closely in aspect to Chirita as well as to Didymocarpus. The 
increase of the number of perfect stamens is a character not very 
much more secure in this order than the form of stigma. I have 
little doubt that Didymocarpus will ultimately be split up, and 
in that case Roettlera would be a fitting generic name for the 
present section Orthobaea, as suggested by Bentham and Hooker 
(Gen. Plant., 11. 1022). 
Didymocarpus Burkei, W. W. Smith. Sp. nov. Plate ciil. 
Species Didymocarpo leucocalyci, C. B. Clarke affinis sed inter 
species Eudidymocarporum foliis pulchre et mire pilosis distincta. 
Herba erecta, circ. 30 cm. alta, habitu et magnitudine D. 
leucocalyci similis. Caulis dense fulvo-pilosulus. Folia basalia 
desunt ; folia caulina opposita, 2-3 paria, inaequalia, ad 15 cm. 
longa, ad 8 cm. lata, petiolis plus minusve 3 cm. longis fulvo- 
pilosulis, elliptica vel ovato-elliptica, apice obtusa, basi breviter 
inaequaliterque cordata vel cuneata, serrata, supra dense pilosula, 
pilis miro modo in nodulos aggregatis, infra uniformiter pilosula ; 
nervi utrinque 6-8 supra immersi, infra distinctiores. Inflor- 
escentiae cymosae multiflorae longe pedunculatae 3-4 ad apicem 
caulis aggregatae, foliis paululum longiores; pedunculi circ. 
rocm. longi, subrigidi glabri rubri, ad apicem iterum atque iterum 
divisi; pedicelli 5-10 mm.longi graciles; bracteae ad 3 mm.longae, 
suborbiculares vel oblongae. Calyx 2-3 mm. longus, 2 mm. latus, 
glaber, fere ad imum in lobos quinque ellipticos obtusos fissus. 
Corolla circ. 12 mm. longa, glabra, in sicco purpurea ; tubus 
cylindricus 1 cm. longus, 1°5 mm. latus, superne paululum 
ampliatus ; lobi valde inaequales rotundati. Stamina inclusa, 
duo perfecta, filamentis pubescentibus antheris cohaerentibus ; 
staminodia duo minima vel saepe absentia. Ovarium lineare 
breviter stipitatum disco brevi cylindrico. Fructus immaturus 
1°5 cm. longus linearis, D. leucocalycis ei similis.
