The plant should be kept in the greenhouse during summer, 
for if placed out of doors it is liable to suffer from excess of 
moisture. 
It is increased freely, as every leaf with a bad at, the base 
will soon form a good plant, if treated in the ordinary way. 
The following characters of some Orchidacee will serve 
to occupy an empty space in our pages. 
MICROSTYLIS caulescens; caule elongato folioso, foliis lanceolatis basi 
angustatis, racemo laxo multifloro cernuo, pedicellis filiformibus bracteis 
longioribus, labello acuminato intra basin biaurito.——The only caules- 
cent species yet described. The stem is about four inches long, and is 
covered with ten or twelve distichous leaves. The flowers are very small, 
green, in a thin raceme, about three inches long. ‘ound by the late 
Colonel Hall in Peru, in the valley of Lloa, at the elevation of 8000 
Jeet above the sea. (Herb. Hooker.) 
ISOCHILUS grandiflorum ; vaginis imbricatis, foliis distichis lineari-lanceolatis 
acutissimis, floribus solitariis axillaribus, bracteaé acuminata sepalorum 
dimidio zquali, sepalis acuminatissimis, petalis duplo brevioribus con- 
formibus, labello lineari-oblongo utrinque emarginato basi nudo, columna 
petalis parum breviore.———'This is very like I. graminifolium, but the 
flowers are four times as large, independently of the distinctions included 
in the foregoing character. Good specimens exist in the Royal Her- 
barium of Munich, collected in Peru by Henke ; but I find nothing like 
it in the Reliquiee Heenkeane. 
ISOCHILUS graminifolium (Humb. Bonpl. & Kunth, nov. g. et sp. pl. 1. 
340. t. 78.) ; vaginis imbricatis foliis distichis lineari-lanceolatis acutis- 
simis, floribus solitariis axillaribus, bracted acuminat& pedunculo bre- 
viore, sepalis aristatis, petalis conformibus dupld brevioribus, labello 
lineari-oblongo utrinque emarginato basi callo magno duro oblongo, co- 
lumna petalis dupld breviore. When not in flower this is undistinguish- 
able from I. grandiforum. Itis well figured in Humboldt and Bonpland’s 
work, excepting the analysis, in which the form of the labellum is inac- 
curate, and the presence of a hard oblong callus, called a purple stain 
in the description by M. Kunth, is overlooked. Peru, Mathews, 1064 ; 
Trunks of trees near Lloa, Jameson. (Herb. propr. & Hooker.) 
LALIA caulescens ; folio coriaceo lineari-oblongo caule tereti longiore, seapo 
elongato tereti e spatha membranaced cylindraced erumpente, racemo 
subdecemfloro, bracteis squamzeformibus erectis rigidis striatis, sepalis 
petalisque subsequalibus lineari-lanceolatis acutis, labelli postici nudi lobo 
intermedio obtuso crispo lateralibus parim longiore. A species very 
near L. cinnabarina. The flowers are apparently purple, and about the 
size of L. rubescens. The lip is perfectly destitute of all elevations or 
inequalities. In the herbarium of von Martius is a smaller plant from 
the same locality, with a three-flowered raceme, and much shorter Jeaves; 
apparently it is a mere variety. From the Serra de Piedade in the 
province of Minas Geraes in Brazil (herb. Martius).
