Naung-Chaung, Nwai divide. In marshy leaf mould by streams
in elfin forest shade. Alt. 10,000 ft. June 1914.”’ F. Kingdon
Ward. No. 1708.

A peculiar species ; the racemes have a very zigzag rhachis
with linear reflexed bracts, and very slender pedicels, which
appear to be more or less prehensile. The upper and lower
petals have an apiculus ; the bud at a certain stage consequently
appears as if two-horned. The specific name is intended to in-
dicate the delicately poised flowers which must be set in motion
by the lightest current of air.

C. hebephylla, Diels appears to be a very variable plant. It
is quite possible that more than one species is included in this
aggregate, and I have not been able to correlate to my satis-
faction the fruiting specimens with the flowering. At the same
time a detailed examination of the structure of the leaf and
indumentum, as well as of the flowers, shows the examples to
be very closely connected. Until further material is available
I have judged it better to keep them under one specific name.
Authentic fruiting specimens of the type are much wanted.
The series shows a very definite approach to C. racemifiora,
K. Koch, var. soongorica, Schneider, common in Western
Szechwan, but the material at my disposal is not sufficient for
me to determine whether C. hebephylla should be ranged along
with or under that species.

possibly a variety of J. dipyrena. The present variety is scarcely
equivalent to the Manipur plant, and is nearer it than to any

Edin. , Viil (1913), 109. ((0

This species is more closely allied to she saccata, Rehder than
to L. trichopoda, Franch. as previously suggested. The flower
of L. chlamydata is larger and fleshier than that of L. saccata,
with a much broader tube, which is very densely hairy inside,
while the style is setose rather than villous: The corolla is a
deep golden yellow.

Two Yunnan sheets collected by F. Kingdon Ward appear
to approach L. saccata, Rehder very closely. Ward No.
602, from boulder screes at 13,000 ft. in the Atuntsu district
of N.W. Yunnan, almost matches the Szechwan plants—the

corolla is, however, about 13 mm.long. Ward No. 637, a shrub
of 6-8 ft., in open places on screes at 14,000 ft., from the same
area, is very similar, except for the glabrous style—perhaps
that will prove to be at most only a varietal distinction.
The affinity of these last is more with L. saccata than with
L. chlamydata.

The flowers of this species have not hitherto been described :—

‘“‘ China :—Tree of 25-40 ft. In fruit. In thickets on the
western flank of the Shweli-Salween divide, Yunnan. Lat.
25° 20’ N. Alt. gooo ft. Aug. 1912.” G. Forrest. No. go4o.

This is a very remarkable species. At maturity it is con-
spicuous by the large size of the leaflets which often exceed
8 inches in length, by the small number of the pairs of leaflets
and by their stout coriaceous texture. In the young plants
observed in cultivation in the Royal Botanic Garden the leaves
are generally trifoliate, with a shining upper surface and distinct
serration ; in plants of a foot high trifoliate leaves are found
along with leaves showing 2-4 pairs of leaflets. Among the
Chinese species of Pyrus of the section Sorbus the species most
akin appears to be S. Sargentiana, Koehne; the leaflets, how-
ever, in that species are decidedly small, have a long acuminate
apex, a much thinner texture, and a more or less deciduous
covering of wool especially on the under surface. Another
close ally is P. insignis, Hook. f. from the East Himalaya, which
has smaller more numerous leaflets and is much less glabrous.
The specific name is in honour of Mr. Robert Lewis Harrow,
Head Gardener of the Royal Botanic Garden since 1902.

The generic name is in honour of the wife of the collector.
The exact position of this genus in the Rubiaceae is not satis-
factorily determined. Mature fruit would aid materially. The
plant in its floral structure is closely allied to the Alberteae, a
tribe confined to Africa; from them, however, it is widely
different in habit. In this latter respect it suggests Hamiltonta
among the Paederieae.

A distinct species of the Taliense series and near to RA.
taliense, Franch. itself. The white compact shining indumentum
on the under side of the more elliptic and larger leaves enables
one to differentiate the plants at sight, and then the nearly
glabrous petioles and the glabrous pedicels confirm the diagnosis.
In aspect the foliage recalls in miniature that of Rh. Clementinae,
G. Forrest, but that is a plant which has 7 lobes to the corolla
and stamens about 16, not as in the Taliense series 5 corolla-lobes
and Io stamens.

This is a new species of that delightful series of rhododen-
drons which centres in Rh. haematodes, Franch., and it has the

_characteristic attractive features of the series in the firm foliage
with pale under-surface indumentum, the thick tubular cam-
panulate 5-lobed corolla of a rich orange-red tint and the deep
purple anthers. From Rh. sanguineum its membranous calyx
and pubescent staminal filaments separate it. From Rah.
dichroanthum, Diels the rounded not tapered base of the leaf,
the different indumentum of the ovary, and the uateee capsule
are distinctive marks. The plant is in cultivation

N.E. Yunnan. Dry hills behind Mo-tsou. Alt. 850 m. (ste ?).
Shrubby rhododendron with persistent leaves and small rose
flowers. Maire. No. 137 in Herb. Edin.

A species akin to Rh. siderophyllum, Franch. which to our
present knowledge does not spread out of East Yunnan. Rh.
bivelatum has smaller leaves, which are not so thick as
those of Rh. siderophylium, and can be recognised at once by
the somewhat unusual character in its type of leaf of a coating
of hairs on the under-leaf surface intermixed with the peltate
scales. The petiole shares the puberulous as well as lepidote
character. Like Rh. siderophyllum our species retains the
bracts during flowering and they completely envelop the
pedicels, but the bracteoles in RA. bivelatum are much shorter,
only about half the length of the pedicels, whilst in Rh. sidero-
phylium they are longer than the pedicels.

I only know the plant in the single sheet of specimens which
came to us from Abbé Maire, and there is not another plant in
his collection for which it can be mistaken. Whilst the details
of character especially of the flower take it to Rh. siderophyllum,
yet it is not as like that species as is another West Yunnan
species—Rh. stereophyllum, Balf. f. et W. W. Sm. (see p. 159).
The three species can be recognised at sight thus :—

Rh. siderophyllum _. Twigs stout red densely lepidote and
becoming closely warted; leaves
large pointed.

Rh. stereophyllum _ . Twigs stout red distantly lepidote and
puberulous with short hairs and
becoming distantly warted; leaves
medium rounded. |

Rh. bivelatum . Twigs thin scurfily lepidote and puber-
ulous with long hairs, not becom-
ing warted ; leaves smaller pointed
obtuse.

Bhutan. Punakka. Alt. 6000-7000 ft. 8 ft. bush on
steep dry hillside with pink and scented flower. R. E. Cooper.
No. 3936. 27th May roI5.

Whether this plant may be the same as one of the forms of
kh. Jenkinsii, Nutt. allied to Rh. Maddeni, Hook. f. named by
Nuttall * from Bhutan I will not discuss. It is possible that
one or more of these forms found by Booth may be distinct
species, but the descriptions are altogether insufficient to enable
one to say what Booth’s plants really were. Foliage alone in
this series of rhododendrons is an unsafe guide to species unless
leaf structure is examined microscopically—and neither the
corolla nor stamens—critical characters in the series—of Rh.
Jenkinsii and the forms included under it were known to Nuttall.
Cooper’s plant here described is a distinct one in the Maddeni
series. The most easily seen diagnostic mark is the small
corolla with short tube a little over a centimeter long. From
Rh. Maddeni and from Rh. calophylium, Nutt. it is dis-
tinguished also by the larger calyx and by the puberulous not
glabrous stamens, and then the leaves are obtuse and relatively
to length much wider. Like Rh. manipurense, Balf. f. et Watt
in its stamens it has a smaller calyx and corolla and the foliage
also is much smaller. :

Mr. Cooper collected his plant in May and obtained no fruit,
so that this species is one that remains to be introduced to
cultivation by some future explorer.

between them. Rh. Souliei is now a familiar plant of cultiva-
tion, thriving at Edinburgh in any situation, and Rh.callimorphum
introduced by Mr. J. C. Williams, has flowered (May 1917) aud
appears to be as desirable a species as Rh. Souliei. By the
character of foliage the two plants are easily diagnosed. RA.
callimorphum has abundance of red glands appearing as minute
dark points distributed over the under surface of the leaf and
the petiole is clad with sessile globular glands. Rh. Souliei has
no glands on the leaf under side and the petiole bears more or
fewer stalked red glands which often extend to the margin of

the lamina at the base. Franchet* has it: ‘‘ petiolo crasso
I5 mm. longo, subtus glandulis consperso caeterum glabro,”
but I do not find such restriction of glandular surface in our
cultivated plants. These glands tend to disappear as the leaf
oldens but their traces remain visible. In the text accompany-
ing the figure of Rh. Souliei in the Botanical Magazine (1915),
t. 8622, there is an obvious misprint—the Latin diagnosis and
description gives the lamina as eglandular whilst the English
description says glandular. It is true that on the upper surface
of the lamina as it opens from the bud there is a sprinkling of
stalked red glands, but they have disappeared from the fully
expanded lamina, which is eglandular both above and below.
In the calyx characters there is much difference from Rh. Souliet,
for we miss in Rh. callimorphum the large membranous gland-
margined lobes of Rh. Souliei and find only small unequal
glandular projections as is the case in Rh. Williamsianum, Then
the style in Rh. callimorphum has long-stalked glands at the
very base only and is not glandular throughout as in Rh. Soulter.

scribed * briefly two species—Rh. sparsiflorum and Rh. lucidum
—upon imperfect material collected by Booth in Bhutan which
he regarded as nearly allied to Rh. camelliaeflorum. Rh. sparst-
florwm is treated as a synonym of Rh. camelliaeflorum by C. B.
Clarke,j who mentions (p. 475) Rh. lucidum as an imperfect y
known species. There is the possibility that Cooper’s plant
may be one or other of Nuttall’s species, but there is no certainty,
for Nuttall’s descriptions were taken from specimens not in
flower and the flower character is a dominant one in Rh. Cooperi.

The rhododendron phylum which is represented on the
Mekong-Salween Divide by Rh. Wardii, W. W. Sm. finds ex-
pression to the East on the Mekong- Yangtze divide, the Chungtien
plateau, and in the N.E. of the Yangtze bend in the plant here
described as Rh. croceum, which diverges so much—in some
characters clearly in relation to the drier environment—that on
the evidence it must be kept distinct from the western type.
Mr. Forrest has specimens from several localities, and they all
agree in the characters which differentiate Rh. croceum from
Rh. Wardii, near one another though these plants are. We
want more of the Mekong-Salween plant for completion of the
differential diagnosis, but the following characters suffice for
recognition of the two species :—

Rh. Wardii has adult leaves typically nearly elliptic with
rounded summit in middle of which lies the horny mucro ;
croceum has always oblong leaves which slightly taper at the
apex into the mucro and are not usually rounded. ;

The inflorescence in Rh. Wardii is quite umbellate; in Rh.
croceum racemosely umbellate with a rhachis of about 1.5 cm.

ng.

ox

.

The caudate outer bracts of Rh. crocewm are not visible on
any of the buds of Rh. Wardit. 5

Both the calyx lobes and the outside of the corolla in Rh.
croceum are gland-dotted; in Rh. Ward the calyx is more
sparingly glandular and the corolla is eglandular. —

The ovary in Rh. Wardii has many almost sessile red glands
covering it; in Rh. croceum the glands which form an even
denser covering to the ovary have long stalks and they are
turned upwards to the top of the ovary. ;

The capsule in Rh. Wardii is shorter and thicker and is
sprinkled with short glands ; in Rh. croceum the longer thinner
Capsule is densely covered with long-stalked glands.

Rh. croceum belongs to a type of rhododendron which is
presented in several species throughout Western China and the
adjoining countries and which also appears in the Himalaya.

The general features of the series may be briefly stated thus :—

If this be a natural phylum its name should be Campy-
locarpum after the longest known species. I say if, because
whilst the species have a marked resemblance and have more
or less developed the technical character of a glandular style,
the longer thin curved capsule of Rh. campylocarpum is very
different from the short more nearly straight capsule of Rh.
Wardit and Rh. Williamsianum, and those are the only fruits I

BaLFour—NEw SPECIES OF RHODODENDRON. 07

know in the series. I do not however know at what value to
appraise fruit and seed character in rhododendron, for I have
seen too few of them in fruit.

I may note here that there is another series of rhododendrons
with somewhat similar distribution to which may be given the
name of Selense, presenting general features very like those of
the Campylocarpum series but distinguished at once by a
glabrous style on top of the glandular ovary. The species
belonging to it are :—

W. W. Sm. (1917). Yangtze divide and Chung-
tien plateau, II,000-12,000

ft. (Forrest.)

(Soulié.)

Rh. Stewartianum, Diels (1912). | W.N.W. Yunnan : Mekong-
Salween divide, 10,000—
11,000 ft. (Forrest.)

In the Selense series there appears the same contrast in
fruits as in the Souliei series. Rh. rhaibocarpum has a capsule
in all characters like that of Rh. campylocarpum and it con-
trasts with the short, nearly straight capsule of Rh. Souliet. —

It is convenient for the time to segregate these species in
the series I have named and thus to link together some of the
now numerous species of rhododendron. But I think that
hereafter it may be found that natural relationships call for a
Tegrouping of the species, and that they all belong to and may
be arranged by their affinities within a series for which we may

take the name Thomsoni, after the well-known Himalayan Rh.
Thomsoni. At present I take the Thomsoni series as a separate
one distributed in the Himalaya and Western China, and dis-
tinguished by the tubular campanulate corolla and the usually —
glabrous ovary and glabrous style, whilst in foliage and other
characters its species closely resemble some of those of the
Campylocarpum series and approach the Selense series. The
Thomsoni series I speak of includes :—

Rh. candelabrum, Hook. f. Sikkim, 10,000-11,000 ft.
(1849). (Hooker f.)

Rh. cyanocarpum, Franch. Mid. W. Yunnan: Tali,
(1895). 10-12,000 ft. (Delavay.)
Rh. eriphyllum, Balf. f. et | Mid. W. Yunnan, 11,000 ft.

W. Sm. (1917). (Forrest.)
Rh. Hookeri, Nutt. (1853). Bhutan, 8000-goo00 ft.
(Booth.)
Rh. rotundifolium, David W. Szechwan: Muping,
(1872). 12,500 ft. (David.)
Rh. Thomsoni, Hook. f. (1849). Sikkim,

II,000-13,000 ft.
_ (Hooker f.)

In support of the suggestion that all the species here named
belong to one phylum and that their separation in the three
series of Campylocarpum, Selense, Thomsoni is more artificial
than natural, I would point out that the gland coating of the
gynaeceum—the chief technical diagnostic mark of the series—
shows some variation. Rh. callimorphum and Rh. dasycladum
of the Campylocarpum series have the glands confined to the
base of the style and not covering the whole—a step as it were
towards the glabrous style of the Selense series. And then
Rh. candelabrum and Rh. eriphyllum are microforms respectively
of Rh. Thomsoni and Rh. cyanocarpum and in them the ovary
has some glands and shows thus a step towards the completely
glandular ovary in the Selense and Campylocarpum series. It
is of special interest to note that this variation occurs in both
the Himalayan and the Yunnan representative species.

This fine nants is s of special interest, cas whilst resembling
in many characters the rhododendrons of the series that centre
around Rh. selense, Franch., it differs from them in its character
of glandular style, which takes it nearer those of the Souliei
series, from which series it is excluded by the shape of its corolla.
Its nearest ally is certainly Rh. rhaibocarpum, Balf. f. et W. W.
Sm. They are members of a complex of which Mr. Forrest has
collected other members, but not in complete enough state to
supply material for estimation of their relationship and title to
specific rank. The special attention he will give to that group
during his present exploration of Yunnan will furnish data, I
hope, which will show us more than one new species in this
beautiful set of rhododendrons.

A species with flowers about a third larger than those of Rh.
discolor, Franch., to which it is nearly allied. The two species
are quite distinct. Rh. discolor has narrower and longer leaves
which are pointed at the tip and the whiter under surface wants
the red glands which punctulate the leaf in Rh. diaprepes. The
pale colouration of the leaf under-surface in both species is
due to the dome-shaped epidermal papillae coated with wax,
Then Rh. discolor has a really racemose inflorescence the rhachis
of which is as much as 4 cm. in length whilst in Rh. diaprepes
the flowers are distant on a rhachis only 1.5 cm. long. Franchet
describes the pedicels in Rh. discolor as quite glabrous—were
that constant it would readily differentiate the species from Rh.
diaprepes where they are always glandular. But Rehder and
Wilson say that the pedicels are “ occasionally sparsely
glandular ”’ in Rh. discolor, and Wilson’s specimens—Nos. 586
and 1077—bear out their statement. In both of these the pedicels
are glandular. In addition to the size of flower the very
pubescent stamens of Rh. diaprepes separate it from Rh. discolor,
where they are glabrous. From Rh. rasile, Balt. f. et W. W. Sm,
the absence of glands from the outside of the corolla readily
distinguishes Rh. diaprepes.

This is a fine species and should be an ornamental plant in
gardens. It has been raised from seeds collected by Mr. Forrest
under No. 5881 for Bees Ltd. but has not yet flowered in
cultivation.

It has all the aspect of plants of the Selense and Souliei
series. Its style, glandular throughout, denies it a place in the
Selense series. Of the members of the Souliei series the species
nearest to it are Rh. callimorphum, Balf. f. et W. W. Sm.,
Rh. puralbum, Balf. f. et Ward, and Rh. Souliet, Franch., but
they are easily distinguished. It recalls by its foliage AA.
puralbum, Bali. f. et Ward, but that species has a pure white
corolla, large membranous calyx glandular at margin only, and
puberulous staminal filaments. Rh. callimorphum, Balf. f. et

. W. Sm. has cordulate leaves and puberulous staminal
filaments. Rh. Souliei, Franch. has also cordulate leaves and
the calyx is large and membranous.

The 7-lobed corolla and 14 stamens suggest the Fortunei
series as its affinity, but the leaf form is hardly that of the series
and the character of the under-leaf surface is entirely that of
Rh. Souliei.

species of the series. The conspicuous style-character is shared
by Rh. pogonostylum, Balf. f. et W. W. Sm. alone in the series,
nd in that species perhaps Rh. facetwm finds its nearest ally.
The corolla hairy on the outside in Rh. pogonostylum and the
glands beneath the tomentum on the ovary separate it readily.

. facetum carries farther westwards into Burma the dis-
tribution of a Irroratum series. Kh. tanastylum, Balf. f. et
Ward found at Hpimaw is the only species outside Yunnan
hitherto assigned to the series, which occupies a much wider
geographical area than I knew of when I read an account of
the series before the Botanical Society of Edinburgh in 1917.
I have since that date found amongst collections made by Mr.
R. E. Cooper in Bhutan specimens under Nos. 4086, 4160,
4978 of Rh. Kendrickii, Nutt. corresponding in all respects with
Mr. Griffith’s Bhutan specimens of the species under No. 2235.
Analysis of the new Bhutan material of this little-known species
suggests that Rh. Kendrickit is an Eastern Himalayan repre-
sentative of the West Chinese forms assembled in the series
Irroratum. Nuttall,* and following him C. B. Clarke,f thought
the affinity of Rh. Kendrickit was with Rh. arboreum, Sm., from
which it differed, as Clarke says, “‘ by the very narrow capsule.”

association of the two species. My overlooking Cooper’s
specimens when dealing with the Irroratums of W. China was
a consequence of my placing them at a first sorting amongst
forms of Rh. arboreum. But Rh. arboreum’and Rh. Kendrichii
assuredly belong to different phyla. The whole indumentum
and other characters of the Arboreum series typified in Rh.
arboreum are different from those of Rh. Kendrickii, which con-
form with those of Rh. ivroratum, Franch. and its allies.

Rh. Kendrickii is not common in cultivation. We have no
plant at Edinburgh notwithstanding endeavours to obtain it.
Nuttall’s description * is very slight, and that in the Botanical
Magazine is derived from a cultivated plant. I therefore give |

pany with it and that seeds of the two collected together have
been mixed. We have no record in Mr. Forrest’s dried collec-
tions of a plant like Rh. Fittranum.

Rh. Fittianum promises to be a valuable horticultural plant,
and is also of interest from the botanical standpoint.

It belongs to the Dauricum series of rhododendrons which
is typified in Rh. dauricum, Linn., a familiar and decorative
plant of our shrubberies which has been in cultivation since
1780. Rh. dauricum is a plant of considerable range in N.W.
Asia. Its distribution, as given by Maximowicz in 1870,* is :—
Siberian Altai to the extreme east, Kamtschatka, Davuria,
Russian Manchuria to the mouth of the Amur, and the con-
fines of Corea. Hemsley ¢ records a remarkable extension of its
range into Chili and Shantung. It is now known from Yezo in
the extreme north of Japan. From West China there is no record.

The most striking feature of Rh. Fittianum is its floriferous-
ness. This is due to the development of flower-shoots in the
axils of the leaves throughout the length of the shoots. This
free flower-formation is not common in rhododendrons. The
most familiar example is perhaps that of Rh. racemosum, Franch.,
a plant commonly cultivated in gardens nowadays. «The West
Himalayan Rh. virgatum, Hook. f. and its Chinese representative
Rh. oleifolium, Franch. show it also. But the branching in
_ Rh. Fittianum is not quite the same as in these species., In them
each axillary flower-shoot is that and no more—it begins with
sterile bracteal scale-leaves covering the flower-bud and ends
in the inflorescence. In Rh. Fittianum the axillary shoots
are vegetative in the first instance, produce a few green leaves
and then end in the flower-bud covered by its bracts. In
Rh. dauricum the lateral flowering shoots are axillary to the
last-formed leaves only, and are therefore clustered at the
end of the mother shoot and they may or may not begin with
foliage-leaves.

shoots are always fulvous tomentose not glabrous. Its under-
leaf indumentum does not appear to be deciduous, and the

_ structure of the indumental hairs is very different. Here they

are relatively large dense flocks, each with a somewhat long
stipe of many cells branching off at the top into many long
twisted threads which do not in dried specimens seem to inter-
lace to form a surface wool-like layer but stand out like strands
of a mop, giving a sort of powdery aspect to the whole surface
of theindumentum. The hair-branches are of medium diameter,
neither filiform nor broadly vesicular. In Rh. Beestanum
the indumentum-hairs are true flocks also, but of rosette-type.
The basal stipe is very short and only some 5 or 6 short broad
vesicular hair-branches radiate from it, spreading out more or
less flatly, their walls often beautifully striate. These branches
are so interlaced as to give rise to a smooth suéde general sur-
face, which is most characteristic. Then the flocks are de-
ciduous. Other distinctive characters from Rh. Beestanum
are :—the leaves are not rugulose on the upper surface, the
petioles not glabrous but coated with indumentum, the inflor-
escence umbellate not racemosely umbellate, the shorter more
delicate pedicels, the smaller flowers, the narrower glabrous
ovary and the less expanded stigma.

The list does not include all the forms of the series. Both
from Western and Eastern Yunnan there are specimens which
do not come within the limits of described species. Their
position remains for future investigation to determine. Kh.
rubiginosum seems to be variable, and probably its specific
boundary will have to be redrawn when we get to know more
of the plants of which there is at present available for study
inadequate material. In the list given above I have cited for
its distribution only areas from which the type or undoubtedly
typical specimens have been brought.

Rh. fumidum belongs to the set within the Heliolepis series,
in which the uniform scales on the under-leaf surface are dis-
contiguous but separated by intervals less than the diameter
of the scales. Its nearest ally seems to be Rh. pholidotum, in
which the pedicels are longer, the calyx puberulous outside, and
the ovary hair-crested. The glabrous style of Rh. fumidum is
a character which it shares in the series with Rh. rubiginosum.
Rh. pholidotum is exceptional in having the style sometimes
glabrous sometimes pilose.

F, Kingdon Ward. No. 1793- 16.7.14.

This is a pretty species allied to Rh. sanguineum, Franch.
This series of rhododendrons is characterised by the white or
grey under-leaf indumentum forming a crusty uniform stratum
composed of floccose hairs with very short stalks from which
radiate long empty vesicular branches which by interweaving
form the smooth often crust-like surfate ; by the tubular cam-
panulate 5-lobed corolla; by the 10 stamens; by the ovary
densely coated with ascending chestnut-coloured fasciate hairs
often mixed more or less with greasy setae with club-shaped
ends; by the glabrous style and narrowstigma. The series seems
to be well developed along the Burma-Yunnan frontier from
Tibet southwards. Rh. herpesticum is readily separated from
Rh, sanguineum by the setulose twigs and petioles on which
there is also a lower indumental stratum of white floccose hairs.
Also the calyx-lobes are well developed. The indumentum-
characters also separate it from Rh. dichroanthum, Diels and
from Rh. apodectum, Balf. f. et W. W. Sm

otherwise exhibits. One notes that the upper surface of
the young leaves produces but few peltate scales and these
chiefly near the base of the lamina where it is about to join the
petiole and, as if by way of substitute protection the whole
surface becomes shortly puberulous. One may say that there
is over the whole plant a tendency to a development of hairs
alongside of and taking the place in part of peltate scales—on
the pedicels along with the scales, supplanting the scales on
the bracteoles, profusely covering the calyx-lobes associated
with but a few scales. Then the style and stamens are both
slightly longer than the corolla, and the style is longer than the
longest stamens—only slightly so but clearly.

Rh. invictum has its nearest ally perhaps in Rh. pholidotum,
but the pointed leaves, umbels with more flowers, closer-set
scales of that species are superficial diagnostic characters to
take along with the special features already mentioned
which are shown by Rh. invictum. In Rh. invictum, as in Rh.
pholidotum, the slight zygomorphy of the flower is marked. I
am not sure but that the character really marks all the species
in the series, but I have insufficient material and observation
for a precise statement.

This is one of these interesting forms which Mr. Kingdon
Ward has brought from East Upper Burma, carrying the types
of East Himalayan rhododendrons farther eastward. The
affinity of Rh. mallotum, Balf. f. et Ward is with the Sikkim
and Bhutan Rh. lanatum, Hook. f. Ward’s plant may be
spoken of as a crimson-flowered Rh. lanatum. The two species
are alike in their very thick persistent indumentum, the hairs
of which in Rh. lanatum are rather tree-like (dendriform) than
besom-like (scopiform) as they are in Rh. mallotum, and the
hair-branches of Rh. lanatum are also slenderer, curl more, and
interlock, are not stiff erect and patent. In addition to its
yellow corolla, the densely villous staminal filaments give a
character separating Rh. lanatum.

22nd July 1882.

In Sir George Watt’s Herbarium I found some sheets of this
thododendron about the precise identity of which he Was un-
certain, but which, as his field tickets show, appeared to him to be
more or Jess related to Rh. Maddent, Hook. f. yet different. These
Manipur plants-are all of them related to Rh. Maddent, Hook. f.
and its immediate microforms Rh. calophyllum, Nutt. and Rh.
Jenkinsii, Nutt., but they have diverged from the typical Rh.
Maddeni, Hook. f. by enlargement of the calyx and by develop-
ment of hairs on the filaments of the stamens. These two
Characters the Manipur plants possess in common with the
West Chinese, Rh. crassum, Franch. and its immediate allies
Rh. excellens, Hemsl. et Wils. and Rh. megacalyx, Balf. f. et Ward.

As regards the calyx-enlargement, it is to be noted that in
the dried specimens there is a slight irregularity in the calyx
lobes of Rh. manipurense. All of them are enlarged, but two
are commonly smaller than the others. Sir Joseph Hooker
points out that in the small calyx of Rh, Maddem the lobes are
unequal and the “upper lobe is often elongated. This is,
however, a very different condition from what appears in Rh.
mantpurense—although indicative of calycine enlargement as a
feature in the phylum.

I22 BALFOUR—NEW SPECIES OF RHODODENDRON.

I must point out also that in Rh. manipurense the androecium
has in numerical symmetry and length of stamens and anthers
the character of Rh. Maddeni. Hooker gives the number of
stamens in Rh. Maddeni as 17-20, and they are as long as the
tube. I find the same number and length in Rh. manipurense.
In this Rh. manipurense approaches Rh. Maddeni more nearly
than it does Rh. crassum and its allied forms named above, which
all have 10-12 stamens.

I wrote to Sir George Watt about his Manipur rhododen-
drons, and he has been so good as to send to me the manu-
script of his descriptions of all the species he met with during
his journeying in Manipur. The manuscript came to Europe
with his specimens in the eighties of last century but was not
published. I give here a transcription of what Sir George
Watt says about these forms which with reluctance he placed
under Rh. Maddeni :—

‘“‘ This is perhaps the most abundant bush on Japvo, Ching
Sow, and other hills above 7500 feet in altitude.

“On the young shoots its elliptical lanceolate leaves are
very much larger and broader than on the flowering branches,
bright shining green above and green with brown scales, becoming
almost ferruginous, below. Under the microscope these spots
are seen to be round peltate scales depressed like minute cups ;
in the bottom of each is placed a round dark brown shining
glandular body surrounded by a thin striated pale-coloured
membrane. Flower-buds round, acute, solid, large, dark red
and coated with a sticky substance; bracts reniform broader
than long sometimes suddenly and shortly apiculate and having
along the centre a band of closely packed scales.

“Flowers appear in June to August and fruit ripens in
September. They were described to me as white, and as this
together with all the other characters agrees admirably with
Hooker’s figure xviii [in Sikkim Rhododendrons] and descrip-
tion of Rh. Maddeni, I have most reluctantly had to renounce
my first impression that this lovely plant was a new species.

“ Fruit not ro-celled (as described by Hooker) but 12-celled,
bursting into 4-6 portions of one or more carpels and dehiscing
from the 12 placental plates which after a time separate up-
wards from the central axis. :

“Seeds very large for a rhododendron. Hooker in his
Rhododendrons of the Sikkim Himalaya states that this species
is confined to ‘ the inner ranges, very rare, in thickets of the
Lachen and Lachoong rivers at Choongtam.’ It is therefore
extremely interesting to find that ‘this truly superb plant’ is
by no means so rare as it has hitherto been thought, and that,
although it has taken thirty years to discover the fact, Rh.

BALFOUR—NEW SPECIES OF RHODODENDRON. 123

Maddent is one of the most abundant bushes in the higher
Manipur Hills and in our Naga Hill district. It may be said to
make its appearance in the eastern corner of Sikkim and to
be spread eastward to the higher Naga Hills and North-Eastern
Manipur.

“It was gathered in the Duphla Hills by Mr. Lister (a
collector sent out from the Botanic Gardens, Calcutta, in 1875),
very imperfect specimens being received. Griffith’s Bhotan
specimens No. 3507 most probably belong to this species, as
also those gathered by Simmons in 1855. Through the want
of interest taken in botanical science in India it is to be de-
plored that the history and distribution of so exceedingly in-
teresting a plant should have practically remained unknown
from the date of its original discovery in 1849 to the present
day.

ie It is very probable that my plants are nearer to the plant
introduced by Booth from Bhotan and figured by Hooker in
Bot. Mag. t. 5002—Rh. calophyllum. Not having seen the
flowers of that plant I rely upon foliage entirely, and as far as
one can judge from such material it might be better to regard
the Manipur plant as calophyllum. It seems likely, however,
that this species may be regarded as being a Bhotan form of
Maddeni and not a distinct species, and for both these reasons
I have considered it advisable to refer my plants to the more
typical and best known form.”

Note added 1915.—‘‘ I sent to Kew seeds of all the rhododen-
drons I was able to collect. One grown under the name Rh.
Elliottii, Watt proved to be Rh. Maddeni, and I was assumed to
have made a mistake. But here I describe Rh. Madden as a
separate species from Rh. Elliottii. I had never any doubt, and
so the labels on the seeds must have got changed either by me
or the staff at Kew. The Kew plant has been figured and de-
scribed as Rh. Maddent, var. obtusifolium (Bot. tae oe:

With reference to Sir George Watt’s note :—Rh. Elliottat is
a plant very different from Rh. M addent, Hook. f., and its char-
acters have been presented recently by, Lace and Smith in Notes
from the Royal Botanic Garden, Edinburgh, viii (1914), 214.
The Rh. Maddeni, var. obtusifolium, Hutchinson of the Bot.
Mag. t. 8212 does not appeal to me as a form of Rh. Maddeni,
Hook. f., and I note that Mr. Watson, writing of its cultivation,
says: “It differs in habit and several other characters from
the Himalayan Rh. Maddeni as represented in gardens.” As
described it differs from Rh. Maddeni, Hook. f. in the two dis-
tinctive characters to which I have referred on a previous page

—the large calyx about 1.5 cm. or more long and the pubescent
filaments of the stamens. The “Io stamens” of the descrip-
tion (both Latin and English) is a misprint; 17-20 stamens
are shown in the drawing and are present in specimens which
the Director of Kew kindly sent to me. I read no character
that would deny Sir George Watt’s identification of Rh. Mad-
dent, var. obtusifolium, with the plant here described as Rh.
manipurense.

This is one of the rhododendrons which attracts attention
by the snow-white under-surface of the rather long mature
leaves. Many of the leaves show a dingy spotting and may
take on a brown colour. This is due to the attack of an
ascomycetous fungus which spreads all through the indumentum.
The hairs of the upper stratum of indumentum are often very
long, and the delicate branches ascend as loose not interwoven
threads above the lower stratum, which forms a typical roof
over the epidermis. The short stalks of the hairs appear as so
many pillars supporting the vesicular branches spreading out
horizontally from the top, and the branches of adjacent hairs
becoming agglutinated form the smooth scintillating indumental
surface. In the chamber covered by these matted branches the
stomata project as domes above the epidermal surface.

In this indumental character of the mature leaves RA.
niphargum resembles Rh. uvarifolium, Diels (1912),* as it does in
such other features as the many-flowered compact globose truss
of flowers at the end of thick branches encircled by a rosette of
more or less deflexing leaves, the small glabrous calyx, 5-lobed
campanulate corolla, 10 unequal stamens with puberulous
filaments, thin dark-coloured ovary puberulous with very short
vesicular pointed hairs, the style glabrous slightly longer than
stamens, shorter than corolla, and ending in a stigma hardly
wider than the style itself which does not expand clavately
beneath it. Rh. niphargum has the foliage-buds and all young
parts enclosed in a snow-white indumentum—and I take it
that in nature these show up after the fashion of those of the
East Himalayan Rh. niveum, Hook. f, and the Szechwan Rh.
floribundum, Franch.—the striking beauty of which matches
if it does not surpass that of their flowers. Whether this is the

128 BALFOUR—NEW SPECIES OF RHODODENDRON,

case also in Rh. uvarifolium we do not know, because specimens
of young shoots of this species have not yet come to Europe.
The fruit of Rh. niphargum is of the narrow curved type of
capsule, and in the absence of direct evidence I think we may
conclude from the form of the ovary that the same form marks
the fruit of Rh. uvarifolium. My reference to Rh. niveum and
Rh. floribundum must not be interpreted as necessarily meaning
that these species are of the immediate alliance of the one I am
speaking of. Passing observation might suggest such a relation-
ship, but analysis brings out characters which in the present
state of our appreciation of phyletic marks in the genus seem
to question a connection, for the leaf-indumentum of Rh. niveum
as well as of Rh. floribundum is unistrate, composed of hairs
branching somewhat loosely from the base upwards—of different
shape in the two species—and constituting a somewhat woolly
surface, the pedicels are woolly, as is the small calyx, the staminal
filaments are glabrous, the ovary is coated with fasciated long
erect white hairs in Rh. niveum, with solitary long pointed
white stiff hairs in Rh. floribundum, and then the capsule is a
short straight stout one. At the same time I may note that the
Western Szechwan Rh. Hunnewellianum, Rehd. et Wilson has
the same general form of elongated leaf (only smaller), with
snow-white indumentum constructed like that of our two
species—Rh. niphargum and Rh. uvarifolium—but the calyx is
glandular and pubescent, the widely campanulate 5-lobed corolla
is glandular outside, the 10 staminal filaments are puberulous
and glandular, the ovary densely covered with fasciate hairs,
the style glandular and pubescent at the base. Apart from the
character of the glands, which nowhere shows in any of the
species previously mentioned, Rh. Hunnewellianum seems to be
a form somewhere intermediate to Rh. niveum (its ovarian
covering taking it to this species rather than to Rh. floribundum)
and Rh. niphargum and its fellows. Neither Rh. niveum and
Rh. floribundum nor Rh. uvarifolium and Rh. niphargum show
any glands, and this eglandulose character serves as a definite
diagnostic mark from the Himalayan Rh. arboreum, Wall. and
Yunnan Rh. Delavayt, Franch., two species which by their bullate
leaves with pale-coloured indumentum and the small compact
trussed flowers, the short tomentose pedicels, the small more
or less floccose calyx, 5-lobed tubular-campanulate corolla, 10
stamens with glabrous filaments, ovary tomentosely covered
with fasciate hairs, glabrous style, short stout thick capsule
take us towards Rh. niveum and Rh. floribundum.

Seedlings of Rh. niphargum have been raised from Forrest’s
seeds and are very different from the mature plant. They show
not a trace of the white indumentum even when three years

with glands of a particularly sticky character. See what I
say in Trans. Bot. Soc. Edin., xxvii (1917), 224.

rhododendrons. Flowers rose-pink with a dark-red patch at
base of corolla. Leaves glandular. F. Kingdon Ward. No.
1g06. 27.8.14. Very late for a rhododendron.

This species resembles most nearly Rh. pholidotum, Balf. f.
et W. W. Sm., from the eastern flank of the Tali Range. From
it and from all others in the Heliolepis series (see p. 113) it should
be distinguishable by the glutinous upper surface of the leaves—
Mr. Ward makes special reference to the glandular leaves, but
it is a feature that is not conspicuous in dried material—and by
the corolla, which is pilose as well as lepidote on the outside.
I do not discover any special glands on the leaves. There are the
lepidote scales which become full of red secretion as they olden
and might be the organs which cause the stickiness. This
would not be a common phenomenon on the leaf in species of
rhododendron, although the scales on the ovary frequently seal
together by their secretion the surface of the corolla-tube in
dried specimens. Mr. Tagg tells me that he has failed so far to
obtain evidence that there is natural exudation from the peltato
scales. He suggests that exudation is probably always the
result of pressure from the outside. If this be so some other
origin for the stickiness of the leaf must be searched for in
Rh. oporinum.

The rich golden-brown tint of the under-leaf indumentum
is a conspicuous distinctive character of Rh. phaeochrysum
amongst like forms, of which the likest are Rh. Beesianum, Diels
and Rh. fulvum, Balf. f. et W. W. Sm. These three species
cannot be mistaken one for the other. Rh. lacteuwm, Franch.,
which is also an ally, has the rosette-haired indumentum of Rh.
Beesianum not the matted-haired type of Rh. phaeochrysum,
and then it has broad obovate leaves, yellow and creamy-yellow
flowers. The only other species which I mention here as an
ally is Rh. Traillianum, Forrest et W. W. Sm., and it has the
powder-like indumentum of Rh. Beesianum not the felted
indumentum of Rh. phaeochrysum; also the indumentum cf
Rh. Traillianum is at first grey-green and turns to red-brown in
the older leaves.

Rh. pholidotum is like Rh. secithin: but the puberulous
bases of the exserted style and stamens of that species are very
different. Its nearest ally is perhaps Rh. brevistylum. There
should be no danger of confusion of Rh. pholidotum with any
other species in the Heliolepis series (see p. 113). Apart from
flower-colour distinction, it wants the viscid upper-leaf surface
and the hairs outside the corolla of Rh. oporinum; it has not
the narrow-based leaves of Rh. brevistylum ; it has not the large
leaves and distantly placed scales of Rh. heliolepis ; the size of
leaf as well as the small campanulate—not tubular-campanulate
—corolla tell it at once from Rh. plebeium; Rh. fumidum has a
green spotted corolla, a calyx epilose outside and an epilose
ovary ; Rh. rubiginosum has conspicuously biform under-leaf
scales. It is the Middle West Yunnan (Tali) representative of
the series, and is in cultivation.

This fine species is one of the rhododendrons with fairly
large leaves, the under-surface of which is clad with a bright
white indumentum. The conspicuous character for diagnosis
of Rh. pilovittatum is that which gives it the name. The middle
line of each petal is occupied by a band of curled hairs which
run right down from the free lobe to the base of the corolla-
tube. The hairs often fall off early.

A well-distinguished species, the most southerly of the
Heliolepis series, findin rhaps its nearest relation within
the series in Rh. heliolepis itself. Like that plant it has broad
leaves, but the surface scales are much more numerous and much
closer set and give a diagnostic mark at sight. Another easily
seen differential character is the tubular-campanulate corolla
and the shorter ovary. Altogether Rh. plebetum is a more
lepidote plant than Rh. heliolepis. a

The Lae is in cultivation, raised by Mr. J. C. Williams of
Caerhays Castle from seed collected by Forrest.

This seems to be a widespread species of rhododendron in
the N.E. of Yunnan, and it shows much variation in form of
foliage. Specimens with acuminate leaves certainly look very
different from those with leaves rounded at the apex, but the
considerable number of specimens I have had for examination
show all stages of transition. The somewhat isolated brown
peltate scales on the glaucous green under-leaf surface is
characteristic, and then the nonfasciculate inflorescence, the
elepidote corolla, the slender filaments of the stamens and long
slender style give a combination of characters that I find
nowhere else. The species I take to be one of the small-
flowered ones which are more or less allied to Rh. rigidum,
Franch., some of which have not been described. I am not
yet in a position to fix precisely its relationships.

larger flowers than the former and smaller ones than the latter.
It differs from both of them in its under-leaf surface, which
always shows the purple reticulum of the ultimate venation
although this is:submerged in the leaf-lamina. In both the
other species the epidermal papillae are developed to a degree
sufficient to mask the venation, and it is this which gives the
very white aspect to the under-leaf, particularly in Rh. discolor.
Rh. rasile is likest to Rh. diaprepes, and is readily distinguished
by the eglandular under-leaf surface and the very glandular
outer surface of the corolla.

magnificent plant. Without doubt a microform of the
type of Rh. Dalhousiae, Hook. f., but it has a much larger corolla
and then the broad red bands on the outside of the corolla and
in the median of the petals mark the plant at sight. These
flower features are not the only differential ones. I find no
trace of the surface bristles of the young leaves of Rh. Dal-
housiae on those of Rh. rhabdotum, the upper surface of the
mature leaves is smoother in Rh. rhabdotum, and the indumental
scales are much more numerous. Specimens of what I take to
be the true Rh. Dalhousiae, gathered in Bhutan by Cooper, are
from a lower altitude—none over 6000 ft.—than are those of
Rh. rhabdotum, which was found at 8000 ft. We have no fruit
on Cooper’s specimens which were collected in May, and the
introduction to cultivation of Rh. rhabdotum awaits the effort
of some explorer in the future.

This species, of which seedlings have been raised from
Forrest’s seeds, is one of the Selense series, and promises to be
an acquisition to our gardens. It is a low-growing shrub with
small neat leaves and bears many-flowered trusses of flowers,
the colour of which is probably pink, and it produces narrow
sickle-shaped dark purple fruits. Forrest’s specimens are all in
fruit or passing into fruit, and the flowers available are shrivelled
around the ovaries beginning to develop into fruit. Some
modification of the description given above may be necessary,
therefore, when more satisfactory flowers are forthcoming.

In Forrest’s collection are two plants which resemble Rh.
rhaibocarpum, but which in default of better illustration 1
hesitate to identify with it. They are ticketed :—

Lat. 28° ro’ N. Open rhododendron forest. Shrub of 8-10
ft. Foliage only. G. Forrest. No. 13,560. Oct. 1914.

Both of them have leaves approaching more nearly the
elliptic, and the remarkable biform indumentum of shoot and
leaf-petiole seen in Rh. rhaibocarpum does not show on them.
There are, however, no young spring shoots, and we know this
indumentum soon falls off. No. 12,950 wants the yellow cauli-
flower-glands of the leaf under-surface. No. 13,560 is specially
noticeable because of the russet autumn-tint of the older leaves.
Coming from the Kari Pass, as does Rh. rhaibocarpum, No. 12,959
may be merely a local divergent from the type. No. 13,560 aS
a Shweli-Salween divide plant is more likely to be distinct.
From the specimens of both of them good seeds have been
extracted and one may hope for germination.

_ There is yet another plant represented in Forrest’s collec
tion by two sets of specimens (in foliage only) which also
belong to the Selense series. The tickets on the specimens

These are of the same species, but I cannot match them with

A larger plant than Rh. Sheltonae, Hemsl. et Wils. in
all its parts. Apart from size it differs in the complete
glabrousness of the older leaves. The young leaves have on
their upper surface as they open from the bud a few scattered
hair tufts which soon disappear leaving no trace ; on the under
surface there are no hairs or glands. Consequently, the older
leaves -have both surfaces entirely bare of appendages. In Kh.
Sheltonae the under surface always shows red or yellow glands
as minute points all over the surface. The lobes at the base of
the leaf are not so rounded here as they are in Rh. Sheltonae.
Then the corolla is always red-spotted in Rh. rhantum—hence
its name. The species is one of a difficult complex, which will
require much examination of living plants before its legitimate
microforms can be accurately diagnosed. We have seedlings
of Rh. rhantum (No. 10,075) raised from Forrest’s seed, presented
by Mr. J. C. Williams, Caerhays Castle, and we may look to
having flowers of the species in a few years.

A species neatly waa to Rh. bullatum, Franch. and to Rh.
Edgeworthii, Hook. f£., but its leaves suffice to distinguish it at
a glance from these species. They are larger and want the
bullation of the surface which is so marked a feature in the
leaves of these allied forms. The bullation is due to the pouching
upwards of the lower leaf-surface between the veins which appear
on the upper surface to be below the level of the leaf-surface at

148 BALFOUR—NEW SPECIES OF RHODODENDRON,

the bottom of a groove. In Rh. sciaphilum there is sometimes,
particularly towards the margin and top of the leaf, a suggestion
of this, but generally the surface is smooth and the primary
veins have no groove above them. And then Rh. sciaphilum
is wanting, as Mr. Kingdon Ward tells us, in the character
which is so strongly developed in the allied species—fragrance
of the flower.

The discovery of Rh. sciaphilum in the Naung Chaung Valley
in E. Upper Burma establishes an interesting geographical link
between the Himalayan and the West Chinese flora. The
series to which it belongs we may speak of as the Edgeworthii
series, after the well-known Himalayan Rh. Edgeworthi, the first
described of the species now placed in it.

The description by Franchet in 1887 of Delavay’s specimens
of Rh. bullatum and Rh. Bureavi put on record that the type of
Rh. Edgeworthii, before then known only from Sikkim and Bhutan
through the explorations in the middle of last century of Sir
Joseph Hooker, of Griffith, and of Booth, had a spread far east-
wards in the western region of Yunnan. Then the distribution
was carried farther eastwards by the discovery by Maire of
Rh. cruentum in N.E. Yunnan, and now Ward’s plant RA.
sciaphilum comes to show us that the type is to be found in the
region between the Himalayas on the west and Yunnan on the
east, and suggests that there may be other forms of it yet to be
discovered over this broad unexplored area. In the following
list I give the names of the five known species of the Edge-
worthii series, the general distribution of each species, and the
name of its discoverer :-—

To Rh. Edgeworthit, which has been in cultivation since 1849,
we now can add Rh. bullatum and Rh. Bureavi as plants in
our gardens.

The Edgeworthii series is marked by vegetative and floral
characters illustrative of a true natural phylum. The plants
seem to be frequently though not always epiphytic. Probably
in their case, as in that of others, altitude may determine habitat
of the plants and there can be little doubt that their epiphytism
is favoured by their partnership with a fungal symbiont.

The striking feature of all the Edgeworthii series is the
golden brown or red indumentum which completely encloses
with a thick felt every aerial radial organ of their bodies—
stem—pedicels—petioles—ovary—base of style—fruit—and
covers the under surface of the mature foliage-leaves and more
or less that of the calyx. This indumentum in all the forms to
a casual observation seems to consist of closely interlocking hairs
Which can be readily removed, But similarity in general form
is arrived at by different paths, Closer examination shows that
this superficial ‘ wool” layer is not always made of the same
kind of thread, and, moreover, that it does not constitute the
whole indumentum, which is bistrate. C. B. Clarke * has noted
the bistrate character of the: indumentum of the leaves of Rh,
Edgeworthit. He says: “There are round glandular scales
beneath the wool of the leaves.”

There are really two modifications of bistrate indumentum
in the series. One found in Rh. bullatum, Rh. Edgeworthit, and
Rh, sciaphilum, and we may designate it A. form; the other
in Rh. Bureavi and Rh. cruentum, and we may call it B.
form ;—

A. form.—The upper stratum in this indumentum consists
of many very long unbranched hairs, each tapering from a
thicker base to a fine point. The base 1s composed of many
elongated narrow cells, each with a thickish wall, lying parallel
and forming a cord—fasciated, as it were—often with a core
and a peripheral sheath; the number of these component cells

150 BALFOUR—NEW SPECIES OF RHODODENDRON.

in a transverse section diminishes upwards until towards the
top there is but one cell. Almost from the base the hair curls
upon itself in the same way as a tendril curls when it fails to
find a support, and it is the intercurling of the several hairs that
gives the peculiar resilient character to the whole superstratum
of indumentum. Beneath this upper stratum of hairs lies an
under stratum of stalked peltate scales on every part where
hair-indumentum is found. They are not confined to the under-
leaf surface. These peltate scales, at first white and translucent,
become infiltrated later with red secretion, and they look like a
series of Peziza-cups spread on the epidermis. And then be-
neath the peltate scales is to be found a remarkable develop-
ment of long rod-shaped epidermal papillae, each rod being
coated outside by large wax-granules.

form.—The hairs of the upper stratum of indumentum
are somewhat different. They are fewer, very thick-walled,
quite fibre-like. Each has a stout multicellular base, and
then extends with a curious jointed character sooner or later
branching into long fibre-like threads which do not curl so
definitely as those in Form A. yet are conspicuously interwoven.
In the under stratum we miss entirely the peltate scales. These
are replaced by glands which have multicellular stalks short or
long and rounded or oblong heads. And then there are no
epidermal papillae.

The contrast is interesting. In both a layer of still air is
secured by a thick covering of hairs, in one case unbranched
and many, in the other branched and fewer; and then, as 4
check to the transpiration, are peltate scales and wax-coated
epidermal papillae associated with the unbranched hairs, glands
and no papillae with the branched hairs; the latter combina-
tion perhaps allowing more perfect distribution between fewer
hair-stalks of the emanation from the glands.

I am not prepared to maintain that all the plants cited in
the table under Rh. bullatum are really that species. - Their
distribution is against identity. It is rare to find a species
running from the dry Chungtien Plateau south to the moist
region of Tengyueh, and the specimens themselves show difference
which lack of material alone makes it difficult to appraise. I
do no more here than point out the possibility of more than one
species being included under the name, and leave over dis-
cussion of the forms until after additional illustrative specimens
have been obtained.

Rh. cruentum has not been described adequately, and I
therefore give a description of it here, bringing in also -
of its ally Rh. Bureavi, so that their relationships may be
appreciated :—

So far as Léveillé’s description goes, there is nothing by
which to distinguish his species Rh. cruentum from Rh. Bureavi
and other members of the Edgeworthii series. M. Léveillé has,
however, been so kind as to present a portion of his type RA.
cruentum to the Herbarium of the Royal Botanic Garden,
Edinburgh, from which I have learned what was before him
when he diagnosed his species, The plant is the same as one
of which we obtained specimens from Abbé Maire in 1913, and
from this materia] and M, Léveillé’s gift I have drawn up the
description given above.

Rh. cruentum is a very near ally of Rh, Bureavi, Franch., but
shows divergences which forbid its inclusion in that species.

The foliage and shoots are quite alike in the two species,
and are most characteristic in their red thick indumental cover-
ing—only in Rh. cruentum the leaves do not appear to reach
the size of those of Rh. Bureavi, and the petioles are thinner and
longer. The most easily seen distinction between the species
is the calyx. In Rh. Bureavi the calyx has large membranous
lobes with flabellate veins, and the tomentum is mainly formed
at their base. In Rh. cruentum the calyx-lobes are much smaller,
thick and leathery, and their outside surface is covered all over
with the indumentum. Another apparently good diagnostic
character is the style, which in Rh, Bureavi has at the base

BALFOUR—-NEW SPECIES OF RHODODENDRON. 153

dense hair tufts with some long-stalked glands; in Rh. cruentum
the style is glandular and floccose throughout nearly its whole
length. Then I find that in Rh. cruentum the corolla-tube is
densely pubescent inside; in RA. Bureavi there are fewer hairs
but intermixed with them are many clavate glands. On the
posterior side are many crimson spots which do not appear in
Rh. cruentum.

The flowers as a whole of the two species differ in size—
those of Rh. cruentum being much the smaller. At same time
I find some variation in flower-size of this species, but the flowers
never seem to attain the size of those in Rh. Bureavi.

The finding of Rh. cruentum in N.E. Yunnan gives an
interesting extension of distribution to the Bureavi type. We
have Rh. Bureavi from E.N.W. and Rh. cruentum from N.E.
of Yunnan. The localities, stir eS though they are by the
breadth of Yunnan, are within the Yangtze basin, and when
we get to know more of the intervening area one or other of
them or related forms may be found. Hemsley and Wilson * give
a record for Rh. Bureavi in Szechwan under Wilson’s number
3954. The number is not given in Wilson’s list of the plants
of the Veitchian expedition, and I have not seen the specimen.
I should not expect Rh. Bureavi to occur in the area of Szechwan
which Wilson explored; the occurrence of Rh. cruentum would
conform with experience of other species.

with thinner twigs and leaves which colour beautifully red in
autumn. The scales on the leaf upper surface are contiguous
and soon dry up, appearing as a dirty white or grey scurf on the
older leaves. Occasionally the umbo of the scale has a resinous
content, but the scales never stand apart as glistening spots on
a shining green surface as they do in Rh. lepidotwm. The scales
on the under-leaf surface, too, are closer set and usually more
or less punctulate. The leaf-shape is always on the side of
elliptic, whilst in Rh. lepidotum it is on that of lanceolate. The
pedicels are shorter, the calyx is smaller and its lobes not so
separate as they are in Rh. lepidotum. The broad rounded
corolla lobes have one mid-vein, whilst in Rh. lepidotum the mid
vein is accompanied by two lateral ones running up nearly to
the top. The fruit is smaller.

The species was introduced by Mr. Bulley by seeds collected
by Forrest in 1906. From seeds presented to the Royal Botanic ,
Garden, Edinburgh, by Mr. Bulley, plants have been raised
which first flowered in rgIo.

Kingdon Ward collected in July 1912, under No. 905, on the
cliffs and rocks of Ka-gwr-pw, at an altitude of 13,000-14,000
ft., a crimson - flowered dwarf rhododendron which resembles
closely Rh. sinolepidotum, but the petaline lobes are hardly in
character for they are elongated ovate. There are other minor
differences, possibly local divergences, from the specific type
and giving no sufficient characters for separation. I mention
the variation in view of a complete analysis of the Lepidotum
series at some future time.

This is a distinct species of the Stamineum series, easily
recognised from Rh. stamineum, Franch. by its very much
larger flowers and included stamens and style. It exhibits
more strikingly than most species of rhododendron the juvenile
phase of its life-history. _The young plantlets are deep | claret
red all over and have stems, petioles, midrib, and margin of the
leaves densely covered with white bristles, some of which end
in capitate glands. So unlike is the plant in this state to the

adult that an observer might well question at first their being
the same plant. None of Forrest’s specimens provide foliage-
leaf buds, and I am unable to say what the features of the
evolution of the leayes in the adult are, but the traces of juvenile
hairs on the several parts of the adult leaf and the occasional
presence of setulae indicate that the leaf in its younger stages
is setulose. Although the leaves of the adult are green, there
is often a tinge of reddening in the petiole and midrib, and
at times the lamina may show a sort of metallic purpling remi-
niscent of the juvenile phase. All the leaves, even the most
green, yield on boiling a dark purple red almost black solution.

The calyx is noteworthy. As a rule it is minute with 5
deltoid lobes hardly one millimeter long, but occasionally one
of them grows out into a long narrow membranaceous riband
over one centimeter in length and sometimes a second one may
also do so. Occasional intermediate stages may be seen. A
calyx with all five calyx lobes having this riband or thread form
is characteristic of Rh. nematocalyx, Balf. f. et W. W. Sm. (hence
its name), which belongs to the Stamineum series also and is
not far removed from Rh. oxyphyllum, Franch.

The species is in cultivation and flowered in 1917 with Mr.
Magor in Cornwall, who kindly sent to me the flower. Mr. J. C.
Williams of Caerhays Castle also sent to me living specimens
of the plant.

This hard-leaved species does not appear to have many

flowers are small and few in a truss, and the base of the trusses
is enveloped in the bracts. The red colour of the twigs may be
perhaps its most effective character.

This is a most distinct species, and if the flower tint is only
right the plant should be an acceptable one in gardens. It is
most floriferous, and in the dried specimens the flowers retain
more colour than is the case in kindred species. In habit it
recalls the Rh. yanthinum of our gardens, but the thickly-set
scales of the under-leaf indumentum in that plant and its allies
readily distinguish it and them. The scattered scale-indu-
mentum on the under-leaf surface resembles that of Rh. rigidum,
Franch., but Rh. sycnanthum may be recognised by absence of
the wax bloom on the leaves, the total absence of hairs from
young twigs, petiole, and groove of midrib on upper leaf-surface.
This surface from the first is glabrous, not a hair appearing on
it even in the groove of the midrib or in the groove of the petiole,
nor is there a peltate scale. The few cilia which fringe the leaf-
margin in bud fall off with expansion from the bud. Two other
characters separate Rh. sycnanthum from Rh. vigidum—the
flower-pedicels and calyx are lepidote and the flowers them-
selves larger.

There is no doubt about the identity of Ward’s Burmese
plant (No. 1568) with Forrest’s plant (No. 12,065) of the rhodo-
dendron forest of the Shweli-Salween divide. Nor do I think
the identification with these of Forrest’s fruiting plant (No.
8923) can be questioned. Yet the habitats of the Burmese
and Yunnan plants are very different. Its growth as a shrub
in Yunnan may be correlated perhaps with its habitat—rocky
slopes. The white wax-coated underleaf is certainty more a
character of open rocky slopes than of damp rain forest.
Forrest’s specimen (No. 12,064) must also, I think, be placed
here. It has all the technical characters of the species but has
smaller leaves.

The very white-grey under-side of the leaf is a striking feature
of the species. The grey surface is composed of short cupola-
like epidermal papillae coated with wax. The peltate scales
have hardly any stalk and do not arise in a real pit of the sur-
face, but only on a slight depression out of which they project
and show a large broad central boss with a broad wing.

The whole characters seem to place this species in the series
with fasciculate inflorescences to which Rh. Augustinii, Hemsl.
and such like forms belong. The series is a rare one in West
Yunnan, and I do not find any species which I would select as
of particularly near affinity to Rh. zaleucum. But I have not
had as yet material or opportunity to study satisfactorily the
members of the series.

A species closely allied to E. indicum, Clarke and E. latert-
florum, Clarke, differing from both in the calyx. These three
plants are undoubtedly congeneric, and differ markedly in the
corolla from the typical members of the genus. E. indicum
has been referred to the American Thyrsacanthus (otherwise
Odontonema), to Asystasia, to Mackaya (South African), and
has been made the type of a new genus by Lindau, Odonto-
nemella. There is much to be said in favour of Lindau’s grant
of generic rank.

This is an interesting extension into China of this rare
genus. Two species were previously known, both believed to
come from Burma. Their exact habitats are unknown. The
present plant is much the finest of the three. The flowers of
this genus show great reduction in the size of the labellum and
the absence of staminodes.

ADDENDUM,

My thanks are due to the Director of Kew for the loan of
Chinese material of Strobilanthes. These sheets had already
been examined by the late C. B. Clarke, who affixed manuscript
names to several of the species. These names I have adopted
and have given descriptions. Some of these species are not
represented in the Edinburgh Herbarium, and my further thanks
are due for permission to include descriptions of these in the
above series. I am thus enabled to publish the new species

To Mr. G. Forrest we are indebted for the introduction of
this genus to cultivation. From seed- collected by him Mr.
Williams, Caerhays Castle, Cornwall, raised plants, one of which
he communicated to the Royal Botanic Garden, Edinburgh.

in several respects from that species, and above brief description
has been drawn up from the fresh plant with the primary object
of embodying the chief diagnostic features.

Examination of Hancock’s specimens proves that the figure
