DRAWER 01 · Pinaceae
Ponderosa pine
Raised woody scales, often with a short prickle. A broad cone with robust scale faces. The small central point varies; it is not equally sharp on every scale. Pinus ponderosa
Cone length: 50–150 mm. Species-wide range; not a Bryce population measurement. Seed body: 4–9 mm. Seed body; occasional 3 mm bodies also reported. 15–25 mm wing.Cone source · Seed source
A compact cone with large, blunt scale faces. The opened cone becomes rounded and broad. Its large wingless seeds contrast with the winged ponderosa seed. Pinus edulis
Cone length: 35–50 mm. About 40 mm in the FNA account; endpoints include its parenthetical limits. Seed body: 10–15 mm. Seed body only. Wingless.Cone source · Seed source
Thick, smooth scale ends without prickles. The long cone and unarmed scales separate this form from the smaller bristled cone in the next drawer. Pinus flexilis
Cone length: 70–150 mm. Range-wide cone length. Seed body: 10–15 mm. Seed body only; a small residual wing may occur. Wingless or nearly so.Cone source · Seed source
Slender bristles rise from thickened scale faces. A pointed outline carries the namesake bristles. Their described length is 1–6 mm; the drawing uses a 5 mm example. Pinus longaeva
Cone length: 60–95 mm. Range-wide cone length; bristles are variable. Seed body: 5–8 mm. Seed body only. 10–12 mm wing.Cone source · Seed source
Three-pointed bracts project between the scales. Each bract has a long middle tip and two shorter side tips. It is a separate structure from the rounded seed scale. Pseudotsuga menziesii var. glauca
Cone length: 40–70 mm. Rocky Mountain variety glauca; not the larger coastal variety. Seed body: 5–6 mm. Species-level seed body range. Wing drawn 1.8× body for explanation; only “longer” is sourced. Wing longer than body.Cone source · Seed source
Upright cylindrical cones with overlapping fan-shaped scales. A fir cone comes apart scale by scale. The central axis stays on the branch after the scales and seeds separate. Abies concolor
Cone length: 70–120 mm. FNA also reports width 30–45 mm. Drawing uses 37.5 mm. Seed body: 8–12 mm. Seed body only; wing length is approximate, not an independently measured interval. Wing about 2× body.Cone source · Seed source
Thin, flexible scales give the cone a papery edge. The mature cone hangs down. The wavy scale margins in this drawing emphasize texture; they are not a microscope record. Picea pungens
Cone length: 64–102 mm. USDA FEIS range; other botanical accounts use somewhat different endpoints. Seed body: about 3 mm. Approximate value in USDA FEIS, not a measured range or Bryce sample. Wing about 2× body.Cone source · Seed source
A rounded cone whose scales are fused together. Its berry-like outline belongs to a cone. A pale waxy bloom covers a darker surface; two seeds are a typical example. Juniperus scopulorum
Cone diameter: 6–9 mm across. Diameter, not cone length. Much smaller than the woody cones. Seed body: 4–5 mm. Individual seed body; number per cone usually two, occasionally one or three. Wingless.Cone source · Seed source
Separate woody scales and fused berry-like scales are both cone structures. Juniper is shown enlarged independently.
Plate 02 · Open to read
A short point and a long bristle
Both points belong to the scale. Bristlecone prickles vary from 1–6 mm; a ponderosa scale may carry only a small point.
Plate 03 · Open to read
Thick scales do not always have a spine
Pinyon and limber pine have thickened, unarmed scale faces. Cone size and seed traits supply additional clues.
Plate 04 · Open to read
Three tips, one bract
The long middle tip and two shorter tips belong to a bract beneath the seed scale. They are not three seeds.
Plate 05 · Open to read
Papery margins and woody faces
Blue spruce has thin, flexible scales. Ponderosa has thickened scale faces. The textures are drawn schematically.
Plate 06 · Open to read
Hanging down or standing upright
Mature Douglas-fir seed cones hang; true fir seed cones stand upright. This compares mature posture, not an entire growth cycle.
Plate 07 · Open to read
The column that remains
True fir releases its scales individually. The persistent axis explains why a complete cone is not its usual final form.
Plate 08 · Open to read
A pair on each fertile scale
In the pine family, each fertile scale has two seed positions on its upper face. Not every position becomes a filled seed.
Plate 09 · Open to read
A wing changes the outline
Ponderosa has a long wing; pinyon is wingless. These enlarged portraits compare structure, not equal magnification.
Plate 10 · Open to read
Small bodies, broad silhouettes
The seed body and its wing are different measurements. Spruce is about 3 mm; white fir is 8–12 mm, excluding the wing.
Plate 11 · Open to read
A cabinet is not a ruler
Published intervals describe variation across source treatments. They are not local averages. Juniper uses diameter; the others use length.
Plate 12 · Open to read
Inside a berry-like cone
Fused cone tissue surrounds usually two wingless seeds, sometimes one or three. This section is an explanatory layout.
Read the form. Keep the limits in view.
Original botanical illustrations. No collected Bryce specimens, scans or field measurements. Shape, color, scale count and interior layout are schematic. Dimensions come from published descriptions; they are not measurements made here. Color and posture vary with maturity. This is a form study, not a complete identification key. No eating, collecting or propagation guidance is provided.
