1. Calliearpa Linn. #^M (Tzu Chu Shu) 

 Shrubs or trees with opposite simple usually serrate lvs. and small blue, purple 

 or white 4-merous fls. in axillary cymes; corolla regular, with a short tube; stamens 

 4, equal, not long exserted, with a small staminode; ovary 4-celled, 4-ovuled; stigma 

 small and simple: fr. a small berry-like drupe, longer than the calyx, with 2-4 stones. 

 About 40 species, mostly in tropical and subtropical eastern Asia, Malaya, Australia 

 and America; 16 in China. (Greek: hallos, beauty, and karpos, fruit.) 



Key to the Species 



a. Calyx tubular, deeply 4-cleft, the lobes each bearing in flower 

 a long slender tip or appendage: brts. stout, densely fulvous 



tomentose : If. blades 14-24 x 4-8 cm 1 . C. loureiri 



aa. Calyx campanulate or cyathiform, the rim very shortly toothed 

 or nearly truncate, 

 b. Peduncles of the infl. shorter than the petioles, or some- 

 times as long. 

 Brts. stellate pubescent, becoming more or less glabrous: 

 lvs. lanceolate (often narrowly so), acuminate, 10-20 x 

 2 .5-5 .0 cm. , short-petiolate, nearly glabrous at maturity ; 

 margins sharply serrate towards the tip, somewhat 

 wavy: peduncles of the infl. very short: calyx glabrous 



or nearly so in fruit 2 . C. brevipes 



Brts. scurfy-stellate-pubescent: lvs. broadly elliptic to 

 lanceolate-oblong, 5-15 cm. long, acuminate; cuneate 



at base ; margins serrate , 3. C. bodinieri 



bb. Peduncles of the infl. longer than the petioles. 



c. Leaf blades cuneate or rounded at base, not at all cordate. 

 Leaf blades cuneate: margins serrate. 



Leaf margins sharply dentate above the middle, but 

 not on the acuminate tip; blades 2-8x1.0-3.5 



cm.: anthers short-oblong, opening by slits 4. C. dichotoma 



Leaf margins irregularly serrate, except at base; 

 blades 5-12 x 1 .5-4 cm. : anthers narrowly oblong, 

 opening by terminal pores 5 . C. japonica
