CONSPECTUS TABULARUM. 9 
Descr.—A tall, slender, nearly glabrous shrub, with virgate branches. 
Leaves on short petioles, patent, ovate-oblong, 2-3 inches long, glabrous, 
but minutely granulated on the upper surface, repand, obtuse or sub- 
acuminate, veiny. acemes terminal, unilateral (eymoid), many flow- 
ered ; bracts opposite, minute, subulate ; pedicels 2-3 lines long, cer- 
nuous, bracteolate at a line from the base. Calyx continuous with the 
pedicel, equally 5-partite, with narrow-subulate segments. Corolla 
nearly two inches long, pale-lilac, of thin, membranous substance and 
veiny, tubular below, campanulate upwards, with a deeply 5-lobed, 
subequal, erect limb; the segments oblong, blunt. Stamens inserted at 
the top of the narrow part of the corolla, shorter than the limb; two 
perfect, with sagittate, equal-sided, 2-celled anthers; two filiform, 
nearly as long as the others, without anthers. Style filiform, with a 
minute, bifid stigma; ovary bilocular, with 2 ovules in each cell. Cap- 
sule unknown. 
Described by fr. Sanderson, its discoverer, as a beautiful shrub, 
‘fone mass of most delicate, pendant, pale-lilac, campanulate flowers.” 
Our figure, taken from a dried specimen, is perhaps too stiff, nor have 
we been able, probably, to restore the delicate corolla to its true form. 
I trust that this ornamental plant may before long be introduced to 
English gardens. The generic name is given in honour of my venerable 
friend, James Townsend Mackay, LL.D., author of Flora Mibernica, 
and for many years the able superintendent of the Dublin University 
Botanic Gardens. ‘‘ Mfackaya’’ Arn. is the same as Lrythropalum of 
Blume, as I am informed by Dr. Hooker.

quite simple. eaves 2-3 inches long, 2 lines broad, lanceolate-linear,
