Description
PLATE XXVIII Marina scopa Barneby, a coarse monopodial annual flowering in late fall and winter, colonial in cornfields, disturbed places, pedregal, and along highways over much of temperate and arid tropical Mexico and central America, sparingly adventive in Venezuela and Cuba. The plant is wholly glabrous, with one stout, red, virgate stem often a meter tall or more that loses its frondose foliage in the dry season as it passes upward into an elaborately ramified, fastigiate or amply flat-topped panicle of capillary, few-flowered racemes. Only one flower in each raceme is open at a time. The petals are expanded at dawn and early caducous, falling readily if the stems are shaken and naturally deciduous by noon. The related M. nutans (Plate No. XXIII), often confused with M. scopa, has many flowers open at once, is perennial, and has a differently shaped banner. Inflorescence and main cauline leaf × 1; the rest × 5. 1) branchlet from panicle; 2) main cauline leaf; 3) flower, in profile; 3a) another flower; 3b) flower, dorsal view; 4) banner, 2 ventral 1 profile view; 5) wing; 6) keel; 7) androecium, expanded and coiled after anthesis; 8) pod.
