Oxalis elegans.

Oxalis decaphylla (Hutchins 9837), from Catron County NM.

My first paper. I feel happy of myself.

Maximum likelihood phylogeny of combined nrITS and plastid datasets. Parsimony bootstrap scores are above branches and Bayesian posterior probabilities are below. Bolded species names indicate distylous individuals. Branch lengths are proportional to the inferred number of nucleotide changes along them. The length of the branch leading to O. corniculata has been reduced by half.

Heterostyly in the American bulb-bearing Oxalis. Floral morphs associated with tristylous and distylous breeding systems. Arrows indicate legitimate pollen transfer (Darwin, 1877). In fully functioning heterostylous breeding systems, pollinations other than those indicated by the arrows do not result in fertilization of ovules. Redrawn from Weller, et al. (2007).

Maximum parsimony strict consensus topologies from separate nrITS (88 sequences from 76 individuals, 760 sites, 30% pars. informative) and plastid (71 accessions, 2867 sites, <8% informative) datasets. Bolded species names indicate distylous individuals. Parsimony bootstrap scores are above branches and Bayesian posterior probabilities are below. Incongruence occurs in the placement of O. rosea, and in the order of divergence in the Andean lineages.

Bulb and succulent root of a two year old Oxalis macrocarpa (AG49). There are four bulblets on ~1/2 cm stolons; three are visible. The root has begun to contract, noticeable in its folded epidermis. The scale bar is 1 cm.

Oxalis decaphylla (AG126); Gila NF, New Mexico.

Two different populations (by row) of Oxalis bipartita ssp. Pabstii. Leaf heteroblasty.

Oxalis perdicaria!

I love the blue paper.

Oxalis calva(?) on the edge of Santa Catarina, about 1200 m. This is a mid from a trimorphic population.

Botanists get excited when an herbarium sheet is so expressive. The bulbs of this look much like the collection we made on top of Morro de la Igreja. O. potamophila?

Oxalis bipartita, on the side of the road, near Palmeira. They’re just stretching out their first leaves.
