- Asplenium ×rouyi, the hybrid of A. onopteris
and A. scolopendrium, previously found only once, more than 100
years ago in continental Portugal, was rediscovered on Faial Island,
Azores, in 1999. Its morphology, cytology and ecology are described for
the first time.

- Continuing a series of miscellaneous contributions, by various
authors, where hitherto unpublished data relevant to the Med-Checklist
project are presented, this instalment deals with the families Isoetaceae;
Amaranthaceae, Asclepiadaceae, Boraginaceae, Caryophyllaceae, Cistaceae,
Compositae, Cruciferae, Labiatae, Leguminosae, Lythraceae, Onagraceae,
Polygonaceae, Rafflesiaceae, Rosaceae, Salicaceae, Sapindaceae,
Solanaceae, Umbelliferae, Violaceae; Cyperaceae, Gramineae,
Hydrocharitaceae, and Juncaceae. It includes new country and
area records, taxonomic and distributional considerations. A new species
of Halimium is described and illustrated. New names and
combinations are validated in Amelanchier and Lonicera.

- Ranunculus (sect. Ranunculastrum) veronicae, showing
some similarities with R. subhomophyllus, is described as new to
science and illustrated. The early flowering species is known only from
a single population in the westernmost part of the island of Crete,
where it grows at low altitude on schistose rock under Platanus
orientalis trees.

- The continuation of studies on Phragmites frutescens in Crete
revealed its taxonomic distinctness and fairly wide distribution in
Crete as well as in Greece in general. A revised morphological
description and differentiation against P. australis and P.
mauritianus are presented. As a result, the synonymisation of this
tall, woody, branched, winter-flowering reed with P. australis
is rejected. Its preferred habitats are described as being near
permanent water. It is considered to have evolved in isolation from the
tropical P. mauritianus after post-glacial desertification of
northern Africa. By now most stands of P. frutescens have been
heavily devastated by anthropogenic action.

heterophyllum L'Hér. (Lamiaceae) with two new
subspecies of the Canary Islands. – Willdenowia 30: 263-271. 2000. –
ISSN 0511-9618.
- Teucrium heterophyllum, a species originally described from
Madeira and also distributed in the Canary Islands, is subdivided into
three subspecies on the basis of differences in the calyx length, in the
size of the branched, non-glandular trichomes on calyx and leaves, and
in their distribution areas. From the Canary Islands T.
heterophyllum subsp. hierrense, endemic to El Hierro, and
subsp. brevipilosum, endemic to Gran Canaria, Tenerife, La
Gomera (?) and La Palma, are described as new to science. A key to and a
distribution map of the three subspecies are provided.

affinis from SE Egypt and NW Sudan and S. fallax from the
Nanga Parbat region, N Pakistan, are described as new to science. The
first record of Stipagrostis libyca from Sudan refers to a new
subspecies, S. libyca subsp. darfurensis.

ISSN 0511-9618.
- Arabis (sect. Drabopsis) lycia is described
as a species new to science and illustrated, and its taxonomic position
close to A. bryoides of the S Balkans is discussed. SEM
micrographs of the indumentum of A. lycia and its relatives (A.
bryoides, A. carduchorum, A. drabiformis) are presented and their
ecological requirements outlined. The new species is a subalpine
cushion-forming plant of shaded vertical limestone rocks along the ridge
of the Bakirli Dagi in the eastern part of the Western Taurus in Turkey.
The chasmophytic habit and its stenochory suggests that A. lycia
should be included in the list of relic endemics known from the
mountains W of the Bay of Antalya.

2000. – ISSN 0511-9618.
- The genera and species of the subtribe Hypochaeridinae
occurring in the Arabian Peninsula are studied and data on their
taxonomy and distribution given. Six genera have been recorded. Picris
is represented by four species, i.e. P. babylonica, P. cyanocarpa,
P. longirostris and P. scabra (with two subspecies), the
other genera are represented by one species each, i.e. Hedypnois
cretica, Hypochaeris glabra, Leontodon laciniatus, Rhagadiolus stellatus
and Urospermum picroides. The subtribe is absent from the
Socotra archipelago. The new combination Picris scabra subsp.
abyssinica is validated and a neotype designated for P.
scabra. Chromosome counts are reported for Yemeni origins of Picris
scabra subsp. abyssinica (2n = 10), subsp. scabra
(2n = 10, first report) and Urospermum picroides (2n = 10).

- The chromosome numbers of 31 taxa belonging to 14 families of
angiosperms collected from different regions of Saudi Arabia are
reported. These include first chromosome number reports for six species:
Anabasis setifera 2n=18, Cleome amblyocarpa 2n=20, Halopeplis

laevicaule Bornm., a synonym of Erysimum crassicaule (Boiss.)
Boiss. (Brassicaceae). – Willdenowia 30: 359-360. 2000. –
ISSN 0511-9618.
- Sterigmostemum laevicaule, described by Bornmüller in
1910, has been a nomen dubium since the single specimen ever known was
destroyed in Berlin-Dahlem in 1943. A search in the type locality
produced evidence that the description actually refers to Erysimum
crassicaule, a name that has priority. A corresponding neotype is
designated for S. laevicaule.

flora of China, with critical notes on Tordyliopsis DC. and Keraymonia
Farille. – Willdenowia 30: 361-367. 2000. – ISSN 0511-9618.
- Two genera of the Umbelliferae, Tordyliopsis and
Keraymonia, previously not known from China, have been revealed on
the basis of original collections made by German-Chinese expeditions to
Xizang (Tibet) Autonomous Region and adjacent areas. Tordyliopsis
brunonis, gathered on the Tibetan side of the Mt Everest massif, was
known only from India and Nepal. The mature fruit of Tordylopsis
is described from Nepalese material. Keraymonia cortiformis, found in
the Tibetan part of Mt Xixabangma, belongs to a genus with its
previously known distribution limited to the Nepalese Himalaya. Findings
of two additional species from other genera, Chamaesium mallaeanum,
from Xizang (Xixabangma), and Aulacospermum stylosum from
Xinjiang (Karakorum, K2 North slope), are also new to the Chinese flora.
- Dressler, S.: A new species of Marcgravia
(Marcgraviaceae) from Amazonia with some notes on the Galeatae
group including a key. – Willdenowia 30: 369-374. 2000. – ISSN
0511-9618.
- Marcgravia zonopunctata is described as a species new to
science and illustrated. The species is remarkable for its hypophyllous
glands arranged in bands on the lower leaf surface (not known before
from Marcgravia), for its peculiar shape of the nectary bracts
and for its inflorescences appearing on short-shoots (as far known).
This is the first species of an unranked, obviously natural group within
Marcgravia (Galeatae group) known to range in Amazonia
and at low altitudes. Some features of this Galeatae group are discussed
here (e.g. pollination, distribution, leaf anatomy) and a key to its
species is given.
