The Santalales are an order of (Plants having seeds in a closed ovary) flowering plants, belonging to the (Flowering plant with two cotyledons; the stem grows by deposit on its outside) dicotyledons.
Most are partially (Click link for more info and facts about parasitic) parasitic - they can produce food through (Synthesis of compounds with the aid of radiant energy (especially in plants)) photosynthesis, but tap the stems of roots of other plants to obtain water.
These are no longer considered close relatives of the Santalaceae, but at the moment their placement is still uncertain.

As currently classified, Santalales consists of 7 families of autotrophs, root- and aerial parasites.
The present analysis include 51 genera of Santalales, 18 of which belong to Olacaceae (from a total of ca.
As in previous analyses, Santalales are monophyletic with Opiliaceae, Loranthaceae and Viscaceae monophyletic and Santalaceae and Olacaceae paraphyletic.

 Santalales
Malécot (2002) provides a phylogeny based on the analysis of variation in four genes that emphasises members of the old Olacaceae; he discusses variation of morphological characters in the context of this phylogeny and also provides analyses of a combined morphological-molecular data set.
Distinct ovules may not be recognizable, the embryo sacs being borne in a spherical body, the mamelon; this consists of a basal placenta and everything else.
In the stem/branch parasites, the host-parasite junction may be much swollen, producing wood roses in the host; the precise morphological nature of the association bewteen stem parasite and hosts varies (e.g.

To better understand the diversification of ovule morphology among angiosperms, I have initiated studies on the ovules of members of the order Santalales, an order of mainly parasitic plants that includes mistletoe and sandalwood.
The Santalales includes species with ovules similar to those found in most other angiosperms (bitegmic), but also has members with very reduced ovules compared with the rest of the angiosperms.
For some species one or both integuments are absent (unitegmic or ategmic respectively) and in others, ovules are not seen to emerge from the underlying placental tissues (characterized as not being true ovules).

In collaboration with Daniel Nickrent of Southern Illinois University at Carbondale we are examining the extreme reduction in ovules of members of the order Santalales, which includes mostly parasitic plants.
The Santalales includes species with bitegmic (two integuments) ovules but also has members with one or both integuments absent (unitegmic or ategmic respectively).
In the most extreme reduction, ovules appear to be absent, never emerging from the placental tissues, and the embryo sac appears to develop directly within the placenta.

 Parasitic Plant Definition   (Site not responding. Last check: 2007-10-20)
An obviuos one is presented by the epiphytic members of Santalales (Eremolepidaceae, Misodendraceae, some Santalaceae, Loranthaceae, and Viscaceae), where parasitism secures (at least) a steady supply of water for the parasite.
Another evolutionary advantage is conveyed by the ability of parasitic plants to spend larger proportions of their life cycle on reproduction than their hosts.
Because of the enormous number of species (>2000), Santalales (only approaching holoparasitism in very few cases) have been omitted here.

 introduction to web site
Inclusion of the family Grubbiaceae has been fairly recent and there is still some question as to the exact relationship.
This family has often been placed in the order Santalales because of the structure of its pistil.
There are, however, other features which cause it to be misplaced in the Santalales including anatomical differences, its autotrophic not parasitic habit, and no close relationships to any other family in the Santalales.

Santalaceae is a cosmopolitan family of root and stem hemiparasitic plants in the Sandalwood order (Santalales).
The mistletoe habit has evolved independently twice in Santalaceae and in three other families in Santalales (Misodendraceae, Loranthaceae, and Viscaceae).
Preliminary work on other genes show promise for resolving deep-level nodes, at which time main clades will be recognized as a formal family-level classification.

Analysis of 100 species of plants including families of subclasses Rosidae, Hamamelidae, Dilleniidae, and Caryophyllidae (sensu Cronquist) placed monophyletic Droseraceae in the same clade as Caryophyllidae and Nepenthaceae (Dilleniidae).
In a second analysis of 14 species of Droseraceae, 15 caryophyllids, one Nepenthaceae, and three Santalales, a single most-parsimonious tree was found in which Droseraceae are monophyletic, although the position of Drosophyllum as a member of Droseraceae is only weakly supported.
The rbcL tree identified four major lineages within genus Drosera: 1) Dionaea; 2) the regia-clade that contains only Drosera regia; 3) the capensis-clade that contains the South African and temperate species outside of Australia; and 4) the peltate-clade that consists of principally Australian endemics.
