4. AZALEA, Linn. 



Characters of RJiododendron, except that the stamens are usually 5 only 

 aiul the leaves deciduous. Two of the following species, however, and one or 

 two other east Asiatic ones, have usually 8 or 10 stamens, and are therefore 

 placed by some botanists in Rhododendron, but, on account of the deciduous 

 leaves and habit, they are more generally retained in Azalea. 



The genus as generally limited is chiefly N. American, with a few species "from temperate 

 or subtropical Asia. 



Stamens 5. Calyx glabrous. Corolla nearly rotate I. A. ovata. 



Stamens 8 to 10. Calyx hairy. Corolla campanulate. 



Leaves oval-oblong, hairy. Flowers about 3 from each bud . . . 2. A. indica. 



Leaves ovate, glabrous when full-grown. Flowers 1 from each bud . 3. A. squamata. 



1. A. ovata, Llndl. in Journ. Hart. Soc. i. 149, and ii. t. 2; Hook. Bot. 

 Mag. t. 5064. A much-branched glabrous shrub. Leaves few, at the ends 

 of the branches, ovate or oval-oblong, seldom above an inch long, the 

 veins scarcely cons])icuous. Flowers issuing singly from scaly buds of which 

 several are usually clustered at the ends of the branches. Pedicels short, 

 slightly glandular, hispid. Calyx-lobes glabrous, ovate, obtuse, thin, about 

 3 lines long. Corolla nearly rotate, about 1| in. across in the wild specimens, 

 white, w^th purple specks, cleft to near the base into 5 oblong lobes, the upper- 

 most the broadest. Stamens 5, with haiiy filaments. Capsule ovate, 5 -celled, 

 about 3 Hues long. — A. myrtifoUa, Champ, in Bot. Mag. under n. 4609. 



On rocks of the Black Mountain, Champion. Also in Chusau, but not known from else- 

 where. 



2. A. indica, Linn.; Bot. Mag. t. 1480 «w^ 2667 ; Bot. Reg. t. 811, 

 1700, and 1716. A much-branched shrub, the young branches and leaves 

 more or less covered with stiif appressed rusty or almost silky hairs. Leaves 

 oblong or oval-oblong, acute, seldom above \\ in. long, and often under 1 in. 

 in the w^ild specimens, narrowed into a very short petiole, often becoming 

 glabrous above, but always retaining the hairs underneath. Flowers almost 

 sessile, usually 3 together from the same scaly bud ; the inner scales very 

 hairy. Calyx also hairy ; the lobes lanceolate or oblong, 2 or 3 lines long. 

 Corolla wdth a short tube, obliquely and broadly campanulate, full 2 in. across, 

 divided to about the middle into 5 broad rather unequal lobes. Stamens 

 usually 9 or 10, of which 1 much shorter than the others. Capsule ovate, 

 acuminate, very haii*y, 4 or 5 lines long. — Rhododendron indlcum, Sw. ; DC.
