Hole : Ixora Butierwichii. 
3 
Stamens 4, inserted on the mouth of the corolla tube, alternating 
with the corolla-lobes, erect and exserted. Filaments 0-08 in. —0*1 in. 
long, glabrous, anthers linear, 0-22 in. —0*23 in. long, dorsifixed near the 
base, 2-celled and dehiscing longitudinally, more or less sagittate at base, 
the connective terminating above in a stout incurved point. 
Ovary inferior, 2-celled, one ovule in each cell, peltately attached to 
the septum, micropyle downwards. 
Style slender, glabrous, exserted, 0-12 in. —0-15 in. 
Stigmas 2, slender, 0-12 in. to 0-16 in. long. 
An epigynous disc covering the ovary from the insertion of the corolla 
to the base of the style. 
Fruit. Only immature fruit seen, subglobose, 0-23 in. in diameter, 
crowned obliquely by the persistent calyx lobes. Appears to be usually 
one-seeded. 
Distribution. 
This species is only known at present from Inbinyedwet in the Palwe 
Reserve of the Pyinmana Forest Division, in the Yamethin district of 
Burma. 
Herbarium specimens.

Notes. 
The determination of the affinities of this species and the selection of 
the diagnostic characters separating it from its nearest allies has been a 
matter of some difficulty. Many of the Indian species of Ixora are very 
variable and exhibit very remarkable differences ; for example, in the 
shape and size of the upper and lower leaves. In the absence of plentiful 
material, therefore, the range of variability of a species cannot be deter¬ 
mined with any accuracy, and such material is not yet available in the case 
of several species. The common forms of Ixora spectabilis, Wall, differ 
strongly from the present species in several characters, in addition to 
those which have been selected above as being of special, diagnostic 
value. In such forms, the leaves turn brown on drying and are hoary 
beneath, the pedicels are shorter and the calyx lobes are more hairy and 
more acute. At the same time somewhat doubtful specimens are found 
(e.g. Lace No. 167, Amherst, in herbarium Dehra Dun) which do not show 
these characters. Such forms require further study, but the writer is 
inclined to assign them provisionally to Ixora spectabilis , Wall. Kurz also 
notes that Ixora spectabilis, Wall, is a small tree and that its flowers are 
white. Additional characters separating Ixora pendula, Jack, from the
