out, once to once and a half length of spore, with one whorl of rather large, much-branched 

 appendages, near the base.

Tecoma Leucoxylon (I,.) Mart. {T. hahamensis Northrop), Bahamas. 

 Type locality : New Providence, Bahamas, on Tecoma hahamensis. 

 Distribution : Known only from the type locality. 



15. NEPHLYCTIS Arth. Jour. Myc. 13: 31. 1907. 



Cycle of development includes only pycnia and telia, both subcuticular, 

 Pycnia hemispherical ; hymenium flat ; ostiolar filaments wanting. 

 Telia erumpent, somewhat indefinite, without paraphyses. Teliospores free, two-celled 

 by transverse septum, verrucose, the cells similar in shape and size ; wall indistinctly lami- 

 nate, colored, gelatinous layer obscure, the pores one in each cell, apical in upper cell, near 

 the pedicel in lower cell ; pedicels usually unappendaged. 



Types species, Puccinia elegans Schrot. (on Tecoma Stans). 



Teliospores slightly constricted, inconspicuously verrucose. 1. N. iransformans . 



Teliospores strongly constricted, prominently verrucose. 2. N. conjuncta.

Puccinia transformans Ellis & Ev. Erythea 5 : 6. 1897. 



Puccinia exitiosa Sydow & Holway ; Sydow, Monog. Ured. 1 : 245. 1902. 



O. Pycnia amphigenous and caulicolous, 3-15 in orbicular groups, punctiform, cinna- 

 mon-brown, conspicuous, hemispherical or conoidal, 110-145 /^ broad, 50-90 /i high; pycnio- 

 spores very numerous above a fiat hymenium. 



III. Telia amphigenous, caulicolous, and fructicolous, causing hypertrophy, on leaves 

 roundish, 0.1-0.5 cm. across, on stems and pods confluent over swellings 1-3 cm. long and 

 nearly as broad and thick, soon naked, cinnamon-brown, very pulverulent, ruptured cuticle 

 noticeable; teliospores ellipsoid, 16-22 by 27-35 j", rounded at both ends, slightly constricted 

 at the septum; wall cinnamon -brown, thick, 2-3.5//, slightly thicker at the apex, 3-5//, by 

 a paler umbo, gelatinous layer scarcely perceptible, sparsely and finely verrucose ; pedicel 

 colorless, short, half length of spore or less, fragile.

2. Nephlyctis conjuncta (Dietel & Holway) Arthur. 



Puccinia conjuncta Dietel & Holway; Holway, Hot. Gaz. 31 : 335. 1901. 



O. Pycnia chiefly epiphyllous, crowded on small brownish spots 0.5-2 mm. across, in- 

 conspicuous, subcuticular, hemispherical, 140-160 /^ broad by about half as high ; hymenium 



flat or nearly so. 



III. Telia amphigenous, usually surrounding pycnia, few, crowded in orbicular groups 



1-2.5 mm. across, often confluent, sometimes on stems in large masses, soon naked, dark 

 cinnamon-brown, at first pulvinate, becoming pulverulent, ruptured cuticle barely notice- 

 able ; teliospores ellipsoid, 23-26 by 35-42 /£, rounded at both ends, strongly constricted at 

 the septum forming two globular and nearly equal cells ; wall dark cinnamon-brown, moder- 

 ately thick, 2-2.5 /i, with apex slightly thicker, 3-6/^, in part formed by the hyaline cover- 

 ing of the pore, sparsely and strongly verrucose with conoidal beads ; pedicel colorless, 

 short, fragile, breaking off near the spore. 



On Verbenaceae :
