“flowers shut after noon,” J. Reverchon, no. 2759, with seeds (hb. 
Mo. Bot. Gard., hb. U. S. Nat. Mus.); Pine Island, Angelina, J. 
Reverchon, no. 2780, without seeds (hb. Mo. Bot. Gard.). 
As shown by the herbarium sheets this plant has sometimes been 
distributed as H. juncea Smith. Although rarely it tends to approach 
H. juncea in habit, generally it has a dense tuft of coarse fibers at the 
base and wider leaves. It has also been distributed as H. decumbens 
L., but superficially it differs from H. decumbens in having a stiff tuft 
of bristles at the base, while the leaves of H. decumbens do not dis- 
integrate into fibers. Most often it has been distributed as H. 
hirsuta (L.) Coville. "The bristly base and the coarser texture of the 
leaves should superficially distinguish it from H. hirsuta. The seeds 
clearly separate it from each of the above mentioned species. 
5. H. tepicensis, n. sp., cormo ellipsoideo 9 mm. crasso vaginis 
scariosis fibrillosis pallide brunneis investo; foliis linearibus subrigidis 
3-6 mm. latis 0.6—4 dm. longis sparse pilosis; pedunculis sparse 
pilosis vel glabratis 0.4-3 dm. longis; pedicellis arcuatis 2-5 cm. 
longis; ovario capsulaque pilosis; segmentis perianthii lanceolatis 
subacutis 7-10 mm. longis extus viridibus; capsulis ellipsoideis 4-8 
mm. longis; seminibus 0.7-1.3 mm. diametro atris densissime papillo- 
sis, papillis valde elongatis obtusis. 
Corm ellipsoidal, 9 mm. thick, covered with scarious, fibrillous, 
light brown sheaths; leaves linear, rather rigid, 3-6 mm. broad, 
0.64 dm. long, sparsely pilose; peduncles sparsely pilose or becoming 
glabrate, 0.4-3 dm. long; pedicels curving, 2-5 cm. long; ovary and 
capsule pilose: perianth-segments lanceolate, rather acute, 7-10 mm. 
long, green outside: capsule ellipsoidal, 4-8 mm. long; seeds 0.7-1.3 
mm. in diameter, black, very densely papillose; the papillae strongly 
elongated and obtuse.—In western Mexico. The following are 
referred here. Terc: Pedro Paulo, J. N. Rose, no. 3319, as the TYPE 
of this species, with seeds (hb. U. S. Nat. Mus.); between Pedro 
Paulo and San Blascito, J. N. Rose, no. 3307, with seeds (hb. U. S. 
Nat. Mus.). 
6. H. sEssrLIS L. Corm cylindric to slenderly ovoid, 0.5-1 cm. 
thick, covered with membranous but scarcely fibrillous brown sheaths; 
leaves linear, 1-4 mm. broad, 0.7-3 dm. long, firm; peduncles essenti- 
ally wanting or up to 8 cm. long, filiform, pilose; ovary and capsule 
densely pilose; perianth-segments lanceolate, rather acute, 7-19 mm. 
long; capsule pyriform, 3-4 mm. long; seeds black, ellipsoid, 1—4 
mm. in diameter; the low, flat pebbling almost completely covered 
with a closely granular film or coating of a golden-brown iridescent 
material; the short beak and rostrate hilum black.—Sp. Pl. ed. 2.
