well characterized by the tubular-funnelform corolla. In all other 

 characters it agrees well with the genus Eehites, 



Gonolobus calcicola, n. sp. Stems twining, ligneous at the base, 

 hii'tellous-puberulent, the younger parts also hirsute with spreading 

 or somewhat reflexed hairs : leaves petiolate, ovate, 2 to 6 cm. long, 

 1 to 3 cm. broad, acute or acuminate, entire, hirtellous-pubescent 

 above, granulosa beneatli and often scattered-hirsute especially on the 

 prominent midrib and nerves, revolute-margined ; petioles 10 to 22 

 mm. long, hirtellous-pubescent : inflorescence in axillary congested 

 several-flowered cymes ; peduncles shorter than the petioles : flowers 

 medium-size : calyx deeply o-parted ; divisions lance-elliptic, 6 to 7 mm. 

 long, 2 to 3 mm. broad, acute, ciliate, externally hirsutish pubescent : 

 corolla dark brownish-purple, about 2 cm. in diameter, externally min- 

 utely puberulent, upper or inner surface corrugated-verrucose, bearing 

 a few scattered whitish hairs : crown 5-lobed ; lobes fleshy, unequally 

 papillose or somewhat warty : fruit not seen. — Mexico. State of 

 Morelos : limestone hills, Jojutla, near Cuernavaca, 30 August, 1902,

In general habit G. calcicola suggests G. congestus, Decne., but the 

 smaller narrower leaves, fewer larger flowers, and the lobed crown serve 

 to separate readily the two species.

 viii. 282. Specimens belonging to this interesting variety have been 

 secured by Mr. E. W. Nelson at Montemorelos, State of Nuevo Leon, 

 no. 6697. Although the variety has been generally understood as 

 having merely sessile and amplexicaul leaves, yet the specimens now at 

 hand, from Mr. Nelson, show very distinctly that the leaves are not 

 only sessile and amplexicaul, but more or less decurrent on the stem. 

 Moreover a careful examination of Berlandier's uos. 699, 2116 (hb. 

 Gr.) show some of the leaves to be decurrent. The plant is a well- 

 •marked variety, and further material, especially complete specimens, may 

 prove it to be s.pecifically distinct. 



Cynoglossum Pringlei, n. sp. Stems leafy to the inflorescence, 

 striate, hirsute-pubescent : stem leaves ses.sile, semiamplexicaul, oblong- 

 lanceolate, 3 to 12 cm. long, 1 to 4 cm. broad, acute, entire, dark green 

 above, paler beneath, hii-sute-pubescent on both surfaces: inflorescence 

 compound, many-flowered, more or less bracteate: pedicels 0.5 to 2 cm. 

 long, recurved at least in the later stages, appressed-pubescent : calyx
