This very delicate and beautiful species is very abundant on the Sisparah ghat (Nilgiris), 4-5000 feet elevation, on rocks 
and trunks of trees. I have never met with it elsewhere. Dr. Hooker considers it a variety of rivalis, but I do not think any one who saw 
the 2 plants growing would consider them varieties of the same species ; rivalis has very much larger flowers, and never has the long 
filiform appendage always present in this. Some botanists are inclined to unite rivalis with acaulis, but they could never be con¬ 
founded except in dried examples, acaulis has the lower lobe of the aloe entire, and in rivalis it is always deeply bifid. 
PLATE CLI. 
ImPATIENS ORCHIOIDES. (Bedd.) Scapigerous, leaves radical, orbicular to ovate with a deep cordate base, obtuse 
at the apex bristly crenate, furnished above with numerous weak hairs, below nearly glabrous, about 2 inches each way, petioles 3-5 
inches long, scapes about 6-7 inches long, racemosely 6-10 flowered towards the apex, flowers reddish-brown 10 lines long, pedicels 6-8 
lines long, bracteoles ovate, lateral sepals small ovate, vexilium ovate, aloe entire above, below produced into 2 long linear lobes, 
labellum ovate saccate without a spur, capsule glabrous, seeds numerous brown minutely scrobiculate. 
This very curious delicate species I have only observed on the Koondabs, growing on trunks of trees in sholas near the head 
of the Avalanche ghat (in flower in September) ; its flowers much resemble some species of Liparis. 
PLATE CLII. 
IMPATIENS GRANDIS. (Heyne.) Perennial, erect tall shrubby with thick fleshy branches perfectly glabrous, leaves 
glabrous oval to ovate acuminate, incurved-bristly-crenate, 5-6 inches long by 3 broad, petioles 2-5 inches long furnished with 2 
stipitate glands a little above the middle, peduncles axillary erect 4-6 inches long, flowers 2-6 umbellate on 1-2 inches long pedicels, 
flowers 2-3 inches long by 2 inches across white flaked with crimson, lateral sepals oval to lanceolate, vexilium broad ovate, aloe with 
the lower lobe twice as large as the upper one, labellum very variable sometimes produced into a long tapering straight or recurved 
spur sometimes only a deep oblong rounded bag. Heyne in Wall. Cat. 4759. Impatiens Hookeriana, Amt. 
This very fine species is very common in South Tinneve'lly, 1-4000 feet, and is also abundant in Ceylon ; it is easily propa¬ 
gated by cuttings. 
PLATE, CLIII. 
In a paper on this genus which I published in the Mad. Lit. Society’s Journal, I described 2 species under the names o£ 
I. crenata and 7. Alika ; they are both varieties of one species, but I have not specimens at hand to figure. It is a very pretty species 
of the Scapigeras group (and is perhaps not distinct from I. Stocksii, H. f. et T. from Canara, which I have not seen) ; it covers rocks on 
the Akka mountain and other localities on the Anamallays at 7000-8000 feet, but I have seen it nowhere else. 
The Scapigerae group is well marked, and to it belong I. modesta, Wight, (^-tenuis, Bedd. Mad. Journ.) ; I. scapiflora, 
Heyne; I-acaulis, Amt. ( = gracilis, Bedd. Mad. Journ.)-, I. rivalis, Wight (of which verrucosa, Bedd., is only a variety) quite 
distinct as a species from acaulis. I. Denisonii, Bedd., and I. orchioides, Bedd. The last two named I have only seen on the 
Koondahs (Nilgiris West,) but the others are pretty general throughout our western forests. 
The epiphytic group is also a well marked section : it contains Jerdonii, auriculata and viridiflora of Wight , and parasitica, 
Bedd • ; they are all epiphytic on the trunks and boughs of trees, and have short fleshy stems often 2 inches in diameter. Jerdonii, 
a most lovely species, is found on trees on the banks of the river just below the coffee estate on the Sisparah ghat, elevation 3-4000 
feet on the top of the Bramagherries, 5000, ana on the Palghat hills ; it is not found south of the Palghat gap ; auriculata and viridi¬ 
flora-are only found on the mountains in Tinnevelly and Travancore ; the former is very abundant on the Atti-aymallay and other 
localities, 5000 feet and upwards ; the latter I have only seen on the top of the Sevagherry ghat, 5000 feet; parasitica is restricted to 
the Anamallays, but is most abundant there all over the higher ranges and occasionally as low down as 4000 or 3500 feet. 
It is not easy to class the other species in well marked groups, as some species have both opposite and alternate leaves, and 
their flowers racemed or umbellate on the same plant. Some species are very local, and others widely dispersed. The following list 
may guide collectors of these interesting plants. 
* Leaves opposite, or verticelled peduncles 1 flowered, (in latifolia, Leschenaultia, and lucida, leaves often alternate.) 
I. Chinensis, L. (= I. fasciculata, Wa. ; I. heterophylla, Wall.)— Common, plains up to 8000 feet, very variable. 
I. oppositifolia, L. (= I. rosmarinifolia, Betz .)—Common 3-5000 feet, 
I. Gardneriana, W. —Sispara ghat, and Wynad, only 3-4000 feet. 
I. rufescens, Benih. —Common 4-7000 feet. 
I. tomentosa, Heyne (= ramosissma, Dalz.) —Common, 3-7000 feet. 
I. diversifolia, Wall .—Malabar (unknown to me), 
I. Lawii, H. f. et T .—Malabar, Canara, and Concan, 3-4000 feet. 
I. inconspicua, WA. (=1. filiformis, WA.) I. pusilla, Heyne). —Common, 3-8000 feet, very variable.
