8A hard rock outcrop during a light shower (ca. 1
mm/hr). The shiny faces are sites where a
continuous water film developed on the rock and
run-off started
9Rock outcrops and an asphalt road where runoff
started
10Urginea maritima at a soil pocket in smooth-faced
rock outcrop covered with epilithic lichens
(P100 mm)
11A cross-section in a limestone covered with an
epilithic lichen which protects it from the
destructive energy of the rain drops
epilithic lichen
rock
12Water in a depression at a rock-outcrop in the
desert. Soil pockets should be regarded as such
depressions filled with soil
13A soil pocket in the desert. The marked plants
are typical Mediterranean surviving due to
efficient run-off from the exposed smooth rock
(P80 mm)
Umbilicus intermedius
Urospermum picroides
14Bufonia ramonensis, endemic to one slope at the
Negev Highlands, in the same rock outcrop of the
two previous photos
15Gebel Halal in N Sinai (P80-100 mm), where
Juniperus phoenicea trees survived in
smooth-faced rocks. They penetrated the desert in
a moist period more than 40,000 years ago. A
branch of the marked tree displays 865 annual
rings
16A Juniperus phoenicea branch, 865 years old
seems to be the oldest tree recorded in the
Middle East so far
17Juniper trees in a wadi draining the large rocky
surface attain considerable size, also by being
naturally protected from becoming fire wood. The
burning wood explodes and makes sparks which
may endager the Bedouin tent
18Juniperus phoenicea branches resemble those of
Cupressus, but the small cones look like red
fruits
19Eastern Crete where Juniperus phoenicea shrubs
are accompanied by Sarcopoterium and Coridothymus
20Large rock outcrops of Gebel Halal support
additional special plants among the Juniper trees
Origanum isthmicum discovered here is endemic to
an area less than 5x5 km at this mountain chain
21Origanum jordanicum, the closest relative of O.
isthmicum
22Distribution of Origanum sect. Campanulatocalyx
1. O. dayi 2. O. ramonense 3. O. isthmicum 4. O.
punonense 5. O. petraeum 6. O. jordanicum
23In a study of plant adaptations in desert dunes,
several species of the Boraginaceae were
discovered, having the rare ability to produce
root-borne shoots. The new shoots arrest mobile
sand thus leading to the re-covering of the
exposed roots in areas of sand deflation
Heliotropium digynum
Moltkiopsis ciliata
24A gentle slope of a sandy area south of Dimona
supports several Boraginaceae. It is facing
south-west, the main direction of strong winds in
winter
25A species new to science, described as Anchusa
negevensis confined to that slope and was not
found anywhere else. It produces root-borne shoots
26Following DNA analyses of the family the species
was transferred to another genus, and it is now
Hormuzakia negevensis
27A group of at least 7 individuals of H.
negevensis that are possibly connected by their
roots
28New root-borne shoots of H. negevensis
29Flowers and fruits of H. negevensis
30Theucrium capitatum a common species of Israel
and its neighbouring countries
31Hair-types of the taxa related to Teucrium
leucocladum, compared to those of T. capitatum
subsp. leucocladum
subsp. jordanicum
subsp. sinaicum
var. glandulosum
