50. DENDROBIUM discolor ; caulibus erectis fusiformibus, foliis oblongis 
obtusé emarginatis distichis, racemo terminali multifloro, sepalis peta- 
lisque lineari-oblongis patulis crispis, labelli crenulati lobis lateralibus 
acutis intermedio lanceolato acuto: lamellis 5 undulatis. 
_ Although obtained by Messrs. Loddiges from the Bota- 
nical Garden at Buitenzorg, I cannot recognize this species 
among those mentioned by Dr. Blume. It has a most sin- 
gular appearance, with stout erect stems four feet high, 
swollen in the middle, and terminal racemes of about 16 dingy 
yellowish brown flowers, as much curled and wavy as those 
of a Gloriosa. The lip has the same dull dirty colour, except 
along the middle, where it is decorated with five deep wavy 
plates of a bright violet. It is of the same section as the 
sweet-scented Dendrobium crumenatum, now so rare in our 
gardens, if it exist at all. 
51. LINARIA glandulifera ; annua, villoso-viscosa, pilis glanduliferis un- 
dique tecta, caulibus debilibus, foliis oppositis ovato-subrotundis, in- 
ferioribus petiolatis interdum vage dentatis obtusis, superioribus sessili- 
bus integerrimis, floribus axillaribus solitariis subsessilibus, calycinis seg- 
mentis ovatis; corollis exiguiis, labio superiore atropurpureo, inferiore 
palatoque flavo, calcare incurvo albo. Tenore Index Seminum, 1840. 
An annual with small purple flowers, sent from England 
to Professor Tenore by Mr. Fox Strangways. It is said to be 
allied to Linaria dealbata and lanigera ; but it differs from 
the first in its sepals being ovate and obtuse, not lanceolate 
and aeute, and also in its much smaller leaves and in the 
colour of the flowers. The sessile, not long-stalked, flowers 
divide it from L. lanigera. 
52. SEVERINIA buxifolia; arbuseula spinosa; foliis emarginatis perennan- 
tibus ovali-oblongis subsessilibus integerrimis parallele venosis obtusis ; 
floribus axillaribus fasciculatis vel solitariis Tenore Ind. Seminum, 1840. 
Under this name Professor Tenore distinguishes the 
Citrus buxifolia of the gardens, which he regards as a new 
genus, the character of which he states as follows : 
SEVERINIA. Calix quinquedentatus, corolla pentapetala, stamina decem 
pentadynamica, antheree semilunares biloculares, pistillum unicum 
stigma simplex. Acinus dispermus. 
53. DENDROBIUM elongatum. (Eudendrobium, foliis planis, floribus race- 
mosis, labello trilobo.) 4. Cunningh. in Bot. Reg. 1839. misc. 33.
