CIRRHOPETALUM AMESIANUM ro Fe 
THE HON. F. L. AMES’ CIRRHOPETALUM. 
CIRRHOPETALUM. Sepalum posticum liberum, breve ; lateralia multo longiora, angusta v. acuminata, 
interdum longe caudata, basi parum dilatata, columnae pedi adnata, parallele patentia v. dependentia, interdum 
alte cohaerentia. Petala sepalis lateralibus multo breviora, saepius postico subsimilia, ovata v. lanceolata, integra 
v. eleganter ciliato-serrata. Labellum basi contractum, cum pede columnae articulatum v. mobile, in pedem incumbens, 
superne recurvum, integrum v. ad basin laminae utrinque auriculatum. Columna erecta, brevis, basi in pedem producta, 
superne bialata, alis utrinque in dentem v. brachium erectum productis; clinandrium postice-truncatum vy. in dentem 
brevem productum. Anthera terminalis, opercularis, incumbens, depresso-hemisphaerica, inappendiculata, decidua ; 
pollinia cerea, ad normam 4, per paria in loculos segregata, saepius tamen cujusve paria plus minus connata ita 
ut duo tantum in anthera appareant, inappendiculata. Capsula ovata v. oblonga, nunc fere fusiformis. 
Herbae caule seu rhizomate repente radicante, habitu Bulbophylli. Pseudobulbi ad axillas vaginaram scario- 
sarum apice unifoliata. Scapi floriferi ad latera pseudobulborum aphylli, multivaginati. Flores saepe speciosi, racemo in 
umbellam contracto, circa apicem scapi penduli, raris pedicellis abbreviatis subcapitati v. pedicellis dissitis laxius racemosi. 
Species ad 40, pro maxima parte Indiae Orientalis v. Archipelagi Malayani incolae, cum pauca Chinensi, 
uno Mascarensi et insularum maris Pacifici, altera parum anomala Australiana.

trinervium. Sepala lateralia connata, 1 1/4 poll. longa, 4 1/2 lin. lata, apice brevissime bidentata. Petala subulato- 
lanceolata, setifera, ciliata, 2 1/2 lin. longa, trinervia. Labellum carnosum, oblongum, acutum, recurvum, I 1/2 lin.

Cirrhopetalum Amesi ROLFE, supra. 
his is a very pretty Cirrhopetalum, native of Dutch India, introduced 
} by Messrs Linpen, L’Horticutrure INTERNATIONALE, Pare Leopold, 
# Brussels, with whom it has recently flowered. It produces slender umbels 
of porn about six to ten flowers. The united lateral sepals are light rosy-purple, 
passing into yellowish white on the margins and towards the apex. The rest of 
the flowers are yellow, except the lip and the ciliae on the dorsal sepal and 
petals, which are brownish red. It is dedicated to the Hon. F. L. Ames, of North 
Easton, Massachusetts, a liberal patron of horticulture, and the possessor of 
one of the finest Orchid collections in cultivation. 
It is not very easy to speak of the exact affinities of this plant, as the genus 
is in some deal of confusion at present. But it belongs to that section of the 
genus in which the dorsal sepal and petals are either ciliate or appendaged; and 
among these, it probably stands somewhere near C. Cumingii Linp., though 
that species possesses many important differences, and is easily distinguished 
by the different lateral sepals and petals. In looking through the different species 
of the group, I do not see any with which it can easily be confused.
