plants which flowered .in the nursery of Mr. Herb of 
Naples represent peduncles about as long as the petioles, 
though in the text the flowers are described as being 
long-stalked. The peduncles in the Kew plants were 
three to fourincheslong. This is probab!y due to indoor 
cultivation. Mr. A. Purpus recommends the plant for 
sunny, dry places. Protected from wet, the tuberous 
rootstocks survived the winter out of doors at Darmstadt. 
The species is described a3 non-climbing. At Kew the 
stems have reached a length of about 3 ft. and do not 
show the tendency to climb by means of the petioles met 
with in most Maurandias; J/. Purpusii differs markedly 
in this respect from its close ally, IM. erubescens. Only 
one species, MZ. erecta, Hemsl., so far as is known, has a 
distinctly erect self-supporting stem. The genus Mau- 
randia comprises eight species (or seven if I. geniculata, 
Robinson & Fernald, be referred to Jf. erecta, which it 
resembles very closely) all of which are natives of Mexico, 
one, M. Wislizenii, Engelm., extending to New Mexico. 
M. erubescens and M. semperflorens, Ort., have become 
naturalised in some of the West Indian Islands and in 
some parts of Tropical America. These two species and 
M. scandens, A. Gr., are figured in this Magazine at 
tt. 460, 3037, 3038 and 3650. 
_ Descriprion.—Herb, perennial, shortly glandular-pubescent; base of stem 
and roots thick and fleshy. Stem slender, ascending or prostrate, hardly 
scandent, 3-4 ft. long. Leaves alternate, petioled, wide triangular-ovate, 
acute, base deep-cordate, irregularly toothed or crenate, at times nearly entire, 
13-1} in. long, 13-2 in. wide at the base; petiole 1}-1% in. long. Flowers 
showy, long-stalked, solitary in the upper axils; peduncles ascending, slender, 
in. long, usually longer than the leaves. Calyx herbaceous, 5-partite 
almost to the base; lobes oblong-ovate, rather rounded and apiculate, base 
cordate, about 2 in. long, } in. wide. Corolla bright rose-purple, 14-1} in. 
long, almost glabrous externally ; tube narrow-funnel-shaped, slightly swollen 
at the base in front, glandular-pubescent within, especially at the base; limb 
patent, 2-lipped, almost equally 5-lobed, about 1 in. across ; lobes suborbicular, 
about } in. wide. Stamens 4, in two pairs, hardly exserted ; filaments densely 
glandular-pubescent. Ovary conical, glandular-pubescent like the style which 
is shorter than the stamens and is entire at the tip. Capsule ellipsoid, rounded 
above, unequal at the base, about } in. wide, rather shorter than the calyx, 
tipped by the persistent style. Seed almost orbicular, about + in. wide, tuber- 
culate, with a surrounding emarginate, striate, toothed or sinuate wing.
