Each of the first two has a bony prepollex, rugoseskin on the dorsum, and heavy body.
Each of the last two has a bony prepollex, rather rugose skin on the dorsum, and more squat body.
Occurring sympatrically with Ptychohyla euthysanota euthysanota are several species of Plectrohyla, all of which differ in having a bony prepollex, rather rugose skin on the dorsum, and more squat bodies.
All species of the latter genus have a bony prepollex, rugose skin on the dorsum, and heavy body; also sympatric is Ptychohyla e.
Other hylids sympatric with Ptychohyla spinipollex include three species of Plectrohyla, each of which has a bony prepollex, heavy body, and rugose skin on the dorsum.
The fourth glume is membranous when young, but later on it becomes thick, coriaceous and rugoseat the surface.
Instead of being thin and herbaceous it becomes rigid and hard, smooth or rugose externally as in Panicum.
Glandular hairs on midrib of young leaflets interspersed with sessile, usually yellow glands; lateral leaflets lanceolate, not rugose J.
Glandular hairs on midrib of young leaflets interspersed with stellate clusters of gray glandless hairs; lateral leaflets ovate to broadly lanceolate, rugose J.
In general plan, these rugose corals closely resemble those of our modern reefs; but they differ in their details of structure, and only a very few modern forms from the deep sea are regarded as actual modern representatives.
Zoologists thus separate the rugose or wrinkled corals and the tabulate or floored corals of the Silurian from those of the modern seas.
Posterior tooth quite irregular in form, but the portion above the rugose base or root conical.
The external and internal surfaces of the tooth are about equally convex and somewhatrugose without distinct furrows.
On the centrum of this vertebra lower down is a second much larger rugose articular facet.
The posterior teeth are moderately rugose above the alveoli.
Seventh rib terminates proximally in a single large rugose facet, which connects with a similar facet on side of centrum of seventh thoracic vertebra.
The root of the tooth ends very obliquely and is rugose and irregular.
Leaves large, thick; upper surface rugose and heavily wrinkled; lower surface dull, pale green with a bronze tinge, faintly pubescent.
Its strikingly rugose or wrinkled surface distinguishes it from other cherries.
Hymenium dark cinereous, rugose when moist, the minute crowded irregular folds abundantly anastomosing; nearly even when dry.
The head is adorned with two erect rugose spines; the segments have dorsal rows of branching spines, and three lateral rows on either side of the shorter spines.
The caterpillar in its mature state is cylindrical, somewhat thicker before than behind, with the second segment adorned with two prominent rugose club-shaped tubercles.
Forms of fuliginosus approach lignyotus in color, and the =pileus= sometimes is rugose wrinkled, while in lignyotus pale forms occur, and the pileus is not always rugose wrinkled.
In age it becomes flesh color the entire length and is more plainly striate rugose with a yellowish tinge at the base.
It is distinguished from the latter by the dark brown color of the pileus and by the presence usually of rugose wrinkles over the center of the cap.
Columnaria alveolata, a Rugose compound coral, with imperfect septa, but having the corallites partitioned off into storeys by "tabulæ.
So far, therefore, as at present known, all the characteristic genera of the Rugose Corals of the Carboniferous had become extinct before the deposition of the limestones of the Middle Permian.
The leaves are linear-lanceolate, and covered with a dense silvery tomentum on the under side, somewhat rugose above, and partially deciduous.
The moderately rugose dorsum (in males), large size, extensive webbing on the hand, and frontoparietal flanges in adults serve to distinguish taurinus from other members of the genus.
The skin on the top of the head in taurinus is rugoseas a consequence of co-ossification.
Leaves below medium to large, irregularly roundish, dark green, rugose on older leaves; lower surface tinged with bronze, pubescent.
Leaves large and thick; upper surface rugose and often heavily wrinkled; lower surface dull, pale green with slight bronze tinge, faintly pubescent; veins quite obscure.
