ARBORETUM

Towards A Better Understanding

By Dale Kloppenburg

Subject: Hoya merrillii Schlechter

For a long time now I have been concerned
over the species we have labeled as Hoya
merrillii Schlechter. The original clone of the
species in question was collected by Ted Green
and myself in 1981 from Professor Juan
Pancho’s yard and labeled with the number
81 1 00. Even today in the Philippines, the US and
possibly elsewhere, this and similar clones are
called and labeled as H. merrillii. Professor Juan
Pancho also identifies this species as H. merrillii.
What has perplexed and bothered me over the
years is that Schlechter’s drawing on the
Herbarium Type sheet in the Berlin Herbarium
shows a flower with raised outer coronal lobes.
The coronas of the flowers on the species
labeled with the number 81 1 00 (the species we
have been calling H. merrillii Schitr.) is
essentially horizontal with the inner lobes
slightly raised, differing very obviously in this
respect from Schlechter’s drawing.

There arethree Philippine species in our living
material that have similar, though different
foliage as well as other characteristics. In
addition the flowers on all three are yellow, of a
similar shade, with the petal edges and apex
rolled under. The umbels and individual flowers
look remarkably alike. The three species I am
referring to are #81100, which has unusually
deep glossy green foliage, the plant we know as
H. sp. Cebu and H. pentaphlebia Merrill. It is
fairly certain that the identity of H. pentaphlebia
Merrill is correct. That leaves only two species
out of the three that are in question. A
determined "Lumper" would probably say all
three species are one and the same. It is clear
however, on close examination that the coronas
of each are distinctive and quite different in the
three species. In addition the flowers and flower
parts are different sizes and shapes. The
poliinaria of H. sp. Cebu is much smallerthan H.
sp.81100.

After much study, I have come to the
conclusion that the plant we know as H. sp.
Cebu (collected on the Philippine Island of
Cebu) is H. merrillii Schitr. In addition, I have

determined that the other species in question
(#81 1 00 or other numbered clones of the same
species) is H. quinquinervia Warburg. Both of
these species have nice glossy foliage, and
Warburg correctly observed that the foliage of
H. quinquinervia was unique. ..it is in fact
outstanding with a beautiful waxy gloss that
appears to have been buffed to a high shine. The
foliage of H. merrillii Schitr. (H. sp. Cebu) is a
gorgeous glossy green when young but takes
on a definite yellowish cast as it ages.

likewise with leaves 5 nerved, but more
elliptical and not pointed but apiculate, as
well as nearly 10 cm. long and with the
peduncle 1 mm. thick, unfortunately the
'lowers were dry having fallen and
became damaged.

Discussion

I feel that the key word in the beginning
of this description is "unique". The foliage
of our #81 1 00 and similar clones are
unique in the glossiness and deep green
waxy foliage that certainly stands-out.
These species are easy to distinguish
because of this character, they
immediately stand out from other
Philippine species, even other hoya
species. It has been inferred that the
^ecies was based on too little material.
The misreading of Warburg’s German
reference to a species from Davao,
Philippines in which the flowers had
dropped to the ground i.e. Herbarium
sheet #14386, has led to this incorrect
conclusion. It is evident that Warburg had
access to sufficient live material ancT
gave a rather detailed description with
adequate measurements and comments.

The flowers are yellow minutely sprinkled with
purple as stated by A.D.E. Elmer in Leaflets of
Philippine Botany 10 (1938) 35991.

Questions
Sc Answers

Question: What causes the purple rings and
freckle-like spots on the backside of many of my hoya
leaves, is this some type of disease that I should worry
about? D.W.

Answer: I had to ask this same question awhile
back, because I didn’t know what caused it either. I
was told that it is caused by a spilling over or overflow
from an excess of chemicals that are absorbed by the
plant, either from the soil itself or from chemicals that
are added in the form of fertilizer or micro nutrients.
The chemical most commonly to blame is magnesium.

Question: I have a shooting star hoya that has
been beautiful and has bloomed almost constantly for
over two years. It is now getting so tall and lanky that
the plant is no longer pretty, but still keeps blooming.
Should I prune it while it is in bloom. ..and if so, how far
should I cut it back? N.S.

Answer: By all means, prune it right away. It can be
cut back to within a few inches of the soil line, but
allow several sets of leaves to remain on the plant.

This will force new growth in the form of side
branches. Your plant will be bushier and in time will
have all these new branches to form flower buds. By
the way.. .don’t throw those cuttings away, reroot them
and grow them into flowering size plants for your own
enjoyment or for gifts, plant raffles or whatever.

Question: I’m having a terrible problem with spider
mites this year. I can spend all day swabbing their
webs out of my plants but within a few days most of
them have all been rebuilt. My plants look terrible and
the hot house looks like something out of a halloween
movie with spider webs everywhere. What can I use to
get rid of these pests? W.J.

Answer: You may very well have some spider
mites. ..but I can tell you without even giving it much
thought that spider mites isn’t the guilty party that is
building webs all over your hot house. If you had
enough spider mites to build as many webs as you
indicate there are, you wouldn’t have one single plant
left alive. Furthermore. ..spider mites build extremely
fine, very small webs without any pattern to them at
all. They actually look more like shredded fiber glass
than webs, and you can usually see mite excrement in
them. Spider mites use these small webs to get from
one part of a single plant to another part of that same
plant. On the other hand, regular old everyday eight

legged spiders of most species can and do build huge
blocks of very intricate webs to trap their prey and to
get from one side of a building to the other side very
quickly without having to go over and around every
obstacle that might be in their way. I suspect the real
culprit in your case is some very common garden
spiders. ..maybe several different kinds. They probably
moved into your hot house to take advantage of any
easy meal that happens to venture into their webs. I
am a gardener who had to learn to live with spiders
because I know the good that they do for us by eating
harmful pests that would otherwise destroy our plants.

I know they are strictly carnivorous, they don’t eat
plants or flowers, just bugs and each other.. .they are
probably the best friends a gardener can have and I
can give others good sound advice for letting them
live but heaven help me...l would literally rather run
into a snake than a spider.

Question: I’ve heard a lot about preserving hoya
flowers for study. I guess these are wanted by the
scientists and the people involved in research. I’m
perfectly willing to share my flowers with others who
want to study them but I don’t know where to start.

Are there particular flowers that are wanted? How long
should they be open before they are picked off for
preserving, and what do I preserve them in? Who
should I send them to? C.P.

Answer: Let’s take first things first.. .Yes particular
flowers are wanted and needed. Hopefully I will soon
have a list of flowers that have yet to be examined.
When I do, I will list them in Fraterna. They should be
picked within 24 hours of opening and placed in a few
drops of preserving solution in a tightly capped bottle.
Some use Isopropyl alcohol (plain rubbing alcohol). I
prefer a solution of 10% formalin that most
pharmacists will make up for you. The trick is to use
only a few drops of whatever your using. ..that is all
that is necessary. Too much solution will make the
flowers soggy and hard to work with, it will also
remove all the color from them, and we want them as
close to the natural color as possible. If the umbels are
very small, it would be nice to have the entire umbel. If
the flowers are large, a few of them will do nicely, try
to get the full length of pedicel so we can get the
measurements. You can send them to the IHA office at
P.O. Box 5130, Central Point, OR 97502. 1 will disperse
them to whoever wants them for study.

Just Little Clay Pebbles

Anytime I hear about a miracle plant cure, a
marvelous potting mix, an aphid eradicator, or
something that will bring on a bloom bonanza...!
always Just Gotta T ry It! Well, almost always.

A couple of years ago 1 was talking to member
Richard Dobson on the phone and he happened to
mention a product that he had been using to grow
some of the very difficult hoyas. When I say difficult...!
mean difficult for me. Some growers have phenomenal
success with plants that die if I even look at them. I’d
hate to tell you how many H. darwinii, H. linearis, H.
microphylla, H. campanulata, H. imbricata and H.
curtisii I have killed over the years yet I have seen
beautiful specimens of all these plants growing
beautifully for others. I told Richard that I would give
anything if I could just grow some of these challenging
plants to maturity even if I never saw a bloom. That’s
when he told me about this product that he called Leica
Stones (or Leca Stones) and said he had experienced
very good results with it. We struck up a bargain and
did some trading. ..plants for Leica Stones. 1 guess in
my mind I had envisioned fascinating shaped stones
pulsing with some kind of strange energy that would
catapult my plants to "Jack & the Beanstalk" sized
plants overnight.

Sure enough, within a few days my sack of Leica
Stones arrived as promised. I tore open the package
and had to laugh. They were just little clay pebbles and
I didn’t know what to do with them, so I stuck them in
a cupboard and forgot about them. Now Vicki Graves
of "Vicki’s Exotic Plants" is more of a phone talker than
I am. She had been talking to Richard also and talked
long enough to find out what to do with her sack of
stones. A few months later she was over visiting and I
mentioned that I needed some starts of plants that I
had lost. Since her and I usually have trouble with the
same plants, I hadn’t thought about asking her if she
had them, I just assumed that I would have to order
them from someone else. When she told me she had
nice sized plants of all those that I needed to replace I
was surprised. How in the world could she get them to
grow when neither one of us ever could before. Her
answer.. .Oh, I growthem in Leica Stones now. With me
sputtering.. .you mean those little clay pebbles? How?
what do you do with them? Right then I got a lesson on
how to grow plants in little clay pebbles.

The method is purely hydroponic or water
gardening but with a twist. You must use a clay pot for
this method because the pot must be able to breathe
and also take water and nutrients in through the pot
walls as well as through the bottom. Soak your pots
and the Leica Stones in water overnight. Fill your pots
almost full with the stones then place your cuttings into
the pot making sure that at least one pair of nodes is
covered by the stones. Place your pots in a shallow
container of water in a bright but not sunny position.
Do not let the container go dry while your plants are
rooting. As soon as your plants have a good root, you
may move your plants to a brighter area and start using
a very mild fertilizer solution in your bottom container
(I recommend a few drops of Schultz liquid in a quart
of warm water). When your plant is growing well, it will
not hurt to let the container dry out for a few days. ..the
stones will still contain enough moisture to keep your
plants from wilting. Occasionally you will need to run
clear water through the pots to remove fertilizer salts.

I can honestly say that I have never seen plants take
hold and root and grow as well as they have using these
little clay pebbles. I have not lost one single plant or
even one unrooted cutting with this method. I now have
H. linearis, H. campanulata, H. schneei, H. curtisii, H.
vitiensis, H. megalantha and some others that I’m not
sure of their identification. With this method I may get
to see some blooms soon, then perhaps we can
identify them.

I called the company that sells them to get some
prices and other information. The company is
Fensmore Inc. Plant Systems, P.O. Box 21 88, Apopka,
Florida, 32704-2188. Phone (407) 886-2367. The retail
price of a 5 quart bucket at present is $9.95 postage
paid, they will accept Visa or Master Card. They also
sell wholesale to dealers with fed ID # in minimum
quantities of 45 liters, the freight on this quantity is
double the price of the product.

From the literature that came with my order, I
gathered that they also sell special pots, plant nutrients
etc. You may want to inquire about other items that
they sell.

H. waymaniae Kloppenburg

Hoya waymaniae Kloppenburg sp. nova

Typus cultivated atFresno.CA., USAfromclone
obtained from the Sydney Botanical Garden by
Ted Green in 1988 or there about. Holotype: DC #
11. Section Acanthostemma (Blume)
Kloppenburg. This species fits the delineations for
the Subsection Angusticarinata Kloppenburg "
corona foliola lateribus rotundato anguste
carinata". The side lobes are exceptionally narrow,
however the corona segments are very different
from the long narrow segments of the subsection
type Hoya diptera Seemann, Hoya eitapensis
Schlechter or Hoya flavida Forster & Liddle. Here
the segments are oval, broad and short, the outer
apex is obtuse to subcordate.

Frutex epiphyticus, ramis pubescentibus; folia
opposita, succulenta, ovata, utrinque pubescenta;
petiolo ca. 1.5 cm. longo, pubescenta; umbellae
axillares; pedicellis 2.7 cm. longo, pubescenta;
corollae lobis revoluta, intus pubescentibus;
coronae segmentis erectis; floribus aurantiacis.

Hoya waymaniae like Hoya diptera Seemann
has narrow side lobes but differs in having ovate
coronal segments and the side lobes do not meet
at the outer apex but do meet lower down on the
outer surface at which point the lower channeled
groove begins. In addition the corolla here is

revolute like the species in the Subsection
Externatae K/oppenburg thus differing from Hoya
diptera Seemann.

Stem: stout, rigid, succulent, pubescent, terete,
rooting especially near the center of the
internodes, rusty pink colored. Nodes enlarged,
somewhat flat; internodes 2-1 0 cm. long; copious
milky latex present.

Leaf Blade: thick, rigid, succulent, both
surfaces finely pubescent especially so with the
lower surface. 5-9 cm. long, margins very undulate
3-5 cm. wide, enervis, edges rough with small
bumpy thickened protrusions, much pinkish
pigmentation. With a linear imbedded leaf gland
present.

Petiole: heavy, 1.5 cm. long x .4 cm. diam.,
twisted, somewhat flattened on the upper surface
(but not grooved) otherwise terete, pubescent.

Pedicel: 2.0 cm. long x 0.14 cm. diameter,
terete, curved with scattered hairs and fine
pubescence.

Calyx: elliptic triangular. 0.8 cm. x 0.16 cm. at
widest portion near the base, surface glabrous,
outer punctate, ligules present.

8

Ovaries: dome shaped 0.19 cm. tall with the
paired base 0.12 cm. broad, glabrous, shiny.

Corolla: revolute, outside glabrous, inside
finely pubescent with apex glabrous, pentagonally
thickened and sunken under the corona with
stellate hairs around the extremely short tube,
deeporange incolor. SinustosinusO. 50cm.; sinus
to apex 0.57 cm.; sinus to center 0.40 cm.; apex to
center 0.82 cm., making the flattened flower
diameter 1 .6 cm.; widest 0.45 cm.

Corona: Very thick and upright, ovate, outer
lobe of segment very broadly rounded to
subcordate, inner lobe very short laterally
compressed (dentate), narrow bilobed side
extensions well down on side of segment meeting
below the outer apex with sides forming the
coronal lower groove. Anthers membranaceous,
triangular long, exposed in the center of the flower,
stylar column usually visible in the center. Apex to
apex 0.22 cm.; apex to center 0.30 cm.; 0.18 cm.
wide near outer apex; thick ca. 0.18 cmi.; color
clear deep orange. Stylar head broad dome
shaped.

Pollinarium: long narrow upright pollinia 0.43
mm. long X 0.11 mm. at widest, with sterile pellucid
edge from the inner apex all the way to the
translators, with narrow triangular vacuole widest
at the base; translators 0.27 mm. long arising at
right angles to the retinaculum bending upward at
right angles 0.07 mm. from attachment point,
variable in thickness but generally ca. 0.04 mm. on
the exposed side, cupped (on inner end around
the pollinium), granular surface; caudicle clear,
linear (long and narrow) with a semi bulbous end
ca. 0.05 mm. diameter; the retinaculum is relatively
very small ca. 0.1 mm. long including the bifid
extensions, head 0.45 mm. wide.

Hoya Waymaniae Kloppenburg has a very
distinctive pollinarium, it could be separated from
all other hoya species on this character alone.

It is an honor to name this distinctive and
beautiful hoya species for Ann Wayman, editor of
the International Hoya Association’s official
quarterly bulletin, "Fraterna". Her presentations in
this publication are carried out in a professional
manner, always thoughtful and thorough in
content. She is a superior plant person, constantly
bringing those difficult hoyas into bloom, and
finally capturing their beauty on camera for all to
enjoy a hundred years from now.

Dale Kloppenburg

Editors Note: The flowers of this species were
a photo feature in "Fraterna" 1st quarter 1995. In
the article that accompanied the photo, I
mis-stated that the original clone of this plant (H.
sp. 85-1 981 ) wascollected by Ted Green in Borneo
in 1985. I have since received a letter from Ted
straightening me out on the real story behind the
acquisition of this plant. A.W.

Ted says. .."I didn’t collect this plant in Borneo -
I saw it there later, but my original piece came from
the Sydney Botanical Garden, about 1988 or so.
Ben Wallace got it in 1 985 from the collection at the
Tenom Orchid Center in Sabah and his number
was 85 (the year) and his collection number was
1 981 . Despite all of this collection talk it is a honey
and really flowers for me. Michael Miyashiro is
trying to cross it with several other things that have
the same type of flower".

errors, I forgot to include the one important
sentence in my description of H. meliflua Merrill

to sinus 0.35 cm.; center to apex (flattened) 0.65
cm, making the flower diameter 1 .30 cm.; sinus to
apex 0.40 cm.; with the widest portion of the corolla
lobe 0.35 cm. just outward from the sinus.

Corona: fairly upright, inner apex of lobes
spatulate and upon drying turn outward at a 90$
angle to the central axis, anther apices triangular,
membranaceous extending well above the stylar
head, prominent and visible, outer apex broadly
obtuse; scale saddle sshaped in cross section,

0.035 cm. long, 0.01 7 cm. wide, with long vacuole
adjacent to the sterile edge, this edge extends from
1/2 of the top down the outer edge to one sixth
from the base where it curves under becoming
very narrow. Caudicles are bulbous and
translucent about 0.01 cm. in diameter at pollinia
attachment. Translators are broadly wedge
shaped with a wide flat external edge about 0.01
cm wide; narrowing toward the retinaculum which
is long and somewhat linear, with no definite head,
waist, or hip protrusions. Inner apex narrow and
slightly rounded, outer apex more so with slender
bifid extensions to the stigma and covered with a
clear membrane. Inner apex to outer apex 0.02 cm.
long; inner apex to bifid ends about 0.03 cm. long,
widest portion 0.009 cm.

This new species has been thought to be a
variety or subspecies of Hoya gracilis
Schlechter. The hoya species in the section
Acanthostemma (Bl.) Kloppenburg can be divided
into two broad groups based on the conformation
of the inner coronal lobe. One group including this
new species have a spatulate inner lobe. The lobe
is horizontally much wider than it is thick. Hoya
bilobata Schlechter and Hoya loheri Kloppenburg
also belong in this division. The other more

prevalent form forthe inner lobe has been referred
to as "dentate". Here the inner lobe is laterally
compressed, thus it is thicker than broad
occupying a vertical position in relation to the scale
plane. Hoya gracilis Schlechter, Hoya wayetii
Kloppenburg and Hoya micrantha Hemsiey
among others exhibit this type of inner coronal
lobe. The inner coronal lobes of Hoya gracilis
Schlechter well overlaps (covers up) the anther
appendages at the flower center whereas with this
new species the anther appendages are longer
than the inner coronal lobes and are readily visible
in the flower center.

Another marked difference between the two
species is the shape of the stylar head. In Hoya
gracilis Schlechter it is conic whereas in Hoya
davidcummingii Kloppenburg the apex is
expanded into a bulbous head atop the penta
columnar base. A major difference exists in the
pollinaria of the two species. Hoya gracilis
Schlechter has translators "almost lacking" with
"very small" retinaculum and relatively narrow
finely grained pollinia. The pollinarium of this new
species exhibit distinctive very truncated, short,
wide pollinia, enlarged prominent translator arms
and a relatively long narrow retinaculum. The
pollinarium among other differences set this
species apart from other Philippine hoya species
and all other Section Acanthostemma species.

This species is named in honor of David
Gumming who is an avid plantsman. David has
collected extensively in the Philippines and
elsewhere and has contributed many clones to
living hoya inventories. He is a conservative
collector, taking cuttings only for propagation,
leaving the major portion of wild hoya vines to
continue growth in their native habitat.

Research, Kaaawa, Hawaii (ex clone collected by Ted
Green, TG931 32m Mt Apo, Mindanao, Philippinesat4000’
elevation, on trail to hot springs lake, 30 October, 1993.
Holotype BISH. #7.

Suff rutex, epiphyticus parum ramosus, scandens. Rami
filiformibus, flexuosi, laxe foliati, teretes, glabri. Folia
erecto-patentea vel patula, elliptica oblonga 15-20 cm.

An ornamental climbing vine with leaves similarto Hoya
danA/inii Loher but darker green (almost blackish) in
color; more leathery and of only one type. In addition the
venation of the leaves of this species is perpendicular to
the midrib and finely reticulate, whereas those of Hoya
darwinii Loher are at 45 degrees to the midrib, venation in
neither is prominent. The flower size here is slightly
smaller, the inner is more spatulate than dentate (as is
I Hoya darwinii). The pollinia on this new species has a full
sterile pellucid edge, differing markedly from H. darwinii’s
rather short rudimentary sterile edge. The peduncle bears
approximately 50 buff pink with red centered flowers on
equal pedicels; creating a hemispherical umbel. The sap
is milky white.

Stem: terete, glabrous, 0.4-0. 5 cm. in diameter, green
lenticled, becoming woody-corky; internodes ca. 3-4 cm.
long but varying widely in length.

Leaf blade: 12-15 cm. long x 3-4 cm. wide, narrowly
elliptic, both surfaces glabrous, dull, very dark green,
above slightly channeled along the midrib area, lighter
green below. 10+/- pairs of veins perpendicular to the
midrib, somewhat obscure, with fine secondary reticulate
venation with the base tapered acuminate, outer apex
curved under acuminate, rigid.

Petiole: Lighter green ca. 1.5 cm. long with definite
groove above, otherwise terete.

Pedicel: Straight, terete, 2.7 cm. long x 0.10 cm.
diameter, glabrous with fine granular lenticels, orange
colored.

Calyx: Ciliate (as opposed to H. darwinii Loher) cupped
inward with slightly overlapping sepals, 0.12 cm. long

wides 0.11 cm., apex rounded, with distinct ligules
present.

Ovaries: Somewhat bottle shaped 0.22 cm. tall, rose
apex otherwise pale lemon colored, base of pair 0.1 2 cm.
wide.

Corolla: Sharply reflexed with apex revolute, outside
glossy glabrous, inside with a very fine pubescence, with
long hairs underthe corona around the collar area. Deeply
lobed. Sinus to sinus 0.40 cm., sinus to apex 0.85 cm.,
apex to center 1.15 cm. thus making the flattened flower
2.30 cm. in diameter, widest 0.60 cm. just outward from
the sinus. Collar (tube) 0.05 cm. tall, opening 0.1 5 cm.

Corona: Inner lobe narrowly spatulate touching in the
center, reddish with very fine sulcations, outer lobe much
raised, a very columnar corona. Outer lobe narrow but
thick, fully channeled below, glossy waxy appearance
except for inner lobes. Apex to apex (not flattened) 0.43
cm.; outer apex slightly hooked. Outer apex of anther
wings protrude, anther wing to anther wing 0.23 cm.;
retinaculum to retinaculum 0.1 2 cm.; centerto anther wing
inner apex 0.1 4 cm.; retinaculum outer apex to anther wing
apex 0.12 cm. (anther wing length). Stylar columnar with
head subcapitate, with pentagonal table edges raised
(thickened); fused stigmas distinct above.

Pollinarium: Pollinia 0.074 cm. long rounded apices
with long pellucid sterile edge and extending to outer
curve where attached to caudicle; with a prominent
vacuole. Translators narrow and long 0.1 8 cm. xO.028 cm.,
granular. Caudicle subclear, comma shaped with bulb
0.09 cm. diameter. Retinaculum with distinct inner horns
on a broad head 0.1 5 mm. wide; waist ca. 0.095 mm., 0.1 9
mm. long with 0.07 mm. hip area at attachment of
translators and caudicle 0.09 mm. wide.

Follicle: Linear lanceolate with a truncate outer apex 9
X 0.8 cm. which bear approximately 1 50 seed.

I take great pleasure in naming this hoya species for its
collector Ted Green. Ted has collected extensively over a
long period of time. He is responsible for the introduction
of more hoya species and clones into commerce than any
other single collector. His collecting has been carried out
in the Fiji islands, Vanuatu (when it was called The New
Hebrides), the Solomon islands, Indonesia, Singapore,
Malaysia, Thailand, Borneo and the Philippines. Ted and I
have been personal friends since childhood, a long fruitful
relationship of more than sixty two years.

More About Hoya greenii Kloppenburg

Whether this new hoya is a variety, or subspecies of H.
darwinii or an individual species in its own right has not
been determined. It is however an easy plant to root and
grow. ..at least for me. Since I have been the leading,
number 1 killer of H. darwinii plants and cuttings for the
past eight years, I consider any plant a major find that is a
close relative or near look-alike of H. darwinii, and at the
same time easy to grow.

When I first received this cutting from Ted Green, it was
not too long out of the jungle, or in this case out of the
mountains, as Ted discovered it on Mount Apo in the
Philippines. T ed had not seen any flowers at that time, but
he told me that it struck roots very easily and appeared to
be a good strong grower. Since I had no idea what to
expect in the way of growth or what the flowers would be
like I was very complacent. ..even nonchalant. I stuck it in
my usual rooting mix of 1/2 perlite and 1/2 vermiculite,
placed it on my rooting table that has bottom heat and kept
it barely moist. Had I known that it was a close relative of
H. darwinii, I would have been as nervous as a cat on a hot

tin roof. I didn’t know, however, so perhaps that’s whatf
saved its life. I think we all have a tendency to hover and
maybe pamper to death those plants that have a
reputation for being difficult.

Keep your plant care routine simple with this plant. It is
perfectly happy in ordinary potting soil as long as the
drainage is good. It likes warmth and bright light but has
rather thin leaves so keep it out of direct sun. With proper
care you can expect to see flowers within 1 8 to 24 months
from a small cutting.

Ted was kind enough to send me a picture of this plants
first flowering with a very close-up view of a leaf in the
foreground. My plant is growing, as John Scoville puts it
"like Gangbusters" but I have yet to see any bloom. When
I do, I will get some close up photos of the flowers to share
with you all.

BIRD TRACKS

Robin # 3, January 1995, Dale Kloppenburg, Calif...
Last summer I made cuttings of every plant I had so
will need to pot all of them up along with the new
things that I received last year. A big job. ..but one I
look forward to. I have been seriously thinking about
selling off all my mature plants that have already
bloomed and that I have studied and have photograph
records of. That would cut a lot of my stock so I could
concentrate on the unflowered things and all the new
acquisitions coming along. There are so many new
things being collected that it is almost overwhelming.
After 6 months of work, I finally finished my "Dictionary
of Hoya Terms" and I will never tackle another project
that complex again.

The article on Miguel’s Sperlingia section will be
published in the spring issue of Blumea. In writing the
book on hoya sections I discovered that Miguel had
made a mistake in using Vahl’s Sperlingia, placing it
into synonymy with Blume’s genus Acanthostemma
(that was way back in 1 857). No one had caught the
mistake in all that intervening time. Vahl’s species it
turns out were in the section Hoya. Dr. Veidkamp at
Leiden was able to get the original herbarium sheets
and confirm my findings. The correct name, by priority
for our H. acuta, parasitica, alba etc. now becomes H.
verticillata (Vahl) G. Don.

Ted Green and I were collecting in Sulawesi in
November and December of last year, and collected
many new things. When we found something new we
had to look over every inch of stem to find flowers and
seed pods for study. H. incurvula grew like a weed
down there, some trees were literally smothered by
this species. Most often it was found growing with
Dischidia imbricata and D. nummularia. We found a lot
of H. maxima which may turn out to be the same
species as H. imbricata from the Philippines.

Robin # 3, March 1 995, Bill Crews, Georgia. ..Most
of my hoyas are hanging in there and I know they will
be glad to see me get out into the greenhouse and get
on with my springtime chores. I plan to root fresh
cuttings this spring of all my old baskets and start
them anew. Some of them have not been repotted or
restarted for several years and are looking pretty bad.
When they get so pot bound and the media has
deteriorated I find they don’t do as well for me. Also
some of them are in very large baskets and I want to
go back to the 6" size as they don’t take up so much
space and I can control them better. I’m also going to
reduce the number of different species as I find some
more desireable than others. For instance. ..some with
jungle growth and no blooms are on their way out.

Others that I really enjoy like H. lacunosa which I’ve
lost, will be replaced. It’s about time for the aphids and
mealies to return so that battle will begin anew.

I’m sure most of you have heard about the new
organic pesticide being produced from the seed of the
Neem tree (India). It came out in recent years and was
quite expensive. I found a product called BioNeem
which must have been somewhat reasonably priced or
I wouldn’t have a bottle of my own. It’s not effective on
adult insects but it acts to interrupt the molting
process in the development of the insect. I will be
using a lot of that this year to see if it will help my
insect problems.

Robin # 5, November 1994, Carita
Forsberg-Heikkila, Porvoo, Finland. ..Do you know
much about Finland? Maybe I will tell you a bit about
it, if you don’t mind. First the weather. I envied
Harriette when she wrote "today it is a lovely warm day
(75 degrees F.) Here in Finland today we have -3
degrees C. It’s drizzly, cold, snowing and raining at
the same time, and it’s dark almost all day long. In
other words it’s winter. This season starts in
October/November and ends in March. I agree with
John, this cold climate and long winter months are
really miserable. John wished that all our robins could
be in Hawaii. ..So do I! but when the summer comes,
you can enjoy the sunlight all night long, especially in
Northern Finland. And it is sometimes even warm,
over +30 degrees C. ..about 54 degrees fahrenheit.

Well let me now tell you how I became interested in
hoyas. Everything started about 1 8 years ago when I
got my first H. bella from my aunt. It became bigger

14

and bigger and flowered eagerly every year. 1 liked it
very much and had it almost 10 years before it died.
Now my oldest hoya, H. carnosa is 15 years old, and
with it 1 have learned something about hoyas. I have
always like H. carnosa because it is so easy to grow
and its flowers are so beautiful. However, the first time
I saw pictures of H. macgillivrayi and H. imperialis I
lost my heart to hoyas (that happened in 1 987). I just
wanted to have different hoyas, but when I asked the
Finish nurseries if they had Hoya imperialis they just
looked at me and said "Hoya what???? Sorry we don’t
have it and we’re not going to get it because it costs
more than 20 Fmk.. .nobody here wants to pay so
much for a plant. It took me over 7 years to get one
and now I think I may be the only hoya lover in Finland.

Last spring I bought 1 5 different hoyas from
Liddle’s Nursery and now i have pots of plants in every
room. I don’t have a greenhouse so my hoyas are in
my living room. All cuttings are alive and most of them
are growing.

Robin # 5, November 1994, Maria Blom,

Sweden. ..My passion is plants (both indoor and
outdoor kinds). Then there are a lot of potted plants
indoors and those that require low temperatures
during winter live in our garage. In order to get more
space in the house, my husband built me some light
stands, where I grow a few gesneriads and hoyas as
well but I am not sure that the hoyas get enough light
there. Have any of you had experience growing under
fluorescent light? If so how, how much fertilizer do
they require? The ones I have growing in the
windowsill get fertilized very seldom, just a couple of
times in the spring as they are dormant for such a long
time.

Do you know where Sweden is situated? If you look
at a globe of the world you will find it at the same
latitude as Alaska and the Southern parts of
Greenland. It is not as cold here as it is in
Alaska. ..Thanks to the gulf stream, but the light, or

rather the absence of light during the winter is the
same. If I don’t consider my plants, I actually like the
winter. I like the cold, crisp air and find the twilight
quite cozy.

Hoyas are my absolute favorites, but I have not
grown them for such a long time. My first hoya was a
carnosa which seems to have been around forever.. .it
tolerates anything. My second hoya, H. bella is also
old and quite big by now but a lot fuzzier. Mine likes it
when it gets hot indoors. My third one was H. linearis
which I started from a small cutting that I got at a
botanical garden. I thought I had never seen such a
weird looking plant before. Now it is my favorite and
although the flowers are not spectacular the fragrance
is wonderful. Recently it bloomed from 20 spurs.

Five years ago I read an article about a woman who
had almost 1 00 different hoyas. I never knew there
were so many of them. I wrote to her (Berit Carigren)
and that is how it all started. 1 got a few cuttings from
her, an H. nicholsoniae among others that has grown
big but has not bloomed and another one called H.
siamica. It looks a bit like H. longifolia with fragranced,
hairy white flowers with a touch of carmine under the
corolla, but the leaves are thinner.

Three years ago I got in touch with Eva-Karin
Wiberg who has now started a Swedish Hoya Society.
She has taught me a lot and has given me cuttings
from many hoya species. Now I have about 150
different species and cultivars. Some of them look the
same although they have different names, but then the
confusion seems to be big in the world of hoyas. Many
of them are small yet and it will probably be awhile
before all of them bloom, if they ever do. But if I look at
the leaves my favorites are the tiny H. engleriana, H.
caudata and H. thomsonii, and then magnifica of
course which is in bloom now. I find the flowers very
beautiful but the odor is too heavy for my liking.

What can one possibly say about a flower this
beautiful that we know nothing about?

All I know for sure, is that it is a hoya in the
Eriostemma section. It grows very well if some extra
lime is added to the potting medium and it likes warm
temperatures and bright light. I believe Ted told me

that he collected it in the Philippines in 1 993, but
please don’t hold me to that statement.. .I’ve been
known to get my tang tongueled up, then Ted has to |
correct me. The cutting that I have of this plant came j
to me with Ted’s Number 94027 in case anyone would i
like to order one for their own collection.
