1 Species New to Science discovered and described by Avinoam Danin Ferula daninii Zohary Flora of Israel online
2 Origanum ramonense, endemic to a small area of the Negev Highlands, confined to smooth-faced limestone
3 Origanum ramonense In the greenhouse In the field

8 A 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
9 Rock outcrops and an asphalt road where runoff started
10 Urginea maritima at a soil pocket in smooth-faced rock outcrop covered with epilithic lichens (P=100 mm)
11 A cross-section in a limestone covered with an epilithic lichen which protects it from the destructive energy of the rain drops epilithic lichen rock
12 Water in a depression at a rock-outcrop in the desert. Soil pockets should be regarded as such depressions filled with soil
13 A soil pocket in the desert. The marked plants are typical Mediterranean surviving due to efficient run-off from the exposed smooth rock (P=80 mm) Umbilicus intermedius Urospermum picroides
14 Bufonia ramonensis, endemic to one slope at the Negev Highlands, in the same rock outcrop of the two previous photos
15 Gebel Halal in N Sinai (P= 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
16 A Juniperus phoenicea branch, 865 years old; seems to be the oldest tree recorded in the Middle East so far
17 Juniper 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
18 Juniperus phoenicea branches resemble those of Cupressus, but the small cones look like red fruits
19 Eastern Crete where Juniperus phoenicea shrubs are accompanied by Sarcopoterium and Coridothymus
20 Large 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
21 Origanum jordanicum, the closest relative of O. isthmicum
22 Distribution of Origanum sect. Campanulatocalyx 1. O. dayi 2. O. ramonense 3. O. isthmicum 4. O. punonense 5. O. petraeum 6. O. jordanicum
23 In 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 recovering of the exposed roots in areas of sand deflation Moltkiopsis ciliata Heliotropium digynum
24 A gentle slope of a sandy area south of Dimona supports several Boraginaceae. It is facing southwest, the main direction of strong winds in winter
25 A species new to science, described as Anchusa negevensis confined to that slope and was not found anywhere else. It produces root-borne shoots
26 Following DNA analyses of the family the species was transferred to another genus, and it is now Hormuzakia negevensis
27 A group of at least 7 individuals of H. negevensis that are possibly connected by their roots
28 New root-borne shoots of H. negevensis
29 Flowers and fruits of H. negevensis
30 Theucrium capitatum a common species of Israel and its neighbouring countries
31 Hair-types of the taxa related to Teucrium leucocladum, compared to those of T. capitatum subsp. leucocladum subsp. jordanicum subsp. sinaicum var. glandulosum T. capitatum
32 Distribution of the taxa related to Teucrium leucocladum

Danin (additional one Cyanobacterium, probably Mathea daninii Friedmann, is in press since 1984).
