- A synonymic survey of Anthemideae genera accepted for the
purpose of the Euro+Med Project is presented. As a consequence of
nomenclatural revision, shifts in generic circumscription or
reassessment of accepted specific and subspecific taxa, combinations
that are required in the genera Achillea, Anthemis, Artemisia,
Cota, Leucanthemum, Mecomischus, Phalacrocarpum, Rhodanthemum and
Tanacetum, but do not so far exist, are validated. A North
African species hitherto lacking a valid name is described anew as
Plagius maghrebinus.

- A synonymic survey of Astereae genera accepted for the
purpose of the Euro+Med Project is presented. As a consequence of
shifts in generic circumscription, or reassessment of accepted
specific and subspecific taxa, combinations that are required in the
genera Erigeron, Eurybia, Galatella, Symphyotrichum and
Tripolium, but do not so far exist, are validated. In one case
(Erigeron alpinus subsp. intermedius) the validity
of a previous combination, even though it was rather irregularly
proposed, is confirmed.

-
Lemnos island and its 10 offshore islets belong to the Prefecture
of Lesvos and biogeographically to the N Aegean area. In comparison
with other islands of the N Aegean area, Lemnos is characterized by
an intense horizontal relief, absence of limestone cliffs, low land
formations (highest point 429 m), medium inclination and intense
human interference (agriculture, stock farming) almost on the entire
island. Including the data from the available literature and the
authors' investigations, the flora of the area consists of about 681
plant taxa. The dominance of the Mediterranean elements and
therophytes reflect the Mediterranean character of the Lemnos flora.
Although its flora is rather poor, Lemnos conserves a high level
ecological value based on the existence of a variety of different
vegetation formations and habitat types such as wetlands, sand
dunes, remnants of Quercus ithaburensis subsp.
macrolepis forest and extended phryganic formations all over the
island. The natural ecosystems (wetlands, sand dunes, etc.) have
been degraded because of the intense human activities (extended
agriculture, over-grazing, tourist facilities, etc.) and for this
reason the adaptation of management measures is necessary for the
conservation of the ecological value of the area.

- Cousinia gatchsaranica from the southwestern Zagros Mts
is described as a new species and illustrated. It can be assigned to
the hitherto dispecific C. sect. Haussknechtianae
and shows closer affinities to C. raphiocephala. The
taxonomic position of C. raphiocephala is confirmed on the
basis of fruiting material, the description of C. sect. Haussknechtianae
is emended and a key to the species of the section provided.

- A stand of Pterocarya fraxinifolia, hitherto unknown to
science, is reported from the central Zagros mountains in the
Irano-Turanian part of Iran, at an altitude of 1730 m, far disjunct
from the populations at the Caspian Sea and in the Van area in SE
Turkey. It has long been protected by the local people, who believe
that cutting these trees is inauspicious. Structure, size and
phytogeographical importance of the stand is discussed and its
protection, along with nearby gigantic Platanus orientalis, as a
national natural monument suggested.

on some Sino-Himalayan species of Angelica and Ostericum
(Umbelliferae). – Willdenowia 33: 121-137. –

- Based on own field observations and collections as well as on
material from various herbaria, Sino-Himalayan species of Angelica
and Ostericum were studied, emphasizing fruit anatomy. A.
indica from NW Himalaya, Uttar Pradesh, a species allied to A.
glauca, is described as new to science. Three combinations, Ostericum
longipedicellatum and O. muliense, for two species here
transferred to that genus, and Heracleum oncosepalum, for a
species excluded from Angelica, are validated. The known
distribution range of the Himalayan A. nubigena is extended
to SE Tibet, and, inferred from fruit anatomy, the species is shown
to be closely allied to A. cyclocarpa. Reconsideration and
comparison of Chinese Angelica species described by European
botanists prior to the mid 1930s and by Chinese botanists in the
1960s finally led to the recognition of new synonyms of A.
duclouxii, A. laxifoliata, A. nitida and A. wilsonii.

- Suaeda tschujensis is described as a species new to
science and compared with related species of S. sect. Brezia
(= Heterosperma). It is endemic to high-mountain semideserts in
the Russian Altai and to the Gobi Altai in Mongolia. The species is
of particular interest for the phylogeny of the genus because of its
rare diploid chromosome number of 2n = 18.

Three new species of Selaginella (Selaginellaceae) from Cuba. –
Willdenowia 33: 159-166. – ISSN 0511-9618; © 2003 BGBM
Berlin-Dahlem.
- The three new species are narrow-range endemics: Selaginella
caluffii is restricted to Topes de Collantes and its
surroundings (Alturas de Trinidad, central Cuba), S. ivanii
is only known from Pico San Juan (same area) and S. achotalensis
occurs on the Mogotes de Yambeque and their neighbourhood (Monte
Rus, Guantánamo province, eastern Cuba). All are described
and illustrated. The two central Cuban species are the second and
third known Cuban representatives of the articulate selaginellas,
S. subg. Stachygynandrum.

- Recently, an endemic insectivorous species new to science,
belonging to Pinguicula sect. Agnata, has been
detected in the Cajálbana region not far from La Palma, Pinar
del Río Province, Cuba occidental, in the immediate
neighbourhood of P. albida. The new species is named P.
cubensis, described and illustrated.

with Ardisia mogotensis (another western Cuban endemic),
Myrsine pipolyi from Topes de Collantes (central Cuba, prov.
Sancti Spíritus) and Myrsine bissei from the Moa area
(eastern Cuba, prov. Holguín). The flora of Cuba now includes
seven species of Ardisia and six (one previously unrecorded)
of Myrsine.

(Erythroxylaceae) of the Greater Antilles. – Willdenowia

- Three new Antillean species of Erythroxylum are
described: E. mogotense and E. banaoense from Cuba
and E. domingense from Hispaniola. The main diagnostic
characters are leaf morphology, stipules and number of flowers per
axil. Phenology, ecology and chorology are also relevant criteria.
E. williamsii, described from Venezuela, is a new record for
Hispaniola.

ISSN 0511-9618; © 2003 BGBM Berlin-Dahlem.
- Two new species of Miconieae (Melastomataceae) from cloud
forest refuges of the Coastal Cordillera of Venezuela are described
as new to science. Clidemia intonsa grows in Cerro Patao in
northeastern Venezuela and is most similar to some species from
Trinidad. Miconia chapensis grows in Cerro La Chapa at the
western extreme of the Coastal Cordillera and resembles one species
from French Guiana and Surinam and two species from Central America
and the west coast of northern South America.

ISSN 0511-9618; © 2003 BGBM Berlin-Dahlem.
- Based on a recent bryophyte collection from the hitherto
botanically neglected Al-Mahra Governorate in Yemen, the rare
neotropical Erpodium glaziovii (Erpodiaceae) as well as Cololejeunea
minutissima subsp. minutissima and the pantropical Lopholejeunea
nigricans (Lejeuneaceae) are reported for the first time from
the Arabian Peninsula. They are an important element of the
epiphytic bryophyte flora in the monsoon-affected, endemic S Arabian
Anogeissus dhofarica woodland and confirm the repeatedly
demonstrated xerotropical character of this part of the Arabian
Peninsula.
