A REVISION OF PHACELIA SUBGENUS COSMANTHUS 5 assigned to Polemonium, the second to Convolvulus, and Michaux was the first to describe any of the species in the correct family and genus. Rafinesque erected the genus Endiplus in for Phacelia bipinnatifida Michx.

In his "Review of the Order of Hydrophylleae," Bentham () placed two. The species of Phacelia reviewed in this paper total 14 and comprise an assemblage designated by Constance () as the subgenus Cosmanthus. The historical back-ground of the subgenus is well presented by Constance and need not be covered here.

The recent experimental study of this assemblage (Gillett,a, b). The status of the subgenusCosmanthus, as revision of Phacelia subgenus Cosmanthus book by Constance, is reviewed in terms of cytological, phytogeographical, and morphological criteria.

Conclusions are advanced that this is an unrelated assemblage of at least five distinct evolutionary groups. These groups, roughly comparable to sections, are delineated and an identification “key” to species is by: 7.

We examined infrageneric relationships within Phacelia subgenus Phacelia based on phylogenetic hypotheses derived from internal transcribed spacers (ITS) and the S gene of nuclear ribosomal DNA.

A Revision of Phacelia Sect. Euglypta John Thomas Howell Introduction Phacelia sect. Euglypta consists of a small group of annual species in which the seeds are transversely wrinkled or corrugated and the corollas early decid-uous.

The two first-named species, Eutoca Cumingii of South America and. Introduction. Litomegachile is a subgenus of Megachile Latreille, a large genus including leafcutting and resin bees. Leafcutting bees are solitary and get their name from their habit of using leaf pieces and other plant materials to form the lining of their nests (Michener ).Although sometimes difficult to separate from other Megachile, certain combinations of characters can be useful in.

Phacelia ranunculacea (Nutt.) Constance was included in subgenus Cosmanthus in the most recent revision of the group (Constance ). The species is found on moist river alluvia in well-shaded habitats of bottomland hardwood forest (Gillett ).

Many of these sites undergo seasonal flooding, a most unusual adaptation for a taxon in Phacelia. A long-term goal of studies of the way in which new species form has been to identify the genes involved, and the forces that drive their evolution.

That goal is now being realized — and natural. Turner, B.L. Systematic reevaluation of the Phacelia patuliflora (Hydrophyllaceae) complex. Phytoneuron Mailed June SYSTEMATIC REEVALUATION OF THE PHACELIA PATULIFLORA Constance, L. A revision of Phacelia subgenus Cosmanthus (Hydrophyllaceae).

Contr. Gray Herb. 1– Moyer, J.A. and B.L. Turner. Three new species ofPhacelia from Nuevo León, Mexico are described and illustrated. Two of these,P. hintoniorum andP. potosina, belong to theCrenulata group; the former, with included anthers, relates toP.

coerulea; the latter, with exserted anthers, relates toP. alba orP. coulteri. The remaining novelty,P. zaragozana, belongs to the subgenusCosmanthus where its closest relationship is withP. Phacelia scavenges for N in the soil and provides C to build soil organic matter. It can be used for feed or hay in soil with low to medium nitrogen availability.

Great root structure breaks up clay soil. Phacelia is a long day plant, flowering only when days are longer than 13 hours (May—Sept). It germinates at temperatures above 37F and winterkills at 18F.

Great root structure breaks up. The subgenus Chilicola (Heteroediscelis) Toro & Moldenke, is notable in that its 10 named species are endemic to Chile (Packer ), where they occupy a broad range of habitats, from the hyper-arid Atacama Desert in the north, to moist temperate forests in the south, occurring at elevations from sea level to over m a.s.l.

Phacelia, genus of species of white to blue or purple-flowering annual herbs, native to North America and Andean South America and including several species of garden flowers. It belongs to the family Boraginaceae. Phacelia campanularia, native to dry slopes of southern California, bears blue, five-lobed blooms in loose sprays over the dark green, toothed, oval leaves on plants about 23 cm.

Common phacelia (Phacelia distans) is an annual herb that blooms in the is also known by the common names blue phacelia and wild scorpionweed, since the clusters of flowers are composed of pale lavender to violet-blue individual flowers arranged in a coil that resembles a curled scorpion’s tail.

Nomenclature of subdivisions within Phacelia Juss. (Boraginaceae: Hydrophylloideae) reflects an update to the classification of the genus, based largely upon the structure offered in summary by Ferguson. We consider this proposed classification a continuation of efforts to better understand interrelationships within the genus and tribe Romanzoffieae Dumort., and anticipate future research.

A year investigation of chromosome number in all 18 genera and more than species (perhaps two-thirds of the total) of the plant family Hydrophyllaceae has not resulted in the discovery either of a single base-number for the family or of a primitive genus, and it has not settled the question as to whether or not the famliy is a strictly natural one.
