Distribution. About 50 with about 500 in genera species, chiefly developed south and tropical and ; it is almost cosmopolitan.

to In addition subfam. Gonystyloideae which contains 3 genera with 21 species and has been treated in

this Flora (I, 4, 1953, 349-365) by AIRY SHAW, there are 9 genera with 46 species in Malaysia.

Gyrinops, Enkleia and Linostoma are confined to Malaysia and the southern of Aquilaria, , part tropical

continental SE. Asia. is widely distributed, from eastern Asia at about 37° N southward

throughout Malaysia to northern and eastern Australia and the Pacific Islands (Bonin, Guam, Palau,

Hawaii, Tahiti, Marquesas, Tonga, Samoa, Fiji, Norfolk I., and New Caledonia).

Daphne is distributed in Europe, northern Africa, through central Asia, eastward to China and Japan,

and southward to Malaysia.

Phaleria is developed chiefly in Malaysia and Fiji, westward to Ceylon (P. capitata), southward to

eastern Australia, and eastward as far as Palau, Samoa, and Tonga.

Drapetes shows the typical pattern of S. Pacific subantarctic distribution: South America (Fuegia and Falkland Is.), New Zealand, Tasmania, SE. Australia, and Malaysia (New Guinea and Borneo).

Pimelea is chiefly confined to Australia, with some outlying species in New Zealand, and two others

extending northward to Malaysia (Timor, Sumba, New Guinea, and Luzon in the Philippines).

Ecology. Most Malaysian species are of small to moderate size, while a few species of Aquilaria,

and 45 tall. but , Gonystyloideae are trees up to m They usually occur scattered, Gonystylus

bancanus sometimes stands. constituents of may occur gregarious, forming pure They are chiefly primary

and secondary rain-forests, while occurs predominantly in freshwater swamp and found peat forest; recently J. A. R. ANDERSON Linostoma longiflorum in peat swamp forest in Sarawak.

Most of the species occur at low and medium altitudes, some of them ascending into the montane zone

(e.g. capitata 0-1200 m and Linostoma pauciflorum 0-1300 m), or evenconfined to the montane

zone (e.g. composita commonly recorded from 1200-2000 m, and Aquilaria apiculata from

1800 m). A few are restricted to the upper montane and subalpine rain-forest (e.g. Daphne luzonica

2000-2500 m, and Wikstroemia brachyantha 1400-2800 m). Drapetes ericoides is commonly reported

from the subalpine to alpine zone from 3000-4450 m.

As to climate, most of the species are confined to everwet regions, some also extend to seasonal areas

(e.g. Phaleria capitata, Gyrinops versteegii, and ), while Wikstroemia androsaemifolia

and Phaleria octandra chiefly occur under seasonal climatic conditions.

Pollination. Insect-pollination is indicated by the brightly coloured, generally many-flowered

the the of floral and the usual of the inflorescences, sweet scent, occurrence heteromorphism, presence

hypogynous disk (fide RENDLE, Classif. Fl. PI. 2, 1952, 371). I have no records of observations on Malay-

sian species.

Dispersal. Though no direct evidence has been recorded from Malaysia it can be indirectly inferred

that the red or black coloured drupaceousfruits of Wikstroemia, Phaleria, and Daphne will be dispersed

endozoically by birds or other animals. See RIDLEY, Disp. (1930) 401, 466, 472, and GUPPY, Observ.

Nat. Pac. 2 (1906) 348. Wikstroemia indica has, probably through this agent spread from the Botanic

Gardens at Bogor but its area is only slowly, though steadily, extending into a circle with Bogor in its focus; its radius of c. 60 km was reached only after several decades.

Another dispersal class is represented by species of Linostoma and Enkleia. In Linostoma the in- florescences consist of a few inconspicuous flowers subtended by a pair of thin, cream-coloured or

show attractive rose-pink coloured leaf-like bracts. In anthesis they possibly act as a apparatus to

fruit is ripe, and are to fruit, pollinators. They become pale and papery when the detached,adhering the the of bracts below the inflorescence so as to be blown away separately. In Enkleia, a lofty climber, pair is very inconspicuous during anthesis, but in fruit (one developing only) the peduncle below the small

Though structure most peculiar, its effect (for longer distances) must not be overrated as winds are scarce in the tropical rain- forest, the apparatus is rather heavy, and as soon as it descends in the canopy it will come down, gradu- ally, in a vertical line.

A third, very interesting dispersal class is represented by the capsular fruits of Aquilaria and Gyrinops, in which the seeds dangle from the apex of the fruit valves onfiliform funicles, the glossy seeds having typically contrasting dark colours and possessing tails or other aril-like structures, probably of a pale

structure is doubtless curious colour, as is also found in Gonystyloideae (fig. 1 and 22). This a adaptation to zoochorous dispersal, but unfortunately no observations have as yet revealed more exact data on its functioning.

Galls. DOCTERS VAN LEEUWEN (Zoocec. N.I. 1926, 397, f.735) recorded a leaf-gall caused by a gall- midge in Phaleria laurifolia (= P. octandra). The leaves bear spherical galls, 2-3 mm in diam. of Heteromorphous flowers. The flowers are heteromorphous in . Two kinds

stamens and a flowers are commonly found on different of that species, viz possessing exserted short style and short stamens and an exserted style.

Therefore, the tube is not an invaginated (fide LEANDRI, Ann. Sc. Nat. °t. X, 12, 1930, 235). Miss HEINIG (Am. J.

Generic delimitation in sometimes be difficult of the fact that Thymelaeaceae proves to very on account

though the majority of the species of one might be distinguished from those of another genus by

two or even more good characters, there are frequently one or two species - or even different specimens

of one species - which form an exception and are transitional in all but one character. Consequently

is such genera are then sharply separated by one character only, which an unsatisfactory situation.

For instance in Phaleria the petaloid appendages are rim-like, but they are distinct in P. pentecostalis

LEANDRI. In Aquilaria the opposed case occurs, viz that they are distinct in all species except in A.

urdanetensis where they are rim-like. In Aquilaria the anthers are always free from the tube except in where adnate the in of the Also in the A. cumingiana they are partly to tube part specimens! Aquilaria

petaloid appendages are free except in part ofthe specimens of A. cumingiana; the same phenomenon is

observed in Gyrinops where they are free, but in G. moluccana and G. decipiens they are usually united.

Dr B. PETERSON, Lund, who is working on the African Thymelaeaceae, told us of similar difficulties

wrote encountered in defining genera in that area. He (May 1959): "I have devoted much time to generic

delimitation in this family. As I have examined more and more African material (c. 15.000 sheets)

limits in unavoidable several 1 have found that the are some cases so vague that it has appeared to merge

genera. It is often rather easy to give a specific epithet but very difficult to come to a decision of the

generic name. For example the only generic characters in Gnidia, Lasiosiphon, and Arthrosolen, and some

smaller genera, are the number of calyx lobes and the presence or absence of petaloid appendages. And Sometimes these these are not at all enough to keep these genera separate. characters do not even hold

for the GILG and later STANER that these should be united but other type species. proposed genera

botanists have not followed their suggestions. In my monograph of Gnidia 1 will merge seven genera."

and be the first the second Aquilaria Gyrinops seem to very closely allied, being diplostemonous,

haplostemonous, which is the only constant character. HALLIER /. found this difference not sufficient

for generic distinction and united these genera. Dr PETERSON found in Africa a similar case, viz between

Gnidia and of which the first is diplostemonous, the second haplostemonous. He "never

found any trace ofstaminodes in Struthiola. In some species of Gnidia, however, usually, but not always,

the upper whorl of stamens is abortive. All species of Struthiola have a whorl of hair round each petaloid

appendage. This arrangement is not found in Gnidia except for a single species as far as I have found.

This will be placed in a separate section."

In Dr PETERSON'S opinion Struthiola and Gnidia, though properly only distinguished 'absolutely' by

should if that the would that one character, not be united; were done, consequence be still more genera

had to be merged in the complex which would lead to an unsatisfactory situation. In this revision I have not followed HALLIER /. in uniting Aquilaria and Gyrinops.

The difference between Wikstroemia and Daphne seems, by being merely vegetative, still more feeble,

the chief distinction being the opposite phyllotaxis in Wikstroemia, notwithstandingthe note by STAFF

(Bot. Mag. 156, 1933, sab t. 9313, p. 2). If it is realized that the phyllotaxis varies widely within the single

genus Pimelea, it is tempting to merge Wikstroemia and Daphne.

The merging of Aquilaria and Gyrinops and of Daphne and Wikstroemia might give a better reflection

of natural the character the of these in the affinities, as single separating components pairs effects, my

opinion, not a natural segregation.

Specific delimitation in Thymelaeaceae is in many cases also extremely difficult, specially because it

not also within flowers of has appeared that characters only vary within a single species, but the one

single specimen, as for example the shape of the disk in Wikstroemia aurantiaca (cf. STAPF, I.e.). I have

encountered several similar cases in other species and Dr PETERSON communicated to have a similar

to experience with African representatives which has led him a severe reduction of accepted species.

difficult in Wikstroemia and Phaleria for Specific delimitation in Malaysia proved particularly ;

much wider limits than W. indica I have accepted specific my predecessors.

laeaceae and other families, one should consult the works of DOMKE (Bibl. Bot. Ill, 1934, 1-3, 16) and

HEINIG (Am. J. Bot. 38, 1951, 113 & 131).

In the Kew Herb, there are two specimens of

cultivated origin identified as Phaleria laurifolia.

One ofthem has flowers with a floral tube glabrous

outside which has been used for the plate in CURTIS'S Bot. Mag. t. 5787; the other has flowers

with a floral tube pubescent outside. In other res-

pects their characters entirely agree. It is not clear

whether they were collected from the same or from different plants.

According to VALETON (IC. Bog. 4, 1913, 47)

P. octandra is slightly more xerophytic than the

others and obviously cannot well maintain itself in rain-forest and the specimens which had been

introduced in the Bogor Botanic Gardens have

Note. Some specimens collected at Davao

and MERRILL 11616) seem to be a distinct local

form of P. perrottetiana; this form differs from

the typical one only by the rather small flowers

(c. 2 cm long) and the floral tube which is glabrous

outside. Because of the of kinds of presence two flowers P. perrottetiana has been placed in the key twice.

Some specimens (v/z CARR 11353, 11672, and

HOOGLAND 3788) bear large fruits (c. 3 by 1% cm) with rather thick pericarps (c. 2 mm). Their

enormous size might have been caused by the

attack of insects, as there are always hole(s) on the pericarps and excrements of insects inside the

fruits.

BENTHAM (I.e. 36) and GILG (Bot. Jahrb. 18, 1894, 514, f. 9A). I have also observed this variation in a

single specimen (TRAVERS s.n., IV, 1909, New Zealand), and even in a single flower! Because of the of great resemblance in habit and the number stamens being the same as that of the perianth lobes,

BENTHAM (I.e. 36) and BENTHAM & HOOKER/. (Gen. PI. 3, 1880, 196) reduced Kelleria and Daphnobryon

to Drapetes. I have followed them in this treatment and believe the first and last could be distinguished
