Summer. Tetraneuris acaulis is short, lovely, and uncommon in the Four Corners area. Stems have no leaves, varying amounts of hair, and often grow in quite noticeable clumps. The plant prefers dry open areas, and those shown on this page are growing in Mancos Shale. Edward Greene named this genus in 1898; "Tetraneuris" is Greek for "four nerves" and "acaulis" means "without leaves on the stem". The plant was first collected for science by Bradbury in North Dakota and Pursh named it Galardia acaulis in 1814. It has endured dozens of other names. There are at least four varieties of T. acaulis and the names are ascribed to a number of different authors. |

Summer. Notice what a great difference there is between the width and length of the ray flowers on the bud at far left and the ray flowers on the fully mature flower heads. Many members of the Sunflower Family show this contrast. Descriptions of plants almost always give you the characteristics of the mature flower. |
