20 BOTANY OF THE VOYAGE OF THE SULPHUR. 
internodiis sepius breviora, carnosula, vix semilineam lata, pleraque abrupte in mucronem brevem acutata. 
Stipule minima, integre: aut 2-3-fidee, seepe vix conspicue. Cyme dichotoma, foliose, laxee vel congeste. 
Pedicelli seepius brevissimi, rarius 1-2 lin. longi. Calycis tubus usque ad apicem ovarii adnatus, limbi laciniz 
lanceolate, foliacese, acutissimee. Corolla infundibuliformis, calyce duplo longior, intus glabra. Filamenta 
brevia. Antherz oblongo-lineares. Styli lobi oblongi. Ovarii loculi oligospermi. 
This plant has something of the habit of the Cape T’hesia, and it is evidently 
allied to some of the Peruvian species of Ericotis. The flowers in the specimens 
before me are most of them too much deformed, apparently by the effect of some 
insect, to admit of any very accurate description. 
65. Mirracarrium lineare, sp. n., annuum, erectum, glabriusculum, foliis linearibus, calycis 
laciniis 2 majoribus corolle tubo subdimidio brevioribus, 2 multo minoribus.—Cape San Lucas. 
Herba pusilla, parum ramosa, 4-6-pollicaris. Caulis tetragonus, pube minuta scabriusculus vel demum 
glaber. Folia flavescenti-viridia, crassiuscula, margine recurva, obscure uninervia, majora pollicaria. Stipule 
glabree, vagina albida 1 lin. longa, setis utrinque 3-5 inequalibus, intermediis vaginee equilongis, lateralibus 
brevioribus. Capitula seepius ad apices ramulorum solitaria, majuscula, foliis floralibus quatuor caulinis 
similibus. Calyx glaber vel minute ciliato-puberulus, laciniis 2 lanceolato-linearibus acutis viridibus, 2 parvis 
hyalinis. Corolle tubus 13 lin. longus, glaber, laciniee limbi ovate, acute, tubo dimidio breviores. Calyx

66. Pectis multiseta, sp. n., caule diffuso ramosissimo puberulo, foliis lanceolato-linearibus 
acuminato-piliferis per totam longitudinem dentibus aristatis ciliatis, crebre glanduloso-punctatis, 
pedunculis folia superantibus ebracteatis monocephalis, involucri squamis 5 late lineari-oblongis 
carinatis, pappo radii 2-3-setoso, disci coroniformi unisetoso vel mutico.—Cape San Lucas. 
Herba annua, pedalis. Rami flexuoso-diffusi, oppositi, graciles, pube minutissima albida conspersi. 
Folia pleraque pollicaria, basi angustata, margine subrecurva, utroque latere denticulis piliferis 6-8 subeequidis- 
tantibus notata, supra viridia, subtus pallida. Glandule plurime majuscule, sparse, in pagina inferiore promi- 
nul, alice numerosee minores immerse, omnes pellucide. Pedunculi solitarii, terminales, floridi ramulos 
superant ; demum ramulis elongatis in dichotomiis persistunt, basi foliorum paribus 2-3 approximatis suffulti. 
Involucrum 2 lin. longum, insigniter 5-costatum, minute puberulum. Squame inter se leviter cohzrentes, 
apice breviter liberee, acutiuscule. Corolle radii 5, squamis involucri opposite et arcte appressze, ligulis luteis 
patentibus integris acutis 2 lin. longis. Corolle disci fere 20, tubulosee, ligulis breviores, ex sicco lute, dentibus 
Janceolatis obscure bilabiatis. Achenia linearia, teretia, minute appresso-puberula, pappo coroniformi 
brevissimo.  Aristee rigidee, pilis brevibus paucis obverse ciliatee, achenio breviores, in radio sepissime tres 
parum ineequales divergentes, in disci acheeniis exterioribus solitarie, in interioribus nulle. 
67. Hetocyne fasciculata, gen. nov. (Plate XIV.)—Bay of Magdalena. 
: Cuar. GEN. Capitulum multiflorum, homogamum. Inyolucram imbricatum squamis line- 
aribus acutissimis numerosis. Receptaculum planum, nudum. Flores hermaphroditi tenuissime 
tubulosi, 5-dentati. Pappi pales 2-3 breves hyaline sublacere et ariste 2-3 scabride corollam 
superantes.—Genus e tribu Eupatoriacearum Ageratearum.
