|
| Nomenclature |
Species name: |
Ophrys mesaritica P. Delforge |
Author(s): |
Pierre Delforge; Belgium, 20th Century
|
General names: |
Cretan Blue Orchid, Early Rainbow Orchid |
Maltese name: |
Dubbiena bikrija |
Plant Family: |
|
Name Derivation: |
Ophrys = "Eyebrow", referring to the furry edges of the lips of several species. (Greek);
mesaritica = Belonging to Mesara, the largest plain in Crete, Greece; since here was where the plant was described first. (Latin). |
Synonyms: |
Ophrys iricolor subs. mesaritica. Ophrys fusca - rather than a synonym, this taxon is more a general name given to a group of species (including O. eleonorae), which look like Ophrys fusca. |
Remarks: |
This plant was previously placed under Ophrys fusca s.l. a complex aggregate which is being split into a number of different species. It was thought to be endemic to the region of Mesara in Crete, till the year 2000 when it was found by P. Delforge in Malta. Recently DNA analysis was made on this dubious species and the results of the Maltese species do not match those of the Cretan ones. Thus this might be an endemic orchid. -

Characteristic | Inflorescence | Description | Ovary | Stamens |
Description | Spike : Unbranched, elongated, indeterminate inflorescence with sessile flowers. | Flower consists of 3 identical leaf-like outer segments (= sepals) and 3 inner segments (= petals) of which 2 are small and green and the other is a modified lip-shaped petal called labellum. The labellum colour is dark brown with a blue-violet maculum (patch), and has 3 distinct lobes. Its margins are curved down and has a velvetly texture. Alike the other Ophrys species of the Ophrys iricolor group, the sides of the labellum near the mouth entry have 2 elevated ridges. | Inferior : Ovary situated below the flower parts (the calyx, corolla, and androecium). In other words, these are attached above the ovary. | Pollinia x 2 : No true stamens but a pair of small pollinia which are specialized structures in Orchids that are covered by a mass of waxy pollen or coherent pollen grains and have a sticky base. |

Ophrys mesaritica is similar in morphology to O. fusca and its full morphological description can be read by [clicking here...] The main differences which distinguish O. mesaritica from the other closely related species of Ophrys fusca are the following:
1) The flower has distinctive, elevated ridges at the edges of the inner end of the labellum, that is at the mouth of the flower.
2) The length of the labellum is rather short, measuring between 11-16mm.
3) The plant flowers between mid December and February, which makes it the earliest to flower from the Ophrys fusca related group of species. An orchid looking like Ophrys fusca and is seen to flower in Malta during January, is most probably to be Oprhys mesaritica .

Nativity and distribution
According reference [WWW-03] the Genus Ophrys is native to the Mediterranean region.
Ophrys mesaritica was first described by Paulus, C. Alibertis and A. Alibertis (1990) in a plain called Mesara (and hence the name mesaritica) in the large Greek island of Crete. It was originally named as Ophrys iricolor subsp mesaritica, but after nomenclature changes its name is currently accepted as Ophrys mesaritica by Delforge. [WWW-148] Since it was believed to be found only in Crete, Ophrys mesaritica was considered as an endemic to Crete. In 1993, Delforge discovered the presence of Ophrys mesaritica in Malta.[369] This puts some questions about the distribution of the plant since it is found in 2 islands so far away from each other [SM]. Additionally Delforge states that it also occurs on the E. Aegean island of Lesvos, but the latter is rather doubtful at this stage of research. [WWW-148]
Reports about Ophrys mesaritica in Malta.
In the report [367], members of the 'Ophrys fusca complex' that are found on the Maltese islands are given after research by 4 botanists (G.Bartolo, S.Pulvirenti, E.lanfranco, D .Stevens) in 2001. The following 5 species are given:
Ophrys fusca Link,
O. caesiella P. Delforge,
O. parosica, P. Delforge,
O. pectus Mutel,
O. mesaritica P. Delforge (Iricolor group)
N.B. Ophrys pectus is a hybrid of Ophrys bilunulata (A1: Ophrys iricolor complex group) x O. mesaritica (A2: Ophrys mesaritica complex group) [WWW-142]
According to the Belgian Delforge who dedicated much work on the Ophrys group and visited Malta during the end of February, indicated that the following species are found:
O. mesaritica P. Delforge
O. lupercalis J. Devillers-Terschuren & P. Devillers
O. pectus Mutel
O. fusca Link (possibly)
But during his stay in Malta, Delforge did not encounter O. parosica (fusca complex), or O. eleonorae from the Iricolor complex. .
Species of the Ophrys iricolor complex.
This complex or aggregate is made up of five species which are closely related to each other and previously they where referred to as Ophry iricolor s.l. or lumped with the Ophrys fusca s.l. The main charactaristic of this group is that of having an elevated ridge at the rim near the mouth / base of labellum. Some are quite narrow endemics. In Malta, there appears to be three species, O. mesaritica, O. eleanorae and O. vallesiana (?) [WWW-147]
- Ophrys eleonorae J. Devillers - Terschuren & P. Devillers
- Ophrys iricolor Desfontaines
- Ophrys lojaconoi P. Delforge
- Ophrys mesaritica P. Delforge
- Ophrys vallesiana J. Devillers - Terschuren & P. Devillers
Recent DNA analysis
The doubt whether this Maltese plant is actually the Crete-endemic O. mesariica always existed. Morphologically our species is quite similar to that in Crete, but the distrubation does not give a plausible explanation. Recentely, a DNA analysis of the two specimen (Maltese and Cretan) was carried out and the results showed that they are different! [MB] Further studies are being carried out, but now one can exclude O. mesaritica from Malta. We have to wait if our species would be given a new taxon or grouped with another Ophrys. [SM]
