FLORA. 



the inner often connate above the 2-celled, 2-3-ovuled ovary ; style cleft into 

 2 or 3 entire or 2-cleft stigmas. Fruit a 2-3-celled, 2-3-beedcd capsule, loculici- 

 dally dehiscent. [Name in honor vlDnpaty.} About 215 species, mostly natives of 

 tropical America. Only the following is known in the U. S. : 



I. Dupatya flavidula (Michx.) Kuntze. DUPATYA. (I. F. f. 902.) Leaves 

 3-5 -nerved, 2-5 cm. long, awl-shaped, woolly at the base, glabrous or sparingly 

 pubescent above. Scapes usually numerous, 5 -angled, pubescent, 1-3 dm. high ; 

 sheaths longer than the leaves, slightly inflated above, pubescent ; involucral 

 bracts straw-colored, glabrous, obtuse, oval, shining, somewhat pubescent at the base; 

 scales very thin, scarious-white, linear, slightly pubescent, about as long as the 

 flowers ; flowers about 2.5 mm. high ; perianth 6-parted ; outer perianth of the 

 staminate flowers stalked, woolly, the inner a campanulate tube with 3 stamens ; 

 pistillate flowers with both sets of perianth-segments distinct, the inner much 

 narrower than the outer ; style 3 -parted ; stigmas 3. In moist pine barrens, 

 S. Va. to Fla. March-July. 



3. LACHNOCAULON Kunth. 



Tufted herbs with the habit of Eriocaulon, the leaves linear. Scape several- 

 angled, sheathed at the base by an entire bract about as long as the leaves ; heads 

 globose. Receptacle pilose. Flowers androgynous. Perianth of 3 segments. 

 Staminate flowers with 3 stamens united below into a thickened tube which is coa- 

 lescent with a body, variously regarded as a corolla or as a rudimentary pistil, 

 bearing at its apex 3 fimbriate or entire lobes alternate with the filaments ; 

 anthers i -celled, minute. Pistillate flowers with a sessile 3-celled, 3-ovuled ovary 

 surrounded by copious woolly hairs at the base ; styles united below, spreading 

 above into 3 divisions which are 2-parted, there being thus 6 stigmas. [Greek, 

 referring to the woolly scapes of some species.] Four known species, natives of 

 the southern U. S. 



I. Lachnocaulon anceps (Walt.) Morong. HAIRY PIPEWORT. (I. F. f. 

 903). Leaves glabrous or sparingly pubescent, 2-8 cm. long, tapering to an 

 obtuse callous tip. Scapes slender, 0.5-5 dm. tau *> 2-4-angled, clothed with long 

 soft appressed upwardly pointed hairs ; sheaths equalling or shorter than the 

 leaves ; heads globose, 26 mm. in diameter ; involucral bracts ovate or oblong, 

 shorter than the flowers, usually brown ; flowers about 2 mm. high ; scales brown, 

 spatulate, white-bearded at the apex ; perianth of the staminate flowers short- 

 stalked, pubescent at the base, woolly and fimbriate at the summit ; segments of 

 the pistillate perianth white, glabrous, obtuse ; ovary densely villous around the 

 base ; seeds strongly ribbed. In most pine barrens, Va. to Fla. March-June. 



Family 4. BROMELIACEAE J. St. Hil. 



Pine- Apple Family. 



Epiphytic herbs (some tropical species terrestrial), mostly scurfy, with 

 elongated, entire or spinulose-serrate leaves. Flowers spiked, panicled, 

 or solitary, regular and perfect, usually conspicuously bracted. Perianth 

 of 3 thin distinct or somewhat united sepals, and 3 clawed distinct or 

 united petals. Stamens 6, usually inserted on the base of the corolla. 

 Ovary inferior or superior, 3-celled ; ovules numerous in each cavity, 

 anatropous ; style short or elongated ; stigmas 3. Capsule 3-valved in 

 our species. Seeds numerous, the testa membranous. Embryo small, 

 situated at the base of the copious endosperm. About 35 genera and 900 

 species, all natives of tropical and subtropical America. 



i. TILLANDSIA L. 



Epiphytic plants with narrow entire leaves and white, yellow or purple flowers. 

 Sepals distinct and separate or very nearly so. Petals distinct. Stamens hypo- 

 gynous or the three inner ones inserted on the bases of the petals; filaments filiform; 

 anthers linear or linear-oblong. Ovary superior ; style subulate ; stigmas short. 

 Capsule septicidally 3-valved. Seeds erect, narrow, supported on a long funiculus 

 which splits up into fine threads. [Dedicated to Elias Tillands, Swedish (?) botanist
