DIDYMOCARPUS tacunosa. 
Native of Penang. 
Nat. Ord. Gesnzracem.—Tribe CrrTanpDRER. 
Genus Diprmocarrus, Wall; (Benth. et Hook. Sf. Gen. Pl. vol. iii, p. 1021.) 
Dipymocarrus (Heteroboea) lacunosa ; subacaulis, tomentosus, foliis confertis 
petiolatis oblongis v. ovato-cordatis crenulatis lacunosis, pedunculis 
elongatis 2-pluri-floris, bracteis lanceolatis pedicellis decurvis brevioribus, 
floribus secundis nutantibus, calyce 5-partito v. -fido segmentis lanceolatis 
corollz saturate violacee tubo pollicari postice medio gibboso-inflato, 
lobis brevibus late rotundatis recurvis integris, filamentis antherisque 
glaberrimis, ovario lineari pubescente in stylum mediocrum angustato, 
stigmate bifido. 
A lovely little plant, with intensely violet-blue nodding 
flowers, introduced by Messrs. Veitch from Penang, and of 
which Herbarium specimens were sent to the Royal 
Gardens in 1888 by Mr. Charles Curtis from damp rocks — 
near the coast, in the Island Langkawi, on the west side 
of the Malayan Peninsula, north of Penang. It is 
probable indeed that Messrs. Veitch’s plants were procured 
by Mr. Curtis at the latter locality, though shipped from 
Penang. 
The tribe Heteroboea of Clarke consists of eight (now 
nine) known species, all Malayan, and that to which D. 
lacunosa is perhaps most nearly allied is D. crinita, Jack, 
(Clarke in Fl. Brit. Ind., vol. iv. p. 351), figured at Plate 
4554 of this work, which is a native of Penang, Singapore, 
and the adjacent islands of Borneo and Sumatra ; it differs 
in being caulescent with a hirsute stem, longer leaves, and 
pale yellowish flowers with a much longer narrower tube. 
The native specimens of D. lacwnosa have a short very 
stout rootstock and longer petioles and leaves than the 
cultivated, and the old leaves and petioles and nerves 
beneath are more shaggy with rusty brown hairs; the 
flowers are identical. 
I am indebted to Messrs. Veitch for the loan of the 
specimen here figured, which was sent to Kew to be named 
in July of last year.—J. D. H. -
