16 NOTES ON THE ACANTHACEAE OF JAVA
Habitat Javam Orientalem.
East Java. Surabaja Res.: Surabaja, DORGELO 602 et 1962 L; Malang Res.:
Redjoso near Pasuruan, BACKER 36417 L, typus var.
As VAHL'S ,type needs a name to distinguish it fromthe two varieties
described above, I will call it Nomaphila stricta (Vahl) Nees var. vahliana
Brem. n. nom.
34. BriUantaisia Pal. Beauv.
A representative of this West-African genus has maintained itself for
many years in the neighbourhood of Buitenzorg, wh ere is was collected
for the first time in 1888 by BOERLAGE(d. BACKER in Ann. Jard. Bot.
Buitenz. Suppl. lIl, p. 396, 1910). BOERLAGE identified it as Br. owariensis
Pal. Beauv., but a reinvestigation of the specimens has shown that they
belong to another species: the leaves are too wide for Br. owariensis and
moreover on both sides hairy instead of glabrous. 1 bring them to Br.
leonensis Burki11. This species and Br. lamium Benth. have long been in
cultivation, whereas the other on es, inc1uding Br. owariensis, are outside
the country of origin apparently known from herbarium specimens only.
Br. leonensis and Br. lamium were both figured under the name Br. owariensis
on tab. 4717 of the "Botanical Magazine", which probably accounts
for BOERLAGE's misidentification.
36. Lepidagathis Willd.
In BOERLAGE's "Handleiding" (11, 2, p. 660, 1899) the following Lepidagathis
species are mentioned as indigenous in Java: L. straminea Miq., L.
parviflora BI., L. javanica BI., L. billardieriana Nees, L. setigera BI., L.
incana (BI.) Nees and L. repanda BI., and as L. hyalina Nees is said to
occur in "Nederlandsch Indië", Dy which BOERLAGE probably means that
it is found throughout the Dutch East Indies, the latter's name may be
added to th is list. Several of these names, however, will have to be expunged,
either because they do not occur in Java or because they belong
to other genera. L. incana and L. repanda fall in the second category, for
L. incana (BI.) N ees (Adenosma BI.) is Staurogyne incana (BI.) O.Ktze,
an,d L. repanda BI. is Adenacanthus repandus (BI.) Brem. L. setigera BI. is,
as I have shown elsewhere (in Verh. Ned. Akad. v. Wet., Afd. Natuurk.,
2e Sect. Vol. XLI, p. 95, 1944), to be regarded as a "nomen confusum".
for the description has been based partlyon a shoot of Hemigraphis serpens
(Nees) Boerl. ex Backer and partlyon a shoot of a Lepidagathis
spedes, probably L. javanica BI. var. brevispica Brem. v. infra. L. straminea
Miq. was based on a specimen grown in the Buitenzorg Botanie Garden.
The origin of this specimen was unknown. MIQUEL ,thought that it
might be a Javan plant, but this is probably amistake, for our herbaria
possess no specimens that have been found here. Some specimens col-
