THE IDENTITY OF HORNERA Jungh. (Thymeleaceae)

A. J. G. H. KOSTERMANS *)

Dr. Airy Shaw (Van Steenis, Fl. Males. Ser. I, 6(1): 48. 1960), referred
Hornera Jungh. (Tijdschr. natuurl. Geschied. & Physiol. 7: 314. 1840) ten-
tatively to Lauraceae.

Hornera was described in an article with the misleading title: Nova
genera et species plantarum Javanicum, as the species numbered 22 to 27
are from Japan. Under no. 22 there is a remark: "siccatam e regius japonico
accepi".

Flora Malesiana gives no clue where this Japanese collection came from;
no collecting localities and no collectors are mentioned by Junghuhn **).

According to Maximowicz (in Bentham & Hooker f., Gen. PI. 3: 188—
189. 1880) the genus should not be Japanese; this wrong statement is
apparently due to the fact, that Maximowicz could not attribute the genus
in its circumscription to any Japanese plant.

Hornera Junghuhn, according to the author related to Gnidia, is des-
cribed with two species. As the type specimens so far have not been located,
identification has to be based entirely on the descriptions, which are, lucki-
ly, very extensive.

Hornera umbellata (I.e. 314) represents without doubt a species of
Neolitsea Merr. The flowers are dimerous and the flower described is a
female one. The stalked glands were mistaken by Junghuhn for stamens.
There are 6 "fila sterilia". which represent the 6 sterile stames, which in
Neolitsea are arranged in 3 cycles of 2 opposite stamens each. The descrip-
tion fits Neolitsea perfectly and the lengthy and adequate description will
make it possible to identify even the species, when Neolitsea of Japan is
revised.

The second species: Hornera glomerata (I.e. 316) belongs either in
Litsea, Lindera or Actinodaphne. As nothing is stated about the leaves
being verticillate, me may exclude Actinodaphne. As Lindera has usually
triplinerved leaves, the best guess is Litsea.

*s;) Perhaps Junghuhn received his material from H. Burger (cf. Van Steenis -
Kruseman in Blumea 11: 495. 1962).

Again a female specimen is described having 6 stalked glands, wrongly
described as the stamens and 9 sterile stamens ("9 fila"), which fits Litsea
perfectly. Here too, the description of the vegetative parts leaves little
doubt, that Litsea is meant.

Consequently Hornera represents a mixture of Neolitsea Merr. (1906)
and Litsea Lam. (1791) and may be discarded already for that reason.
Moreover Neolitsea and Litsea are both nomina conservanda.

The specific names, however, might have priority over current names.

THE OLDEST SCIENTIFIC NAME FOR THE CINNAMON TREE

Cinnamomum zeylanicum BL, 1826, has been currently considered to
be the proper name for the common cinnamon tree. This name was already
in use during the pre-Linnean period (cf. Kostermans, Bibliogr. Laur. 364.
1964).

The oldest valid name, however, is Cinnamomum verum J.S. Presl,
1825, This is not a pharmaceutical name, as is evident from the references
cited by Presl and by the treatment of other species. For complete refe-
rences cf. Kostermans, Bibl. Laur. 360, 1964.

LAURUS CAESIA RWDT. EX BLUME, the oldest name
for Acer laurinum Hassk. (Acer niveum Bl.)

The oldest description of this tree, common in western Malesia, is
Laurus caesia Rwdt. ex Blume (Bijdr. Fl. N.I. 553. 1826). The description
was based on a specimen, collected by Reinwardt, apparently in W. Java,
as Blume cites the Sundanese name: Huru (= Lauraceae) madum (perhaps
a misspelling of madu = honey).

Blume cited this specimen already in 1823 in his Catalogue. Duplicates
of the type specimen, which are sterile, may be found in numerous her-
baria (Kopenhagen, Leiden, Leningrad, etc.).

This is the plant alluded to by Junghuhn in his Travels (Reizen) in
Java, where he remarked, that Blume was not able to distinguish an Acer
from a Laurus!

Nees, 1836, referred the specimen (with a question mark) to Daphni-
dium (cf. Kostermans, Bibliogr. Laur. 578, no. 5a. 1964).

Villar, 1880, on the authority of Nees, referred the species to Lindera
(cf. Kostermans, I.e. 744).

155—169. 1962.
