb.). 



CC. Flowers puberulent throughout. 

 Albizzia lebbeck (L.) Benth. Lond. Journ. Bot. 3: 87. 1844. 



Mimosa lehbek L. Sp. PL 516. 1753. 



I have not seen Henry's specimen from Ichang reported by 

 Forbes and Hemsley, but think it probable that it is A. kalkora, 

 as are most of the specimens from China that have b'een named 

 as above. It is doubtful if the true A. lehbek is found wild in 

 China except rarely as an escape from cultivation around some 

 of the larger cities. The only apparently genuine specimen I 

 have seen from China was from Hong-kong. A. viacrophylla 

 Bunge, usually referred here as a synonym, is quite distinct and 

 is a synonym of A. kalkora. 



AA. Flowers in heads, long pedicelled; heads in subcorymbose 

 racemes; leaflets less than 2.5 cm. long. 

 Albizzia retusa Benth. Lond. Journ. Bot. 3: 90. 1844. 



This species is distinguished from its nearest relative, A. 

 pedicellata Baker, by having its leaflets only 6-10-pinnate instead 

 of 15-20-pinnate as in that species. 



Formosa: South Cape, Henry 992. It is also found in the 

 Philippines. 



AAA. Flowers axillary, sessile or very shortly pedicelled, 

 small; corolla 4 or rarely 6 mm. long; peduncles short, 

 fascicled, often in numerous short leafless panicles. 

 B. Flowers glabrous.

Mimosa corniculata Lour. Fl. Cochinch. 651. 1790.
