314 MR. SPENCER LE M. MOORE—PHANEROGAMIC BOTANY 
calyce circa duplo longioribus; calycis tubo ampliato, basi 10 superne 15-nervato, 
lobis ovato-lanceolatis tubo subeequilongis; floribus circa 1:2 cm. diam. ; carpidiis 
calvis, maxime depressis, ecarinatis, facile in valvulas duas dehiscentibus. 
Hab. Crescit prope Corumbá sine numero; fl. Jan. 
Suffrutex parvus, vix 4 met. alt. Radices albi, sparsim fibrosi. Caulis demum fere 
omnino glaber; pallide bruneus, juxta basin crebre longitudinaliter rimosus ; 
ramuli graciles, teretes. Folia 1:2-2'0 cm. long., medio 1:0-2'0 em. lat. ; stipulee 
puberule 0:35 cm. long; petioli ad 2:2 cm. long. (plerique vero breviores), graciles, 
pilosi-tomentosi. Pedunculi ad 39:5 cm. long. (plerumque circa 3:0 cm.), graciles, 
supra medium articulati, pilosi-tomentosi. Involucri phylla circa 1:0 cm. long., 
filiformia. Calycis piloso-tomentosi tubus 0°3 em. long.; lobi 0'4 cm. long., 3-nervati. 
Flores lutei. Carpidia 0:4 cm. long. et 0:4 cm. lat., venosa (nervo medio parum 
eminente), in sieco virentia. Semina obconica, vix 0:3 em. diam., glabra. 
Affinis Pavonie Balanse, Guerke, et P. Hieronymi, Guerke, sed multis notis ab 
ambabus dispar. 
The easy splitting of the carpidia, seen also in the case of P. Balanse, is curious, and 
might perhaps justify the creation of a new genus. The greatly depressed form of the 
same organs is also unlike what we usually find among the Pavonias. [Paraguaria.]

, Var. HEXAPHYLLA, S. Moore. A typo discrepans vestitu pilorum patentium, habitu 
gracili, pedunculis tenuibus, involucri phyllis plerumque 6, raro 7, angustis (0:05 em. 
lat.), sed vix, me judice, species propria. 
Hab. Crescit ad ripam fl. Paraguay, prope Barra do Sáo Lorenzo. (N. 10.) 
Hujus varietatis exstant forme due, foliis alterius subtus canescenti-tomentosis, 
alterius canescenti-pubescentibus, dein pubescentibus. Hæc involucri phyllis brevibus 
calycem vix excedentibus gaudet, illius involucri phylla contra calyce duplo longiora.

Hab. Crescit in cacumine montium Serra da Chapada, mens. Aug. florens. (N. 181.) 
[ Bras. Or.] 
PAVONIA OPULIFOLIA (sp. nov.); caule erecto, subtereti, stellatim tomentoso, mox 
appresse pubescente ; foliis petiolatis, late cordatis, 3—5-lobatis (plerumque 3-lobatis), 
impariter grosse crenato-serratis, 7—9-nerviis, sparsim stellatim pubescentibus et ad 
nervos tomentosis ; stipulis lanceolatis ovato-lanceolatisve, quam petioli brevioribus ; 
floribus in axillis fol. superiorum solitariis; pedunculis quam petioli longioribus; 
involucri phyllis 13-14, calyci subzequilongis ; calycis lobis lanceolatis, tubo 
longioribus ; corollá vix 2:0 cm. diam. ; tubo stamineo 0*6 cm. long.; stylis obscure 
puberulis; carpidiis calvis, medio dorso leviter carinatis. 
Hab. Inveni mens. Aug. ad ripas fl. Cuyabá vigentem, loco longinquo ab urbe Cuyabá 
iter duorum dierum. (N.3.)
