Leaves ½–1¼ × ⅓–⅔ in., cordate or semiamplexicaul, deeply concave, glaucous, nerveless. Spikes 1–1½ in. long, dense. Calyx-segments obtuse, equalling the corolla-tube. Capsule oblong, obtuse, pubescent	42. V. amplexicaulis.
Leaves ¼–¾ × ⅙–½ in., obovate-oblong or suborbicular, deeply concave, glaucous, nerveless. Spikes short, dense. Calyx-segments obtuse, equalling the corolla-tube. Capsule oblong or obovate, obtuse, pubescent	43. V. pinguifolia.
Leaves ⅛–⅓ × ⅙–¼ in., broadly oblong or suborbicular, concave, nerveless, very coriaceous. Spikes short, dense, villous. Calyx-segments obtuse, exceeding the corollatube. Capsule oblong, obtuse, pubescent	44. V. Buchanani.
Leaves ⅛–⅓ in., obovate-oblong to lanceolate, usually lax, glaucous, obtusely keeled. Spikes ½–1 in., villous. Calyx-segments ovate, acute, exceeding the corolla-tube. Capsule ovate, acute, glabrous or pubescent	45. V. pimeleoides.
Section III. Small shrubs, erect or decumbent or prostrate. Leaves dimorphic; of mature plants small, short and thick, densely quadrifariously imbricated or rarely in distant pairs; of young plants larger, spreading, entire or irregularly lobulate or pinnatifid. Flowers crowded near the tips of the branches or in subterminal 2–4-flowered abbreviated spikes.
* Prostrate or decumbent, rarely erect. Flowers in 2–4-flowered abbreviated spikes near the ends of the branches and distinct from them.
Laxly branched, 3–12 in. long; branches ⅓ in. diam. Leaves ⅙–⅓ in., erecto-patent, linear-oblong, obtuse, margins strongly ciliate-denticulate	46. V. Gilliesiana.
Much and closely branched, 3–9 in. diam.; branches 1/12–1/10 in. diam., tetragonous with the faces concave. Leaves most densely quadrifarious, 1/14–1/10 in., ovate or narrow-deltoid, narrowed to a subacute point	47. V. tetrasticha.
Much and closely branched, 3–9 in. diam.; branches 1/15 in. broad, tetragonous with the faces flat. Leaves most densely quadrifarious, 1/18–1/16 in. long, broadly triangular, acute	48. V. quadrifaria.
** Erect or spreading or rarely decumbent. Flowers 3–8 near the ends of the branches, forming small terminal heads; bracts similar to the leaves or broader.
† Leaves densely imbricate with the opposite pairs connate and appressed, concealing the branch and giving it somewhat of the appearance of whipcord.
Prostrate, forming patches 6–18 in. across; branches 1/12–1/10 in. diam., obtusely tetragonous. Leaves densely quadrifarious, 1/15–1/12 in. long, broadly ovate-deltoid, obtuse, tumid	49. V. tumida.
Stout, erect; branches tetragonous, 1/10–1/6 in. diam. Leaves 1/12–1/10 in. long, deltoid-ovate, obtuse	50. V. tetragona.
Stout, erect; branches tetragonous, 1/10–1/6 diam. Leaves 1/12–1/10 in. long, broadly deltoid-ovate, suddenly narrowed into a short obtuse cusp	51. V. lycopodioides.
Stout, erect; branchlets terete or obscurely tetragonous, ⅛–⅙ in. diam., blackish-brown when dry. Leaves connate into a closely appressed ring 1/10 in. long, orbicular-oblong, obtuse	52. V. Hectori.
