numerous species in the series of slightly differentiated forms allied to 
Aeschynanthus volubilis Jack. A. Hoseana Kranzl. is perhaps the most 
closely alhed species, at least as to its general appearance. 
AESCHYNANTHUS LOHERI Kranzl. sp. nov. (§ Holocalyx), 
Caulis pars, quae adest, 20 cm tantum longa, radicibus per- 
paucis obsita, omnino glabra, internodia 1.5 cm ad 1.8 cm longa. 
Folia brevi-petiolata, ut plurimum 3 mm petiolis brevissime 
pilosis, laminae latissime oblongae, suborbiculares aut fere 
orbiculares, brevi-acutatae vel obtusae vel imo rotundatae, 2 ad 
3 cm longae, 2 ad 2.8 cm latae, superne et subtus glaberrimae, 
crassiusculae, inflorescentiae biflorae, pedunculus brevis, vix 1 
cm longus, bracteis 2 fere in cupulam connatis magnis latis 
obsitus, pedicelli 1.3 cm longi, brevissime pilosi, superne dilatati. 
Calyx amplus urceolaris, supra vix ampliatus, brevi-dentatus, 
dentibus brevi-triangulis, glaberrimus, 2.5 cm longus, basi 1 cm, 
in orificio 1.3 cm diam. Corolla levissime curvata, ampla, 5 cm 
longa, minutissime pilosa.et margine loborum ciliata, labium 
superius parvum, lobis 2 parvis rotundatis, labium inferius a 
superiore vix sejunctum, lobi laterales magni late oblongi, 
rotundati, lobus intermedius deflexus, antice retusus. Stamina 
corollam aequantia vel (longiora 2) illam excedentia. Discus 
bypogynus brevis integer, stylus curvulus minute pilosus. Fl. 
Januario.

Aeschynanthus Curtisii C. B. Clarke, of northern Borneo, is the only 
species to which A. Loheri can be compared, but in the former the flowers 
are much the larger, the calyx being 4.2 cm long and only 1 cm shorter 
than the corolla, while in the latter the corolla is twice the length of 
the calyx. 
AESCHYNANTHUS LEUCOTHAMNOS Kranzl. sp. nov, (§ Haplotrichium) . 
Caulis tenuis certe pendulus, radicibus multis tenuibus obsitus, 
albidus (unde nomen!), nitidus, cortice fragili passim sparsis- 
sime piloso vestitus, internodia 3 cm longa, pars quae adest 50 
cm longa, ubique eadem crassitie. Folia pro planta parva, brevi- 
petiolata, ovata, obtusa vel obtuse acutata, glabra, sicca livida 
(fere ut caulis), maxima 3 cm longa, 2 cm lata, apicem versus 
multo minora. Racemi 5- vel 6-flori, pedunculo brevi, floribus 
conglomeratis. Calyx rectus, urceolaris, glaber, margine tantum 
ciliatus, aeque 5-lobus, lobis late obtuseque triangulis, ad 4 cm 
longus, in orificio 1.8 cm diametro. Corolla paulum supra basim 
constricta, quam calyx multo angustior, levissime curvata, supra 
dilatata, labium superius rectum, profunde bilobum, lobis rotun- 
datis, labium inferius a superiore sinu amplo divisum, lobis
