usually margined : racemes axillary or in a terminal panicle, sessile, 

 short (1 or 2, sometimes in fruit 3 or 4, inches long), the pedicels 



1 or 2 (becoming 3) lines long: sepals yellowish white, cordate at 

 base, 3 narrowly ovate and acutish, 2 oblong and obtuse, at length 

 greenish, shorter than the fruit (5 lines long) and scarcely enclosing 

 it: anthers reddish brown. Chapala, among hills. (722.) — Differ- 

 ing from the various forms of A. leptopiis in the color of the sepals, 

 which are also in fruit much narrower and shorter. 



Akistolochia (Gymnolobus) longecaudata. Finely pubescent 

 throughout; stems herbaceous from a stout elongated root, trailing: 

 leaves oblong-hastate, acute, with a deep sinus between the rounded 

 basal lobes, 1 to H inches long; petioles J inch long or less: pedun- 

 cles axillary, 1 to 3 lines long, with a sessile cordate-lanceolate bract: 

 ovary linear, 3 lines long : calyx pubescent, slightly dilated for 4 lines 

 below the broad nearly straight half-longer upper portion of the tube 

 (partially closed at base by a glabrous funnelform diaphragm), en- 

 larging upward, and terminated by a long-attenuate lamina (2 inches 

 long) : stamens 5 : lobes of the style attenuate and pubescent above : 

 capsule oblong, an inch long, attenuate at base. Guadalajara, in 

 moist bottoms; August. (278.) — Near A. hmgijlora and A. bre- 

 vipes. Lamina dark brown with a baud of yellow at base dotted 

 with black. 



Akistolochia Palmeri. Of the same section, somewhat puberu- 

 lent or finely pubescent throughout, the several span-long stems erect 

 from a fusiform root : leaves linear-hastate, long-acuminate, 2 or 3 

 inches long, truncate at base, the narrow divaricate lobes obtuse ; peti- 

 oles 4 to G lines long : flowers axillary, nearly sessile, the bract linear- 

 lanceolate ; ovary linear, 2 lines long: dilated base of the calyx 4 lines 

 long, the slightly curved tube (8 lines long) dilated above, with a 

 lanceolate very long-attenuate blade (3 inches long and 5 lines broad 

 at base) yellowish down the middle and thickly dotted with purplish 

 brown ; diaphragm at base of the tube funnelform, glabrous : stamens 

 5 : stigma cup-shaped, cleft to the middle, the acuminate lobes incurved : 

 capsule broadly ellipsoidal, 8 lines long, shortly stipitate. Rio Blanco, 

 among grass near streams ; July. (180.) 



Aristolociiia Tequilana. Of the same section : stems long, her- 

 baceous, trailing, villous, as also the petioles and peduncles : leaves 

 cordate, acute, with a rather deep sinus and rounded basal lobes, wilh 

 scattered short appressed hairs above and hispid on the veins beneath, 



2 or 2^ inches long; petioles 8 or 10 lines long: peduncles axillary, 

 i inch long; bract small, cordate: ovary villous, clavate : calyx with
