EASTWOOD. — MEXICAN SPECIES OF CASTILLEJA. 569 
recurvatis ; capsula elliptica acuta compressa 8 mm. longa. — Proc. 
Am. Acad. xxvi. 173 (1891). — Srate or Mexico: grassy slopes, Flor 
de Maria, 28 July, 1890, C. G. Pringle, no. 3194 (type, in hb. Gray), 
also from same locality, altitude 2440 m., no. 9429. To this species, 
at the time of its original description, was doubtfully referred a speci- 
men collected in Chihuahua by C. G. Pringle, no. 1545, which is below 
made the type of C. pediaca. In hb. U.S. Nat. Mus, sheet no. 396,150 
contains a specimen of C. macrostigma collected at the type locality 
by Rose & Hay, no. 6330, together with a specimen of C. Schaffneri. 
5. C. pediaca, n. sp., annua albo-pilosa et glandulare puberulens ; 
eaulibus prope basim recte ramosis, 2 dm. altis; foliis tenuibus lanceolato- 
acuminatis integris 3-5-nerviis, 2-3 cm. longis 1-2 mm. latis, basi 
amplexicaulibus 5-10 mm. latis ; floribus sessilibus interruptis acclini- 
bus ad axim spicae gracilis ; bracteis flores subaequantibus et investi- 
entibus, spatulatis 10-12 mm. longis, superiore parte flavo densissime 
glandulare puberulenti, apice truncato vel obtuso, inferiore parte pilosa 
nervia; calyce membranacea 12 mm. longo, fisso 6 mm., duobus partibus 
truncatis vel emarginatis 5 mm. latis ; corolla recta 18 mm. longa, galea 
acuminata apice glandulare pilosa, labio inferiore membranaceo non 
protuberanti, laciniis linearibus obtusis glandulare ciliatis 1.5 mm.longis, 
sinubus inter laciniis 1 mm. latis ; stigmate bilobo crasso, fere exserto ; 
Ovario subcylindrico ; capsula compressa oblonga 8 mm. longa 3 mm. 
iametro, apice acuminata; seminibus rhomboideis 1 mm. diametro, 
testa membranacea profunde foveolata. — Curauanva : plains, base of 
the Sierra Madre, 27 September, 1887, C. @. Pringle, no. 1545 (type, in 
hb. Gray), distributed as C. lithospermoides, var. (?) flava Watson ; 
also included under C. macrostigma Robinson in Proc. Amer. Acad. 
XXvi. 173 (1891). From this latter species it differs in having a more 
closely flowered spike, pilose instead of puberulent indumentum and less 
stigma. The flowers too are dissimilar, but the differences are 
not so obvious. It iseven further removed from C.- lithospermoides, being 
a slender-stemmed annual, while that is a robust perennial with some- 
what harsh pubescence. The slender spikes of C. pediaca have flowers 
about 1 cm. apart, somewhat distichous and appressed to an axis that 
is slightly tortuous, and are quite unlike the showy thickly flowered 
spikes of C. lithospermoi 
OS 6. C. sph aerostigma, n. sp., caulibus 1-2 simplicibus 1.5-2.5 dm. 
altis gracilibus adpressi-pubescentibus ; foliis integris vel pinnatisectis

margine frequente involutis, laciniis 2-6 anguste linearibus ; floribus
