DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 213 
DIDYMOCARPUS AREOLATUS, Stapf, n. sp. Caulis robustus, dense breviterque ferrugineo- 
tomentosus. Folia opposita, «equalia, petiolo 13 poll. longo breviter tomentoso 
suffulta, oblongo-elliptica, 8 poll. longa, 3 poll. lata, basi in petiolum breviter 
decurrentia, apice acuta, argute denticulata, supra nigricantia, in cost’ nervisque 
adpresse ferrugineo-hirtella, cæterum demum glabrata, tuberculis areolis polygonis 
graciliter circumscriptis crebre obsita, subtus breviter ferrugineo-tomentella, nervis 
lateralibus utrinque 16-17, graciliter, hine inde quidem distincte reticulata. Cymze 
in axillis sessiles ad fasciculos redactz, dense ferrugineo-tomentose ; bractew 
lineares vel filiformes, 1 lin. longe ; pedicelli 3—4 lin. longi. Calyx ad basin 
5-partitus; segmenta fere filiformia, sepe flexuosa, 4-5 lin. longa, tomentosa. 
Corolla alba; tubus basi angustus, deinde valde ampliatus, 10-12 lin. longus, extus 
fere glaber; labium superum 4 lin., inferum 6 lin. longum, hocce flavo-maculatum, 
lobis late rotundatis. Stamina fertilia filamentis applanatis genieulatis, antheris 
1 lin. longis, dorso glanduloso-pilosulis; sterilia lateralia circa 4 lin. longa, inter- 
medium duplo brevius. Ovarium basi disco majusculo circumdatum, anguste 
lineare, in stylum minute glandulose pilosulum abiens, cum eo 8-10 lin. longum; 
stigma bilobum. 
From 5000 to 7000 feet (Haviland, 1948). 
The leaves are very remarkable for their regular and graceful reticulation, which is 
finely impressed above, enclosing numerous hexagonal or pentagonal areoles with a 
tubercle in the centre. Underneath it is often inconspicuous on account of the tomentose 
covering, but it is generally very distinct in transparent light. The tubercle is the 
widened base of a hair, the upper and thinner part of which shrinks very soon and comes 
off. The corolla is in size and shape not unlike that of Chirita acuminata, R. Br., in 
which direction probably the affinity of the Kinabalu plant lies, though the calyx is 
divided to the very base and the segments are very narrow.
