Datisca glomerata

Wildflowers Dicots Cucurbitales Datiscaceae Datisca

Durango Root

Seen budding on Blue Canyon trail in late May, blooming mid-June-July. On the edge of a stream. Leaves are toothed and lobed. 3~4 feet high. Stem is not square.

Seen at many stream crossings on Blue Canyon, at a damp spot (winter stream) on the backside of Cold Spring trail, in a bog beside the backside of Romero road, and at the place where Seven Falls/Jesusita trail crosses Mission Creek.

    Because these buds are not open, it is difficult to be sure of color, but the verticillasters typify Lamiaceae and lead me to Mentha Arvensa. The sawtooth leaves are more dramatic than most M. arvensa, but environmental circumstances can enhance laminar morphology. The crowded florets still take me to M. arvensa, and the apparent height of your spec suggests a typical habit which can achieve 40″+ of growth. If the leaf arrangement is distictis, that would be an inch closer. You may disregard some of the available photos showing leaves of some of these plants with entire margins and elliptic in shape. These are often misidentified and, normally do not bespeak of Lamiaceae genera.

    Good Luck (Review several sites) Use Cliff Smith andT.E. Niehaus for text refs.

      Thank you! I’ll go back and try to find it again, it’s probably in bloom now. I’m a bit concerned because not only are the leaves sawtoothed, they are also deeply lobed, and I don’t see any mention of that in Jepson for M. arvensa (but nothing to contradict it either).

      Hmm. It is now flowering, and the flowers don’t look like much of anything, not like M. arvensis. The stem isn’t square (of course not all mints have square stems), and the leaves are deeply lobed.

    I went to http://www.botany.hawaii.edu and found a fairly good shot of M.arvensa. Check out the leaves.

    ps.: I meant “decussate” in ref to the leaf pairs arrangement, not Distictis.

    In Lamiaceae (I am not giving up) try MSN BING search:

    California lycopus photo

    In Panels (panels have 4 thumbnails) #1,2,5 and particularly, 6 (Strandklo) see L. europaeus. I am not fam with Lycopus, nor can I deduce origin of escape status of this obscure mint, but you might give it a try. Flowers are white and Strandklo’s floiar shot is particularly unruly.
