Two new aroids from South America. - Willdenowia 32: 323-329.

- Two new species of Araceae from South America are
described and illustrated. The one is Anthurium ensifolium
from Bahia, eastern Brazil, which is tentatively placed in A.
sect. Urospadix subsect. Obscureviridia. It seems
close to A. cleistanthum, a poorly known species from Espírito
Santo, Brazil, and also resembles A. erskinei from Bahia.
The other is Gorgonidium bulbostylum from Andean Bolivia,
which differs from all other species of the genus by the unusual
aspect of the style that has an inflated, more or less ovoid apical
portion. The stigma is also peculiar in being globose and
conspicuously lobed, with lobes upwardly directed.

novelties in the genus Alsophila (Cyatheaceae). -
Willdenowia 32: 303-309. 2002. - ISSN 0511-9618.
- Three new interspecific hybrids of Alsophila have been detected
in Cuba: A. ×boytelii in the Sierra Maestra range, E
Cuba; A. ×medinae in the Trinidad Mountains, Central
Cuba; and A. ×fagildei in the Guantánamo
province, E Cuba. They have spores of normal appearance and might
therefore well be fertile, as suggested by the presence, in the Gran
Piedra area, of a large population of A. ×boytelii; a
full range of intermediates linking this hybrid with its parent
species suggests the occurrence of backcrossing.

fern hybrid Cyathea ×calolepis (Cyatheaceae) and on its
parentage. - Willdenowia 32: 311-318. 2002. - ISSN 0511-9618.
- Cyathea ×calolepis was first collected by Wright in
1856 or 1857 and after 1859 was not found by any other collector
until 1981 when it was rediscovered on the Gran Piedra range in the
Sierra Maestra. It has since been collected in several places in the
Santiago de Cuba province, twice in the Granma and once in the Guantánamo
province, all in E Cuba. It has long been assumed to represent the
hybrid between C. arborea and another, unknown tree fern
species. This assumption is here corroborated, and it is
demonstrated that the second parent is the E Cuban endemic C.
strigillosa.

new nothogenus in the Cyatheaceae (Pteridophyta). -
Willdenowia 32: 281-283. 2002. - ISSN 0511-9618.
- The nothogenus ×Cyathidaria is established to
accommodate various natural hybrids between species of Cyathea
and Cnemidaria, all characterised by abortive spores and
morphologically intermediate between their respective parent
species. ×Cyathidaria acunae, the natural hybrid
between Cnemidaria horrida and Cyathea aspera is a
newly described nothospecies from Cuba. Four new combinations in
×Cyathidaria are made.

Contribution to the flora of Greece: a new species of Arundo
(Poaceae). - Willdenowia 32: 191-194. 2002. - ISSN 0511-9618.
- The new species Arundo hellenica is described from
Greece. It is related to A. plinii but differs in smaller
size of all morphological structures and in the configuration of the
lemma, which, below the awn, is entire at the apex, not bifid as
usually in the genus Arundo. The new species, probably a
Greek endemic strongly confined to disturbed habitats, behaves as an
aggressive weed and may become invasive in other countries.

Quesada, E.: Encyclia altissima (Orchidaceae) new for Cuba.
- Willdenowia 32: 319-321. 2002. - ISSN 0511-9618.
- Encyclia altissima, so far known from the Bahamas, the
Turks and Caicos Islands and Haiti, is recorded for Cuba from the
Sierra de Mariana, Guantánamo province. For the Cuban
population, a description and illustration, distribution data and
conservation status are given.

new species of Campylanthus (Scrophulariaceae) from Ras
Fartak, Al-Mahra, and notes on other species of the genus in Yemen.
- Willdenowia 32: 271-279. 2002.
- Campylanthus hubaishanii, a dwarf shrub from the coastal
mountains of southeastern Yemen, is described as a species new to
science and illustrated. It is the fifth species of the genus known
from mainland Yemen. The new species is compared and a closer
relationship suggested with C. sedoides from coastal Jiddat
al Harasis, central Oman. Based on collections made by the authors
during the last years, new data on the distribution and variation of
C. antonii, C. junceus and C. pungens in Yemen are
also provided.

- Based on own collections made in the southern governorates of the
Republic of Yemen between 1997 and 2002, 110 new and noteworthy
records of vascular plants are provided. Five taxa, Iphigenia
oliveri, Kleinia squarrosa, Parthenium hysterophorus, Rhus glutinosa
subsp. neoglutinosa and Poskea socotrana are
recorded as new for the Arabian Peninsula, and Pistacia aethiopica
is confirmed; 23 species are recorded as new and four are confirmed
for mainland Yemen; 77 species are recorded as new for the southern
governorates of Yemen or larger parts of them. Brief comments are
given on the phytogeography of the taxa. Rhus flexicaulis, a
species hitherto considered an endemic of SW Arabia, is found
conspecific with the widespread African R. vulgaris, and
provides, for priority reasons, the correct name for this species;
the most recently described R. gallagheri from Oman is also
conspecific with it. Justicia areysiana is accepted as the
correct name for the S Arabian endemic formerly known as Bentia
fruticulosa.

revision of Lantana sect. Lantana (Verbenaceae) in the
Greater Antilles. - Willdenowia 32: 285-301. 2002. - ISSN

- The revision of Lantana sect. Lantana for the
projects "Flora of the Republic of Cuba" and "Flora
of the Greater Antilles" confirmed the presence of 10 species
and 16 infraspecific taxa in the territory. Their diagnostic
characters are specified, two new forms are described (L. camara
f. caffertyi and L. flava f. sandersii), the
rank of three taxa is modified, and eight new combinations are
established.

- 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 Amaranthaceae, Basellaceae, Campanulaceae,
Caryophyllaceae, Compositae, Labiatae, Leguminosae, Lythraceae,
Ranunculaceae, Rubiaceae, Scrophulariaceae, Umbelliferae;
Cyperaceae, Gramineae, Liliaceae, and Pontederiaceae. It
includes new country and area records, taxonomic and distributional
considerations. A new species of Scorzonera is described and
illustrated. New combinations are validated in Cladanthus.

- The NW African Hypochaeris arachnoidea is reinstated, a
detailed description of this annual, a full synonymy including
lectotypifications, and a key to the Moroccan species of Hypochaeris
are provided. Chromosome numbers and karyotype information for six
Moroccan Hypochaeris species from ten populations (including
one population from Ireland) are presented and compared with
literature data on karyotypes in the genus.

inventory of the lichen flora of Kalimnos and parts of Kos
(Dodecanisos, Greece). - Willdenowia 32: 351-392. 2002. - ISSN
0511-9618.
- An exploration in the Nomos of Dodecanisos, SE Aegean, Greece,
mainly on the islands Kalimnos and Kos, and to a lesser extent on
Telendos and Nisiros, revealed the presence of 290 lichen species.
Of these, 12 were not recorded before from Greece, and four are
described as new to science: Acarospora pseudofuscata, Buellia
epifimbriata, Caloplaca aegaea and Pertusaria
pseudoparotica. An annotated catalogue is presented, which
includes notes on lichen records from Santorini and Paros. The
lichen flora does not show any special affinity with the nearby
Turkish mainland, in striking contrast to the phanerogam flora. It
is similar to that of the Paros archipelago (Central Aegean Islands)
and differences can be explained by different substrate availability
and chance dispersal (island effect). The lichen flora of Santorini,
a vulcanic island recolonized 3500 years ago, differs by a larger
representation of widespread species. 15 species appear to have a
restricted, eastern distribution in the Mediterranean.

O.: Revision of the genus Ochagavia (Bromeliaceae, Bromelioideae).
- Willdenowia 32: 331-350. 2002. - ISSN 0511-9618.
- The genus Ochagavia is revised. Four species, O.
andina, O. carnea, O. elegans and O. litoralis, are
recognized, all are endemic to Chile. A key to the species,
descriptions, illustrations, full synonymies and data on the
distribution and ecology are given. The new combinations O.
litoralis and O. andina are validated, and several names
are typified. Relationships of the genus within the subfamily
Bromelioideae are discussed.
