252 ERICACEAE. (HEATH FAMILY.) 



$ 1. LEUCOTHOE PROPER. Anthers awnless; the cells sometimes obscurely 2- 

 pointed: stigma depressed-capitate, 5-rayed: racemes sessile (dense), produced at 

 the tin>? of flowering from scaly buds in the axils of the coriaceous and shining per- 

 sistent leaves of tJie preceding year, shorter than they : bracts persistent : bractlet* 

 at the base of the short pedicels. (Seed-coat loose and cellular, wing-like.) 



1. 1*. axillaris, Don. Leaves lanceolate-oblong or oval, abruptly pointed at 

 acute, somewhat spinulose-scrrulatc, on very short petioles; sepals broadly ovate. 

 (Andromeda axillaris, Lam.) Banks of streams, Virginia, in the low coun- 

 try, and southward. Feb. - April. Shrub 2 - 4 high. 



2. li. GatCSl>ei. Leaves ovate-lanceolate, taper-pointed, serrulate with cili- 

 ate-spinu!ose appressed teeth, conspicuously petioled (3' -6' long); sepals ovate- 

 oblong, often acute. (Andr. Catcsbsei, Walt. A. axillaris, Michx. A. spinu- 

 losa, Pursh. L. spinulosa, Don. ) Moist banks of streams, Virginia along the 

 mountains, and southward. May. Shrub 2 -4 high, with long spreading 

 or recurved branches. Flowers unpleasantly scented. 



$ 2. EtlBOTRYS, Nutt. Anthers awned: stigma simple: bractlets close to the 

 calyx, and, like the sepals, of a rigid texture, ovate or lanceolate, pointed: placentce 

 merely spreading : flowers very short-pedicelled, in long one-sided racemes, which 

 mostly terminate the branches, formed with them in the summer, but the flower-buds 

 not completing their growth and expanding till the following spring : bracts awl- 

 shaped, deciduous : leaves membranaceous and deciduous, serrulate, the midrib and 

 veins beneath pubescent. 



^. lt reci'irva. Branches and racemes recurved-spreading ; lea res lanceo- 

 late or ovate, taper-pointed ; sepals ovate; anther-cells 1 -awned ; pod 5-lobed; seed* 

 fiat and cellular-winged. (Andr. recurva, Buckley.) Dry hills, Aleghanies of 

 Virginia and southward. April. - - Lower and more straggling than t{ e next 



4. It. race III 6sa. Branches and racemes mostly erect; leaves oblong or 

 oval-lanceolate, acute ; sepals ovate-lanceolate ; anther-cells each 2-awned ; pod not 

 lobed ; seeds angled and wingless. (Andr. racemosa & A. paniculata, L.) Moist 

 thickets, Massachusetts to Virginia near the coast, and southward. May, June 

 Shrub 4 - 6 high. Corolla cylindrical. 



8. CASSANDRA, Don. LEATHER-LEAF. 



Calyx of 5 distinct rigid ovate and acute sepals, imbricated in the bud, ana

 apex, awnless. Pod depressed, 5-celled, many-seeded ; the pericarp of 2 layers, 

 the outer 5-valved, and later the cartilaginous inner layer 10-valved. Seeds 

 flattened, wingless. Low and much-branched shrubs, with nearly evergreen 

 and coriaceous leaves, which are scurfy, especially underneath. Flowers white, 

 in the axils of the upper small leaves, forming small 1-sided leafy racemes; the 

 flower-buds formed in the summer and expanding early the next spring. (Cos-
