24 RECORDS OF OBSERVATIONS ON SIR WILLIAM MACGREGOR’S 
flowers three or few, terminal, on very short pedicels ; calyx reduced to a very narrow 
membrane ; tube of the corolla cylindric, about three times as long as the lobes, 
oradually somewhat widened upwards, outside scantily lepidote, inside towards the 
base beset with scattered very short hairlets; stamens ten, nearly as long as the 
corolla; filaments on their lower portion bearing scattered hairlets ; anthers hardly 
more than twice longer than their breadth ; style less than half as long as the corolla; 
stigma-cover slightly dilated; disk annular, almost glabrous; ovularly five-farrowed, 
as well as the greater portion of the style bearing a velvet-like indument. 
Mount Knutsford. 
Leaves one to one and a half inches long, but only few on our only specimen. 
Length of corolla about one inch. Anthers barely one-tenth of an inch long. Style 
of expanding flower hardly half an inch long. Ovularly also proportionately short. 
Stands in close relationship to R. verticillatum; but that plant seems smoother, has 
the flowers with much ampler corolla, the anthers rather longer, the style nearly 
olabrous and the ovulary bearing a squamular indument. 
Through future more extensive material the characteristics, here given, may 
become enlarged. A new monography of Ericacee, inclusive of Vacciniacex, is more 
now wanted than almost any other descriptive treatises on orders of plants, as the 
vastly accumulated collections, obtained from various parts of the globe, also within 
this large ordinal complex, needs critically connected investigations. The collection 
contains also a fragmentary specimen of an allied and possibly conspecific plant; of 
this the leaves are distinctly stalked, ovate, slightly pointed and smoother; the corolla- 
tube is much more slender, though the lobes are broadish; the filaments are nearly 
or quite glabrous, and the pistil bears a very close stellular indument. It might 
receive as a variety or species the name R. leptanthum. 
Rhododendron culminicolum: 
Branchlets almost glabrous ; leaves small, on short stalks, mostly whorled, from 
elliptic-ovate to broad-lanceolar, nearly flat, quickly glabrous, beneath dotted, their 
venules faint ; flowers comparatively small, terminally few together ; stalklets quite 
slender, about thrice shorter than the flowers; calyx reduced to an almost circular 
membrane, but often also extended into one or two acute lobes; corolla almost 
glabrous outside, its tubes cylindric nearly throughout, about thrice as long 
as the lobes, inside towards the base bearing simple short hairlets; stamens ten, 
almost as long as the corolla; filaments beset with spreading hairlets at their lower 
portion ; anthers only about doubly as long as broad; style nearly as long as the 
stamens, upwards glabrous ; stigma-cover slightly dilated; disk broadish, annular, 
faintly ciliolated ; ovulary cylindric-conical, bearing a velvet-like vestiture,
