ellipsoid, 4 by 3 in., smooth, crowned by the conical disk, which is girt at its base by 
the very short calyx-limb.—Kurz distinguishes the Andaman form as var. puberuia, 
with the petioles, stipules, nerves beneath, pubescent.

81. HYDNOPHYTUM, Jack. 
Epiphytic glabrous shrubs, with a deformed fleshy tuberous simple or lobed 
stock, excavated by ants; branches square. Leaves opposite, leathery, obtuse ; 
stipules interpetiolar, deciduous. Flowers small, axillary, solitary or fascicled, 
sessile, white.  Calya-tube ovoid, limb obscure. Corolla funnel- or salver- 
shaped, tube long or short; lobes 4, short, valvate. -Anthers 4, subsessile on 
the corolla-throat, oblong. Ovary 2-celled ; style-arms narrow or broad ; ovules

Tuberous stock 6-14 in., smooth, rooting from its under surface; branches few, 
simple, or sparingly divided, stout. Leaves 3-4 by 1-2 in., pale brown when dry, 
coriaceous, nerves obscure, narrowed into the very short stout petiole. Flowers few. 
Corolla-tube 35 in., glabrous without; lobes oblong, acute. Fruit oblong, crowned by 
the crateriform calyx-limb, smooth, glossy, orange-crimson.—The specimens I have 
seen are very insufficient as to flowers and fruit, the characters of which are in part 
borrowed from Kurz.

Sixcaronz, A, Wallace.—Distris. Malay Archipelago, N. Australia? 
This is a very little known plant, of which my only materials are tubers and seeds 
sent by Mr. Wallace in 1855, with an excellent. sketch containing some analyses. The 
sketch represents a nearly globose tuber, 2} in. diam., excavated by ants, depressed at 
the top, irregularly grooved, studded with spinules irregularly disposed in longitudinal 
lines. Short thick simple curved branches, 4-6 in., proceed from a very short stock 
on the crown of the tuber; these are covered throughout their length with ovoid
