326 D. Prain— Some additional Papaveraceas. [No. 3, 
a welcome addition to western horticulture when its seeds are at length introduced 
to Europe. 
3. Cathcartia polygonoides Prain ; glabrescent, rootstock slender 
clothed with sheaths ; stems slender strigose; radical leaf solitary per¬ 
sisting long-petioled, canline leaves 2—3, lower long-petioled upper¬ 
most sessile clasping, ovate-oblong obtuse base cuneate, truncate or 
slightly cordate, margins entire or slightly incised crenate, sparingly 
hairy on both surfaces; flowers small blueish-white; style distinct, 
stigma small 2-3-lobed.

Stem 6-15 in. simple ; leaves 1^-2 in. by £—§ in.; radical petioles 3 in., lower 
cauline petioles 1-4 in. long. Flowers solitary 1 in. diam. nodding, pedicels long 
slender ; petals narrowly lanceolate apex acute margin entire ; stamens 16 in 2 rows 
of 8 each ; placentas 2-3. 
The flowers and unripe capsules of this plant are so remarkably like those of C. 
lyrata that there would seem no room for doubt as to its generic position. But it is 
at the same time remarkably like a small form of a plant from Yunnan described by 
M. Franchet as Meconopsis hetonicaefolia [ Plantae Delavayanae, 42, t. 12 (1889)] of 
which it has all the habit and, though on a smaller scale, exactly the foliage. A final 
judgment on both Cathcartia polygonoides and Meconopsis hetonicaefolia can therefore 
only be given when ripe fruit of both plants has been received. The specific differ¬ 
ences between the two plants are the fewer (16) stamens in the Chumbi plant than in 
the Yunnan one, which has 64 ; the narrower much smaller petals ; and the smaller 
ovary and stigma. As regards stigma Meconopsis hetonicaefolia more nearly approach¬ 
es Cathcartia villosa, but (like the two species now described) it has a long style ; it 
has also more stamens (64 in 2 rows of 32 each in place of 32 in 2 rows of 16 each as 
in C. villosa). The ovary and unripe capsules of Meconopsis hetonicaefolia, Cathcartia 
lyrata and C. polygonoides are remarkably similar ; knowing that one of them is a Cath¬ 
cartia the writer thinks it possible that the other two may eventually prove to be 
members of the same genus. 
7. (4.) CHELIDONIUM Tournef. 
Perennial glaucous herbs with yellow juice. Radical leaves 
petioled few erect or many rosulate, cauline few scattered, or 0, floral 0, 
or-2 terminal subopposed, or several near apex scattered. Flowers in 
fascicled or corymbose cymes. Sepals 2, petals 4, yellow or orange, 
convolute, stamens numerous, ovaries linear rarely ovate, 2-(rarely 3— 
4)-valved; style distinct stigma 2-lamellate lobes erect alternate with 
placentas, sinuses not projecting into arms. Capsule slender cylindric, 
rarely ovate, valves dehiscing throughout their length. Seeds shining 
smooth or opaque pitted, not scrobiculate, raphe crested. Species 9; 
7 Chinese, of which 1 (0. japonicum) extends to Japan, another ((?. 
majus) occurs also in Japan, Mongolia and Dahuria, extends westward 
to Britain and is naturalised in N. America; 1 North American; 
1 Himalayan.
