oP Petrocosmea Henryi, Craib, a P. minore, Hemsl., antheris 
elongatis inter alia facillime distinguenda. 
Herba acaulis, rhizomate brevi crasso radices numerosas 
emittente. Folia rosulata, saepissime ovata vel obovata, 
rarius fere orbicularia, apice obtusa rotundatave, basi plerumque 
parte triente inferiore cuneata, ad 2 cm. longa et 1.5 cm. lata, 
chartacea vel membranaceo-chartacea, supra pilis albis flaccidis 
transverse septatis sicco plus minusve adpressis instructa, 
subtus sericea, nervis lateralibus utrinque 3-5 supra obscuris 
subtus subconspicuis, nervulis omnino obscuris, margine crasse 
plus minusve regulariter paucidentata, dentibus satis distantibus 
plerumque apice rotundatis, longius albo-ciliata ; petioli usque 
cm. longi, albo-pilosi, pilis mox inferne plus minusve 
brunnescentibus. Pedunculi (forsan haud semper) uniflori, 
circa 4.5 cm. longi, albo-pilosi, 6-10 mm. infra apicem bibracteo- 
lati. Calyx intra glaber, extra dense albo-pilosus, subaequaliter 
5-fidus, segmentis circa 2.5 mm. longis et 0.75 mm. latis calloso- 
apiculatis. Corolla extra lobo mediano labii antici et labio 
postico marginem versus exceptis pilis transverse septatis saepe 
capitatis albo-pilosa ; tubus vix 2 mm. longus; labium posti- 
cum ovato-deltoideum, apice emarginatum vel retusum, 5.5 mm. 
longum, 6.5 mm. latum, anticum 9 mm. longum, Io mm. latum, 
3-lobatum, lobis inter se aequalibus oblongis apice rotundatis 
vel truncato-rotundatis vix 5 mm. longis 3.75 mm. latis cum 
labio postico margine pilis transverse septatis capitatis longius- 
culis ciliatis. Antherae duae anticae fere 5 mm. longae, basi 
sagittatae, conniventes, filamentis ima basi corollae tubi insertis 
3 mm. longis complanatis apicem versus gradatim paulo angus- 
tatis circa I mm. supra antherarum bases affixis glabris ; 
staminodia 3, duobus 1.5 mm. longis, postico aliis multo breviore, 
omnibus linearibus glabris. Ovarium subsericeum, I.5 mm. 
altum, stylo 8 mm. longo superne glabro basem versus adpresse

scriptione et planta Hancockiana exclusis.

Examination of Hancock’s specimens proves that the figure 
in Hooker’s Icones of P. minor was drawn from these plants 
and not from Henry’s collections. As pointed out above, the 
two plants may be very readily distinguished by the shape of 
their anthers, those of P. minor proper being as figured short 
and elliptic, whereas those of Henry’s plant are elongate and
