THE MADDENI SERIES OF RHODODENDRON. 21 
perulae in about 4-5 series, few, broadly ovate-orbicular, the 
outer leathery, minutely downy, all provided with small rather 
scattered scales except towards the margins, the latter very 
minutely fringed with extremely short hairs; scars of the 
fallen perulae very crowded (contiguous), longitudinally linear ; 
pedicels stout, 1.3-1.5 cm. long, about 3.5 mm. thick, covered 
with small nearly contiguous scales, not hairy ; bracts not seen. 
Calyx 5-lobed, the lobes frequently very unequal, broadly ovate 
to oblong, normally about 4 mm. long but occasionally the 
adaxial one elongated to 1.5 cm. long, rather densely scaly 
except towards the margin, not ciliate except the elongated one, 
which bears a few short hairs at its tip. Corolla tubular funnel- 
shaped, fleshy, white with a faint flush of rose on the outside 
of the lobes which are outermost in bud; tube 4.5 cm. long, 
slightly widened in the upper part, covered with scales outside 
about their own diameter apart ; limb with a spread of 8-10 cm., 
nearly flat, 5-lobed, the lobes broadly suborbicular, about 4 cm. 
wide, with undulate margins, scaly outside except towards 
the margins. Stamens 20, about as long as the corolla tube; 
filaments glabrous ; anthers 5 mm. long, orange-yellow. Ovary 
to-celled, rather short for the size of the flower, covered with 
contiguous scales ; style exserted, a little longer than the total 
length of the corolla, scaly its full length except where it expands 
into the large 5-lobed disciform stigma. Capsule oblong-ellip- 
soid, 2-2.5 cm. long, about 1.4 cm. thick, ro-celled. Szeds 
3-4 mm. long, tailed-acuminate, scarcely winged.

This species was named -in compliment to Major Madden 
of the Bengal Civil Service, of whom Sir J. D. Hooker * says 
“‘a good and accomplished botanist, to whose learned memoirs 
on the plants of the temperate and tropical zones of north-west 
Himalaya the reader may be referred for an excellent account 
of those regions.”’
