MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



trichomes more persistent, the midril) and secondaries very 

 stron<j: and prominent, connected by a very fine and exceedingly 

 strong reticulation. 



Staminate panicles very slenderly branched, gray-puberu- 

 lent, the branches rather loosely flowered. Flowers 3 together in 

 a campanulate involucre with very shortly and unequally toothed 

 oblique margin and subtended by an ovate acuminate bract. 

 Flowers slenderly pedicelled, the pedicels pilose, about as long 

 as the involucre. Petals and sepals about equal, about 1 mm. 

 long, oval, obtuse. Stamens half the length of the petals. 



Pistillate panicles sparingly branched, the branches distant, 

 slender, gray-pubescent, densely flowered, the lower often sub- 

 tended by reduced leaves, the flowers green, sessile. Outer bract 

 ovate, the inner connate to form a sheath for the base of the 

 flower, densely pilose. Perigone puberulent within and without, 

 the sepals ovate, obtuse, with strong midrib and mostly 6-nerved, 

 in flower about twice the length of the obtuse, much narrower 

 and somewhat thinner petals. Stamens wholly absent. Pistil 

 two-thirds the length of the petals, the nearly sessile stigmas 

 flattened, at length spreading. Fruiting calyx 3 cm. long. Im- 

 mature fruit glabrous, 6-winged at the base, becoming 3-winged 

 in the upper third by the confluence of the lower wings in pairs, 

 the wings very acute.

Amaranthaceae 

 Gomphrena lutea 



Pilose, the slender white hairs mostly appressed, except about 

 the nodes. Stems or simple ascending branches mostly about 8 to 

 15 cm. long, slender, sulcate, sparsely leafy, the internodes long. 

 Heads terminal, about 1 cm. broad, yellow, closely subtended by 

 a pair of small leaves. Leaves sessile, 1.5 to 2.5 em. long, 4 to 6 

 mm. wide, lance-oblong, with narrowed base and acutely mucro- 

 nate summit, entire, pale-green, minutely punctate against the 

 light, the midril) stout, prominent beneath, the strongly ascend- 

 ing obscure secondaries about 3 on each side. Bracts hyaline 

 with strong green midrib, 2 or 3 mm. long, broadly ovate, acu- 

 minate and very acute. Bractlets 5 or 6 mm. long, hyaline below, 

 yelloAv above, long-acuminate and acute, slightly exceeding the 

 densely long-pilose sessile flower. Sepals narrow, nearly equal, 

 distinct to near the base, long-acuminate and acute, rigid. Sta- 

 men-tube a little shorter than the perigone, narrow, narrowed
