appear on the stems opposite the leaves, and carry 4 or § large and beautiful but 
drooping flowers. Sepals and petals are rosy-mauve, the petals being nearly twice 
as wide as the sepals. The flowers, being flattened, give the appearance of being 
only partly opened. The labellum is nearly 24 inches long, tongue-shaped, pale 
lavender (sometimes almost white) striped and spotted with intense purple with 
a blotch of deep maroon in the centre. A3. B1. C3. D1. E2. (ed) Fl. 
DENDROBIUM MACFARLANEI. 
A Synonym of Dend. Johnsoniae. 
DENDROBIUM MACGREGORI. Native of Louisiade Islands. 
A distinctive species with very numerous thick roots and stems growing from a 
twisting rhizome. ‘These stems are slightly swollen at the base and are then fusi- 
form, the upper part being terete. They grow to a height of 8 or 9 inches, and 
have a few oblong-lanceolate bilobed leaves. Racemes come from the top of the 
stems and carry 2-4 good-sized flowers (about 2 inches across). 
The sepals are white, spotted with purple, while the petals are white, spotted with 
pale gold. The labellum, which has large, erect, triangular, lateral lobes and a 
kidney-shaped middle lobe, has the latter bright yellow ornamented with violet lines 
while the laterals are white, spotted with violet. A2. B2. C1. D2. El. (ea) F4. 
DENDROBIUM MACRANTHUM. Native of Queen Charlotte Island, New 
Hebrides, and Samoa. 
This species (which should not be confused with Dend. superbum, which has as 
one of its synonyms D. macranthum (Hook) ) has smooth stems about 2 feet high, 
terete and articulated, clothed with elliptic leaves, slightly bilobed at the apex, 
about 14 inches. Racemes about a foot in length, carrying from 6 to 9 flowers. 
These have erect dorsal sepal and petals, narrow and pointed, and somewhat 
twisted, the lateral sepals being falcate, deflexed, pointed and semi-twisted. The 
labellum has semi-ovate lateral lobes, the middle lobe being oblong-lanceolate with 
an undulated margin, and having three elevated lines on the disk. The flowers 
are true white, and nearly three inches across. Al. B2. Cl. Dl. El. (ea) FI. 
DENDROBIUM MACROPHYLLUM. Native of New Guinea, Java, Timor, etc. 
A curious species with club-shaped, rather slender, jointed and deeply furrowed 
and somewhat flattened stems, about 12 inches high and carrying at the top a few 
oblong, acute, irregularly bilobed, thick, fleshy leaves up to about 15 inches in 
length and 24 inches across. These stay on the stems for 2 or 3 years. Racemes 
about 8 to 12 inches in length, grow from the apex and carry a number of quaint, 
but hardly beautiful flowers which are somewhat inclined to nod. Sepals are 
greenish yellow, while the petals are whitish. The labellum has somewhat kidney- 
shaped lateral lobes, the front lobe being dilated and spreading. It is greenish in 
colour, the side lobes being lined and blotched with purple. The undersides of the 
sepals are somewhat hirsute. Al. Bl. Cl. D2. El. (eb) F4Z. 
(Syn. D. Sarcostoma). 
Variety Dayanum—rather larger and more attractive than the type.
