Detailed Information
Flower: 
![[photo of flowers]](/udata/r9ndp23q/pd/lithospermum-incisum-19.jpg)
Trumpet-shaped yellow flowers, ½ inch across, 5 lobes with ruffled or crinkled edges at the end of a slender, ¾ to 1¼ inch long tube. At the base of the tube are 5 narrowly triangular sepals, much shorter than the tube and densely covered in appressed hairs. Flowers are very short-stalked, crowded at the tip of the stem, with a small leafy bract at the base of the stalk. These showy flowers are mostly sterile. Later in the season, self-fertilizing, petal-less flowers (cleistogamous flowers) develop, which are mostly inconspicuous.
Leaves and stem:
![[photo of leaves]](/udata/r9ndp23q/pd/lithospermum-incisum-4.jpg)
Leaves are narrowly lance-linear, 1 to 3 inches long and not more than ¼ inch wide, pointed at the tip, toothless, stalkless, and have a prominent central vein. Surfaces are covered in short, appressed hairs, the lower surface more densely so and pale gray-green. Stems are mostly erect and unbranched, and covered in short appressed hairs.
Fruit:

Fruit is an egg-shaped nutlet, pitted across the surface, ripening to shiny white.
Notes:
Narrow-leaf Puccoon is easily recognized by the frilly, yellow flowers and narrow leaves.

I'm not positive that my ID is accurate, but I'm fairly certain. I'm sure it's a Borage. It's growing densely on the side of a gravel road, but only in a small area. I know that some of the Borage family is fragrant, but I find no mention of this being fragrant. My sample is very fragrant.

I positively identified these in one of my pastures today. A huge patch of them are growing on a south facing rocky slope close to an area where we pick mayflowers. Absolutely beautiful.
