distribution and morphological data of Vulpia membranacea.
– Willdenowia 31: 309-313. 2001. – ISSN 0511-9618.
- Vulpia membranacea is more widespread than supposed
before. Specimens from W Germany, N Greece, S Macedonia, Israel, the
Balearic and Canary Islands, considerably extending the total range
of the species, are listed and dot-mapped here for the first time.
Stomata measurements in the newly investigated material partly
disaccord with the previously reported correlation of stomata size
and chromosome numbers of 2n = 14 and 2n = 28, questioning the
ploidy level as a differentiating character of the closely related
species V. membranacea and V. fasciculata. Unusual
lemma scabrosity in specimens from the Canary Islands is documented
by REM photographs.

- Continuing a series of miscellaneous contributions, by various
authors, where hitherto un- published data relevant to the
Med-Checklist project are presented, this instalment deals with the
families Berberidaceae, Boraginaceae, Chenopodiaceae,
Compositae, Convolvulaceae, Crassu- laceae, Cruciferae, Droseraceae,
Elatinaceae, Euphorbiaceae, Juglandaceae, Labiatae, Legu- minosae,
Scrophulariaceae, Solanaceae, Umbelliferae, Valerianaceae;
Cyperaceae, Hydrocha ritaceae, Gramineae, Pontederiaceae, and
Potamogetonaceae. It includes new country and area records,
taxonomic and distributional considerations. A new combination is
validated in Gymnospermium.

phytogeographical significance of the islands Chrisi, Koufonisi and
nearby islets (S Aegean, Greece). – Willdenowia 31: 329-356.
2001. – ISSN 0511-9618.
- An annotated floristic catalogue is provided for the islands
Chrisi (Gaidouronisi), Koufonisi and the nearby islets Mikronisi,
Strongili, Makrouli and Trachilos, all off SE Kriti. Critical use is
made of literature data, and hitherto unpublished records, mostly
from 1997 through 2000, add substantially to the first full vascular
plant inventory of the islands. The total numbers of vascular plant
taxa currently known from each island are as follows (accepted taxon
records from literature, if extant, in brackets): Chrisi 275 (162),
Mikronisi 71 (21), Koufonisi 273 (71), Strongili 110, Makrouli 115,
Trachilos 96. Most noteworthy are Suaeda palaestina and
Ononis vaginalis (currently with their single localities in
Europe); Allium brachyspathum, Astragalus boeticus, A.
peregrinus, Galium recurvum, Hippocrepis unisiliquosa, Lagurus
ovatus subsp. nanus, Ononis diffusa, Orobanche grisebachii,
Schoenoplectus litoralis (new records or confirmations for the
Cretan area as a whole, or for the territory of Kriti proper
including offshore islands); and Chlamydophora tridentata,
Frankenia corymbosa and Hymenolobus procumbens (new
regional records for the E part of Kriti and its offshore islands).
The N African, pronouncedly thermophilous phytogeographical element
is fairly well represented in the investigated area, thence
Koufonisi in particular must be considered the driest and hottest SE
European island. The principal habitats encountered in each of the
islands are outlined and the present conditions for nature
conservation discussed.

mirabilis (Welwitschiaceae), male cone characters and a new
subspecies. – Willdenowia 357-381. – ISSN 0511-9618.
- Based on the observation of male cones in plants of old stock of
Welwitschia mirabilis cultivated in the Botanic Garden
Berlin-Dahlem and documented in the garden herbarium, two groups can
be distinguished. Plants of "group 1" are characterized by
short peduncles and long, purplish brown male cones with widely
overlapping bracts. Plants of "group 2" are regularly
flowering about three weeks later and have usually longer peduncles
but shorter male cones which are glaucous-green to salmon coloured
and more "sculptured" due to different bract shape and
less overlapping bracts. Tracking the incompletely documented origin
of these accessions revealed that some of the over 50 years old
plants were grown from seeds received from Coimbra originating from
Angola and others from seeds received from Kirstenbosch originating
from Namibia. Published illustrations of male cones provided only
limited further evidence on cone characters. Examination of
herbarium specimens of known origin showed that male cone characters
fully agreeing with those of group 1 occur in material from Angola,
whereas cone characters of plants of group 2 are typical for
specimens from Namibia, particularly from the Swakop area. The
differences suggest the existence of two subspecies. The
controversial nomenclature of W. bainesii and the reasons
for avoiding this epithet for the subspecies are briefly discussed.
Instead the new combination W. mirabilis subsp.
namibiana is validated. A lectotype is designated for the
binomial W. mirabilis. As a further result, a total of three
male cones with bracts arranged in verticils of three, instead of
the regular two, were found among more than 3000 cones screened. One
was found on a plant of group 1 grown at Berlin-Dahlem, one in a
sample originally received from J. D. Hooker probably of Angolan
origin, and one in a herbarium specimen from Namibia.

- Continuing a series of miscellaneous contributions by various
authors, this second instalment includes data on 174 vascular plant
taxa of Cyprus, concerning mainly chorological aspects. Setaria
adhaerens var. fontqueri and Saccharum strictum
are new records for the island. Chromosome numbers are given for
Glaucosciadium cordifolium (2n = 18, first count for this
species), Nigella nigellastrum (2n = 12) and Valantia
hispida (2n = 18). New taxonomic considerations result in the
new combinations Scutellaria cypria subsp. elatior
and Valantia hispida var. eburnea.

- Chromosome numbers (somatic and gametic) of 21 species of eight
families of angiosperms, collected in the wild in Kuwait, are
reported. Most of them are the first counts in Kuwaiti populations.
Included are the first report for Anisosciadium lanatum (2n
= 18) and new numbers for Aizoon hispanicum (2n = 18), Astragalus
annularis (2n = 24) and Pallenis hierochuntica (2n =
12). The karyotypes of Astragalus annularis and A.
spinosus are illustrated.

spinosum (Verbenaceae) in the Antilles. – Willdenowia 31:

- As part of the revision of the genus Citharexylum for the
projects "Flora of the Cuban Republic" and "Flora of
the Greater Antilles", conspecificity of C. spinosum
and plants assigned by many authors to a different species, misnamed
"C. fruticosum" (an illegitimate name), is
demonstrated. Infraspecific classification of C. spinosum is
critically reconsidered, resulting in five new combinations, three
of them at a new rank.

Polygala guantanamana (Polygalaceae), a Cuban endemic species.
– Willdenowia 31: 425-431. 2001. – ISSN 0511-9618.
- The forthcoming Polygalaceae treatment for the "Flora
de la República de Cuba" will recognize four shrubby
Polygala species instead of the eight that had been
previously described. One of them is P. guantanamana, easily
recognized by its glabrous pedicels. A broadly based revision
permits to distinguish two subspecies in it. P. guantanamana
subsp. guantanamana is found in coastal habitats of
southeastern Cuba and in xeric vegetation, mostly on ophiolithic
soils, in central and western Cuba. The newly described subsp. alternifolia
grows in that same kind of inland habitats but is limited to eastern
Cuba. P. scabridula, a characteristic morph which is limited
to and prevalent but not exclusive in the central and western Cuban
populations, is given varietal rank within subsp. guantanamana.

- Life and work of August Schlickum (1867-1946), a high school
teacher and amateur botanist at Cologne, is presented in some
detail. Schlickum's Hieracium collection, which comprises c.
7100 specimens, including several types, as well as material from
other collectors, was acquired in 1949 by the Botanical Museum
Berlin-Dahlem (B) and is now being incorporated into the general
herbarium.
