Lennoaceae is a family of parasitic flowering plants of south-western North America and north-western South America. The hierarchy of scientific classification In biological classification, family (Latin: familia, plural familiae) is a rank, or a taxon in that rank. ... About 4,100 species in approximately 19 families of flowering plants are either partly or completely parasitic on other plants [1]. Parasitic plants have a modified root, the haustorium, that penetrates the host plant and connects to the xylem or phloem or both. ... Classes Magnoliopsida - Dicots Liliopsida - Monocots The flowering plants or angiosperms are the most widespread group of land plants. ... North America North America is a continent[1] in the Earths northern hemisphere and (chiefly) western hemisphere. ... South America South America is a continent crossed by the equator, with most of its area in the Southern Hemisphere. ...

The relationships of this family with other plants remain uncertain, and the family has been placed in different orders by different authors, including Lamiales (in the Cronquist system) and Solanales (Dahlgren system). Molecular phylogenetic publications have grouped the Lennoaceae within the clade "Euasterids I", and most recently, it was subsumed into the family Boraginaceae in the APG II system ^[1]. In scientific classification used in biology, the order (Latin: ordo, plural ordines) is a rank between class and family (termed a taxon at that rank). ... Families See text The Order Lamiales is a taxon in the asterid group of dicotyledonous flowering plants. ... A system of plant taxonomy, the Cronquist system is a scheme for the classification of flowering plants (or angiosperms). ... Families at least the following: Solanaceae Convolvulaceae and others, varying between classification systems; for details see text The Solanales are an order of flowering plants, included in the asterid group of dicotyledons. ... One of the modern systems of plant taxonomy, the Dahlgren system was published by monocot specialist Rolf Dahlgren. ... Molecular phylogeny is the use of the structure of molecules to gain information on an organisms evolutionary relationships. ... A clade is a term belonging to the discipline of cladistics. ... Genera many, see text Boraginaceae Juss. ... A modern system of plant taxonomy, the APG II system of plant classification was published in 2003 by the Angiosperm Phylogeny Group, APG, in Angiosperm Phylogeny Group (2003). ...

The family has a disjunct distribution, occurring in Colombia as well as a separate area in south-western North America, covering parts of California, Arizona and Mexico ^[2].

The family comprises up to three genera, Ammobroma, Lennoa and Pholisma, which between them hold around five species, including the desert christmas tree, Pholisma arenarium and sandfood, Pholisma sonorae ^[3]. The genus Pholisma Nutt. ...

Members of this family are succulent, herbaceous plants with no chlorophyll ^[4]. The leaves are reduced to short scales, and the plants are entirely parasitic on the roots of their hosts, which are typically Clematis, Euphorbia, and various woody Compositae ^[4]. Succulent plants, or succulents, are plants that store water in their enlarged fleshy leaves, stems, or roots. ... Herbs: basil Herbs (IPA: hÉ™()b, or É™b; see pronunciation differences) are seed-bearing plants without woody stems, which die down to the ground after flowering. ...
