Bolbophyllum Thouars. 
9. B. tridentatum Krzl. n. sp. 
Rhizomate longe prorepente 2 mm. crasso, bulbis 5—8 cm. 
inter se distantibus obtuse tetragonis conicis 1,;—2 cm. altis basi 
fere 1,5 cm. crassis moncphyllis, foliis oblongis lanceolatisve ad 8 cm. 
longis 1—2 cm. latis acutis coriaceis apice vix v. non biapiculatis, 
scapis nutantibus quam folia bene brevioribus basi vaginatis ceterum 
nudis, racemis subcapitatis pauci-— plurifloris nutantibus, bracteis 
parvis oblongis acutis quam flores bene brevioribus 2—3 mm. longis. 
Sepalo dorsali oblongo obtuso concavo, sepalis lateralibus ovati- 
oblongis plus duplo longioribus basi connatis subobliquis acuminatis 
apice ipso obtusis, petalis minutis subquadratis v. brevissime ovatis 
supra triapiculatis v. tridentatis, apiculis brevibus subulatis, mediano 
vix longiore, labelli lobis lateralibus falcatis acutis pellucidis incurvis, 
labello ipso crasso carnoso ovato medio sulcato supra et infra dense 
papilloso ; gynostemii dentibus lateralibus latiusculis denticulo 1 late- 
rali instructis integrisve. — Flores rufinuli, sepala lateralia 6 mm. 
longa, dorsale 3 mm., labellum 1,5-—-2 mm. longum. 
The plant belongs to the group of mostly very indifferent looking 
species which are more or less similar to B. neilgherrense Wight and B. 
Careyanum Spreng. All have long creeping rhizomes, rather distant 
monophyllous bulbs, nodding more or less capitate spikes and most of them 
or all reddish flowers. The chief-character of this species consists in the 
three-pointed petals, a peculiarity not observed in any other species of the 
group. The lip in its shape does not differ very much from that of the 
allied species, but here the side-lobes are reduced to a thin transparent 
border whilst the middle-lobe consists of the strong fleshy body so common 
in Bolbophyllums.

Eria Lindl. 
10. E. semiconnata Kral. n. sp. 
Bulbis nummiformibus applanatis orbicularibus 8— 10 mm. diam. 
margine subrepandis supra retinerviis, foliis sub anthesi nullis, mihi 
non visis, floribus semper unicis brevi-pedicellatis, bractea ovata 
cucullata acuta quam ovarium longiore, flore nutante. Sepalo dor- 
sali obovato-oblongo brevi-acutato, sepalis lateralibus in unum basi 
gibbosum connatis apicem versus: liberis acutis cum dorsali conglu- 
tinatis non connatis, petalis obovatis obtusis, tota superficie minute 
crystallino-glandulosa, labello simplice ovato acuto basi plicato ibique 
umbonato; gynostemio perbrevi. — Flores extus et intus glabri, in- 
tense rubri, sepala 5—6 mm. longa, labellum 2 mm. longum. 
This curious little thing is the sixth species of the Porpax-group and 
is closely allied to E. ustulata Par. & Rehb. f. The differences are how- 
ever considerable enough to keep the plant distinct from EF. ustulata. The 
flowers of the latter are pubescent on the outside, those of our species 
are quite glabrous, the upper sepal is triangular and acuminate in E. ustu-
